M 08, Stn. 22, 618 m, ♂ 29.6 × 25.5 mm (IEO-CD-MZ 08 / 1777), 16 S (MZ 424903), COI (MZ 434752); M 08, Stn. 39, 631 m, ♂ 25 × 28.7 mm (IEO-CD-MZ 08 / 1908), 16 S (MZ 424904), COI (MZ 434753); M 08, Stn. 104, 692 m, ♀ 29.9 × 34.8 mm (IEO-CD-MZ 08 / 1801), 16 S (MZ 424905), COI (MZ 434754). Habitat and distribution. Currently there are only 6 species within the genus Homolodromia (Davie et al. 2015 a), being H. bouvieri the only one with representation in southern African waters (Kensley 1981; Martin 1992; Sasaki 2019), including Mozambique. General distribution of H. bouvieri: off Natal, 500 – 700 m (Kensley 1977, 1981), Kenia (863 m) and Mozambique (850 – 960 m) (Doflein 1904; Martin 1992). Nevertheless, the species was not reported in Mozambican waters in the checklist by Emmerson (2016 c). Results and remarks. Our specimens agree well with the descriptions given by Doflein (1904), the redescription of the species from specimens from Mozambique made by Martin (1992), and the comparison with the new species described recently from the northern Indian Ocean, H. rajeevani Padate, Cubelio & Jayachandran and previously confused with H. bouvieri (Padate et al. 2020). Three specimens were collected during the M 08, at depths between 618 – 692 m. These records extend the bathymetric range of this species in Mozambique waters, from 850 – 960 m to 618 – 960 m, and also its geographical distribution, being the specimens reported southernmost Mozambique. Colouration observed. The specimens had a homogeneous dark beige colour with a certain yellowish tone. DNA barcodes. 16 S and COI sequences were obtained for the three specimens. There are not sequences of these two genetic markers available for this genus on any public database. Therefore, these are the first 16 S and COI barcodes for this species and genus. In the case of 16 S each specimen showed a different haplotype differing in one mutation each, while only two haplotypes were observed for COI, differing from one another in one single mutation. Superfamily HOMOLOIDEA De Haan, 1839 [in De Haan, 1833 – 1850] Family HOMOLIDAE De Haan, 1839 [in De Haan, 1833 – 1850] The homolids are also known as “ carrier crabs ” or “ porter crabs ” due to their behaviour of carrying things on them, mainly helped by the P 5 that are modified for this (Miyake 1983; Guinot et al. 1995, 2013). The presence of fouling on their bodies is also quite common (Guinot & Wicksten 2015). According to Davie et al. (2015 a), Homolidae includes 14 genera and 70 species, while only six genera and seven species have been cited in Mozambican waters (Barnard 1950; Guinot 1967 a; Guinot & Richer de Forges 1995; Kensley 1981; Ng & Kumar 2015; Poupin 2018). Also, an Homologenus sp. was reported by Emmerson (2016 c) based on a personal communication by Chan from the MB-exp.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

M 07, Stn. 81, 548 m, ♂ 22.7 × 32.6 mm (IEO-CD-MZ 07 / 1900), 16 S (MZ 424906); M 08, Stn. 68, 244 m, ♂ 24.2 × 31.4 mm (IEO-CD-MZ 08 / 1821), COI (MZ 434755); M 09, Stn. 10, 305 m, ♂ 43.8 × 53.7 mm (IEO-CD-MZ 09 / 1806), 16 S (MZ 424907), COI (MZ 434756). Habitat and distribution. The geographic distribution of Homola orientalis is the IWP from the East African coast, Gulf of Aden to Australia, Hawaiian Islands, Polynesia, New Zealand (Kensley 1981) and Korea (Lee et al. 2013). It is the most common homolid species inhabiting the upper bathyal zone of the whole IWP. Its known depth distribution range is 38 – 650 m according to Guinot & Richer de Forges (1995) and 20 – 650 m according to Emmerson (2016 c). In Mozambican waters, it is reported at depths of 150 – 200 m (Emmerson 2016 c; Kensley 1981; Sasaki 2019). Results and remarks. Three males were collected during M 07, M 08 and M 09, from 244 to 548 m depth, thus extending its bathymetric distribution in Mozambique to deeper waters (from 200 up to 548 m). The specimens agree well with the description and figures in Guinot & Richer de Forges (1995). Some of them had epibionts, mostly barnacles. Colouration observed. The sepecimens were orange, with small bright orange spots, especially abundant along the legs, where they form not very well-defined transverse bands. The fingers were black, except in their proximal portion. DNA barcodes. The 16 S sequences of the males IEO-CD-MZ 09 / 1806 and IEO-CD-MZ 07 / 1900 are 100 % equals and fit 98.3 % with an incomplete sequence of 406 bp (hypervariable parts deleted) of H. orientalis from Taiwan (?) (MSLKHC-Hoori, Genbank code KJ 132562) included in the study by Tsang et al. (2014). The COI sequence of the specimens IEO-CD-MZ 09 / 1806 and IEO-CD-MZ 08 / 1821 (the same haplotype) differs 5.15 % from the sequence of H. orientalis from China (?), a sequence included in an unverified complete mitochondrial sequence (KT 182071) by Shi et al. (2016).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. The genus Homolochunia comprises four species which are found exclusively in the IWP, with H. valdiviae being the species with the widest distribution range. It is a benthic and tropical species (Palomares & Pauly 2020), inhabiting waters between 600 and 650 m depth according to Kensley (1981), and between 395 and 1000 m according to Poupin (2018). General distribution: IWP: Japan and Indonesia (Miyake 1983), India (Padate et al. 2020), Mozambique, Madagascar, New Caledonia, and Mayotte Island (Poupin 2010, 2018), off Natal (Kensley 1981) and Tanzania (Guinot 1967 a). Results and remarks. Our specimens agree well with the description and figures given by Guinot & Richer de Forges (1995). Ten specimens have been recorded, collected between March and April of M 07, M 08 and M 09, at depths between 530 and 620 m. These specimens did not carry anything in the P 5, but they do have the entire carapace covered by soft fouling. In addition, some specimens had small sponges on the dorsal side of the P 2 - P 4 merus. Colouration observed. Variable. The specimens from 2007 were pinkish, not very striking, with the cephalothorax darker, possibly as a consequence of the fouling attached to their dense tomentum, while specimens from 2009 were of a quite homogeneous bright orange colour. The pseudorostral spines and the P 1 and P 5 legs ended in a whitish colour. DNA barcodes. Sequences of 16 S (the same haplotype) were obtained for five specimens (IEO-CD-MZ 08 / 1796, 1804 (2) and 1805 (2 )), being the firsts made available for this species. Five sequences of COI (628 to 636 bp) were obtained for the same five specimens and represent five haplotypes differentiated in one to three positions. The sequence of the male IEO-CD-MZ 08 / 1796 fit 100 % with a COI sequence of H. valdiviae (Bold MDECA 043 - 10) collected in the MB-exp and deposited at the MNHN (MNHN _ IU 200810122).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Seven species of Moloha are known in the IWP (Ng & Kumar 2015), of which only three are recorded in the WIO. Moloha alcocki inhabits the continental shelf off southern African waters from Namibia to Mozambique (Kensley 1980 a, 1981) and Maldives (Gordon 1950). It has a wide depth range, between 80 and 800 m, being reported at 312 m in Mozambican waters (Kensley 1980 a, 1981). Results and remarks. The two female specimens agree well with the description and figures of Guinot & Richer de Forges (1995) and clearly differ from the close species Moloha major (Kubo), in the following features: non-cylindrical P 2 - P 4, armed on the upper edge of 4 - 5 large inclined spines, and another strong distal one, and in the branchial areas of the carapace, near of the union with the cardiac areas, bearing numerous small spines. The two specimens were collected in the same station, at 254 m, in 2009. They were large and had barnacle epibionts on their carapace and legs. These specimens are the second record of the species in Mozambique and extend its minimum depth from 312 to 254 m in Mozambican waters. The variation of names (changes and synonyms) has made that even today there is a great confusion on the species nomenclature, being reported differently in some publications and online resources: as Homola (Paromola) alcocki (Stebbing, 1920), Homola alcocki (Stebbing 1920), Latreillopsis alcocki Stebbing, 1920, Paromola alcocki (Stebbing, 1920), Thelxiope alcocki (Stebbing, 1922) (WORMS 2021). Also, it appears indistinctly as M. alcocki and Paromola alcocki in GBIF. org (2021, unpublished record), or as Maloha alcocki in Emmerson (2016 b). Colouration observed. The specimens were bright orange, not uniform, but marble-like in appearance, with small lighter and darker orange patches, even red, both on the cephalothorax and on the ambulatory legs. The dactyls from P 2 to P 4 are darker, turning to reddish brown, without spots. The chelipeds’ fingers were black. After preservation in ethanol, the specimenscarapaces turned to beige colour, the legs and chelipeds to very light brown and only the finger tips remain with their black original colour. DNA barcodes. Only a 16 S sequence (526 bp) was obtained from one of the ovigerous females. This sequence fits 99.43 % (3 mutations) with the sequence of Moloha major (Kubo) (as Moloha majora) (KT 182069), a complete mitochondrial genome by Shi et al. (2016).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Paromolopsis boasi was the only species of the genus worldwide, until Paromolopsis piersoni (Schweitzer et al. 2004) was described from fossil records in Oregon (Pacific Northwest of North America). This species presents an IP distribution: Madagascar, Channel of Mozambique, Mayotte Island, La Reunion, Sri Lanka, Andaman Island, Laquedives Island, Indo-Malaysian Archipelago, New Caledonia, Queensland and Japan. It inhabits mud bottoms, from 284 to 1124 m (most common between 400 and 700 m) (Guinot & Richer de Forges 1995; Poupin 2010, 2018). Results and remarks. This work provides the first record of P. boasi from Mozambique waters. Only two specimens of P. boasi were collected in M 08 and M 09, between 578 – 631 m depth. Our specimens were identified using the descriptions given by Guinot & Richer de Forges (1995) and Schweitzer et al. (2004). Guinot and Richer de Forges (1995) had already doubted about the validity of a single species from all the known localities of P. boasi, pointing out differences in the dorsal carapace ornamentation, variation in body tomentum and carapace proportions and different sizes of frontal spines. This fact was also raised by Padate et al. (2020), who found differences between Indian and Pacific specimens. Guinot and Richer de Forges (1995) already suggested the potential separation of P. boasi into at least two species. A review of this genus, including genetic analysis of P. boasi specimens from different areas is recommended to clarify this issue. The most remarkable characteristics of these two specimens (see Figure 3) are: anterolateral spines acute but not sharpening towards the end; dorsal face of the carapace quite rough and grainy; merus length of P 5 does not exceed the anterolateral spine; long setae on the edges of the carapace, as well as on the edges of the ambulatory legs; the top edge of P 2 - P 4 merus armed with separated spines of different size, not uniform in number neither between different pereiopods nor between specimens. The biggest specimen (IEO-CD-MZ 08 / 1827) is an ovigerous female that responds to the next pattern from the outside inward (see Figure 3 B): right side, P 2, two sharp, curved and well separated medium-size spines + two small blunt and less separated spines or tubercles, not clearly visible; P 3, four well visible spines on merus, that decrease dorsally in size and space between them; P 4, three well visible, pointed and curved spines, diminishing in size dorsally; left side, P 2, small tubercles in the most proximal area; P 3, three well visible and curved spines (two last broken); P 4, two well visible and curved size-decreasing spines. The male (IEO-CD-MZ 09 / 1762), responds to (see Figure 3 C): right side, P 2, two big, pointed and curved spines + four smaller spines, neither pointed nor curved, which decrease in size dorsally until being almost inconspicuous and adjacent; P 3, four pointed and curved and dorsally size-diminishing; P 4, four pointed and curved spines becoming much smaller towards the dorsal zone; left side, P 2, three big, pointed and curved spines, being the two first specially big + two neither pointed nor curved small spines, almost inconspicuous; P 3, five spines that decrease in size and space between them, the last neither pointed nor curved, P 4, four pointed and curved spines, with dorsally diminishing size. All these characters are in line with the characteristics of the specimens cited in waters of the Indian Ocean (Guinto & Richer de Forges, 1995). Colouration observed. Carapace was bright orange, with the most depressed areas of the gastric zones white. Meri of the ambulatory legs were also orange, slightly pinker in their proximal area; carpi are orange-pink; propodi are whitish with pink tones and the dactyli almost white. DNA barcodes. 16 S and COI sequences obtained for the two specimens are equal in 500 and 639 bp, respectively. The 16 S sequence fits 100 % with an incomplete sequence of P. boasi of 406 bp (hypervariable parts deleted) from Taiwan (?) (NTOU B 00091, Genbank code KJ 132606) included in the study by Tsang et al. (2014). The COI sequence is the first one available for this species. Family LATREILLIIDAE Stimpson, 1858 According to Davie et al. (2015 a), Latreillidae includes two genera, Latreillia P. Roux and Eplumula Williams, and seven species, three of them cited in Mozambican waters (Latreillia metanesa Williams, Latreillia pennifera Alcock and Latreillia valida De Haan) (Kensley 1981; Poupin 2010, 2018, Emmerson 2016 b, c). Free living and mostly deep water species, individuals typically carry seaweeds, hydroids, gorgonians and / or corals on them (Davie et al. 2015 b).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

IWP, from East Africa (Somalia, Kenya, Mozambique, Madagascar) to French Polynesia and the Hawaiian Islands at depths between 22 and 806 m (Castro et al. 2003), with records in South China Sea, Taiwan, Philippines, Indonesia, Vanuatu, New Caledonia, and Japan (Sasaki 2019). In Mozambican waters, the species is recorded between 112 and 403 m (Castro 2013). It inhabits bottoms of sand, foraminifera, coral and rock (Williams 1982). Results and remarks. Only one specimen was studied, being an ovigerous female, collected in March 2009 (M 09) at 374 m depth. This specimen agrees well with the descriptions and figures in Castro et al. (2003). The specimen was collected badly damage. Colouration observed. The carapace was crossed longitudinally by orange and beige lines, which curve at the posterior edge of the carapace. The ambulatory legs, as well as the chelipeds, bear orange and beige transverse lines. DNA barcodes. There are not sequences available for this species on any public database. Thus, the 16 S sequence is the first one for this species and is close (98.49 %), at intrageneric distance, to one sequence of Latreillia valida (MK 204361).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. WIO, from South Africa and Madagascar, to Western Australia and Western Pacific Ocean, from Japan to as far east as Tonga. The depth range recorded for the species is 30 – 898 m (Castro 2013), while in Mozambican waters is 112 – 898 m according to Castro (2013) and 30 – 731 m according to Emmerson (2016 b, c). Results and remarks. Two specimens, one male and one ovigerous female, were collected at the same station in March 2009 (M 09), at 212 m depth. These individuals were damaged, with some broken legs. Our specimens agree well with the descriptions and figures in Castro et al. (2003). Colouration observed. The carapace was almost transparent, with certain orange tone, covered with longitudinal red lines and another wider and complete red line, which borders all its posterior edge. Transverse red bands were along the ambulatory legs, being not uniform and little marked. DNA barcodes. 16 S and COI sequences of both specimens are equal in 412 and 636 bp, respectively. 16 S and COI sequences fit 99.28 % (only differ in one mutation) and 99.69 % (differing in two mutations), respectively, with the sequences of L. valida (MK 204361), a mitochondrial complete genome obtained by Bao et al. (2019). Superfamily RANINOIDEA De Haan, 1839 [in De Haan, 1833 – 1850] There is some confusion regarding the taxonomic status of Superfamily Raninoidea. Some authors and web platforms consider it to comprise two families, Raninidae De Haan, and Lyreididae Guinot (Davie et al. 2015 a), while others consider the Lyreididae as a subfamily, Lyreidinae, within the Raninidae as Ribes (1989), Emmerson (2016 b, c), and WORMS (2021). In this work we have followed the more recent classification by Davie et al. (2015 a), considering Raninidae and Lyreididae as two independent families. Family LYREIDIDAE Guinot, 1993 According to Davie et al. (2015 a), this family includes two genera (Lyreidus De Haan and Lysirude Goeke) and six species. These species, known as “ frog crabs ”, are mainly distributed in warm and tropical waters of the Atlantic and IWP (Poor 2004). Only Lyreidus brevifrons Sakai has been cited in Mozambique waters (Emmerson 2016 b, c). A Lyreidus sp. was also reported for Mozambique by Emmerson in his checklist.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Species distributed throughout Japan, the South China Sea, west of the Philippines and Dar-es-Salaam, Tanzania (Sakai 1976), Madagascar, Reunion Island (Poupin 2010; Ribes 1989) and New Caledonia (Poupin 2010). Results and remarks. Our specimens agree well with the descriptions and figures in Goeke (1985). Eight specimens were collected during March and April of M 07, M 08 and M 09, at depths between 190 and 530 m. These records confirm the presence of L. brevifrons in Mozambican waters, and extend its depth range to deeper waters up to 530 m. Colouration observed. Orange-brown, with the gastric and intestinal areas a little clearer, almost orange. Ambulatory legs were dorsally orange coloured, not homogeneous, with some clearest and pale patches, almost white. The ventral side of the specimens, legs and chelae were very pale, between rose and pale orange. Antennules and ocular peduncles were orange dark. A wide white line separates the gastric and branchial areas, and a big clear spot in both sides of the branchial area was observed in some individuals. DNA barcodes. For 16 S three equal sequences of 424, 500 and 507 bp were obtained, that fit 100 % with a sequence of L. brevifrons from Taiwan (KM 983394), a complete mitochondrial genome obtained by Shi et al. (2015). The three COI sequences represent two haplotypes, differing in two mutations, and fit 98.58 and 98.91 % (nine and seven mutations), respectively with the COI sequence of the same specimen of L. brevifrons from Taiwan (KM 983394). Family RANINIDAE De Haan, 1839 [in De Haan, 1833 – 1850] According to Davie et al. (2015 a), this family includes ten genera and 40 species. Only the genera Cosmonotus (White), Notopus (De Haan), Ranina (Lamarck) and Raninoides (H. Milne Edwards) have been cited off Mozambique (Emmerson, 2016 b, c).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

The known distribution of Raninoides crosnieri is the type locality, Madagascar, at depths between 160 and 210 m (Ribes 1989). Results and remarks. Only one specimen was recorded at 190 m depth in M 07. It is a male mostly agreeing with the description of R. crosnieri given by Ribes (1989), although not completely. There are characteristics that clearly distinguish it from Raninoides personatus Henderson, the other similar species of the Indian Ocean, and agree with the R. crosnieri description, such as: a sub-distal spine in the carpus of the chelipeds (although it is accompanied by a distal one) and the edge of the carpus rough; the upper edge of P 4 somewhat concave; on the upper edge of P 5 which there are indications that there was a spine in each, which are broken. However, the rostrum of this specimen (see Figure 5 A) differs with that described by Ribes (1989) for R. crosnieri (see Figure 5 B), and rather fits the description of the rostrum of R. personatus “ rounded at its end ” (see Figure 5 C). Ribes (1989) considered the rostrum shape as one of the main differences separating R. crosnieri from R. personatus, and therefore this new evidence put under question the taxonomic validity of this feature. This is the first record of R. crosnieri in Mozambique waters, and the second one of this species worldwide. Colouration observed. The cephalothorax and pleon were orange-brown, with marble-like spots. The legs and chelipeds were light beige, with some not very well-defined faint brown-orange spots. DNA barcodes. There are not sequences available for this species on any public database. The 526 bp sequence of 16 S obtained for the specimen IEO-CD-MZ 07 / 1910 is the first genetic marker for this species.

(2015 a), this family includes nine genera and 89 species. Only two of these genera have been recorded in Mozambican waters, Calappa Weber and Mursia Desmarest (Emmerson 2016 b, c; Lai & Ng 2006; Spiridonov & Apel 2007). Calappidae crabs are known as box-crabs and inhabit from shallow to deep waters, usually burying (Davie et al. 2015 a).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

M 07, Stn. 37, 243 m, ♂ 88.8 × 65.1 mm (IEO-CD-MZ 07 / 1923); M 08, Stn. 15, 283 m, ♀ 88.8 × 64.4 mm (IEO-CD-MZ 08 / 1815), 16 S (MZ 424923), COI (MZ 434769); M 09, Stn. 4, 258 m, ♀ 121.1 × 82.6 mm (IEO-CD-MZ 09 / 1791), 16 S (MZ 424924), COI (MZ 434770). Habitat and distribution. This species was confused for many years with Calappa japonica Ortmann, 1892, until it was described by Lai & Ng (2006) as a new species. Since then, C. japonica has been confined to the Pacific and Calappa africana to the Southeast African coast, South Africa, and Mozambique (58 m) (Barnard 1950, 1955; Kensley 1981), Kenia and Somalia (type locality, 70 – 80 m) (Lai & Ng 2006). Results and remarks. To identify our specimens, we use the original description (Lai & Ng 2006) and a posterior revision of C. africana together with C. japonica and C. exanthematosa Alcock & Anderson made by Ng et al. (2011). The three studied individuals were collected in the three surveys (M 07, M 08 and M 09) at depths of 243, 283 and 258 m, respectively. These specimens were initially identified as C. africana as they had many diagnosis characters similar to those of the original descriptions by Lay & Ng (2006), although other characters did not totally agree with them. It is the case for the second male pleopods (G 2) (see Figures 6 A, B) which are more curved, distally crook-like, as described for C. japonica by Galil (1993) (see Figure 6 D) than “ G 2 subequal in length to G 1, slender, curved, distal tip rounded ” as described by for C. africana Lay & Ng (2006) (see Figure 6 C). Our records extend the depth range in Mozambican waters from 58 up to 283 m. Colouration observed. Lai & Ng (2006) described the colour of the freshly preserved paratipe of C. africana as follow: “ … the dorsal surface of the carapace is beige to light brown in colour, speckled with salmon pink to light red mottles ”. Barnard (1950) also described the colours of preserved specimens of C. japonica, which today must be referred to C. africana: “ As preserved, pale with salmon pink mottling around the pustules and on hinder half of the carapace ”. The colour of our preserved specimens agrees well with those descriptions. Photographs taken from two fresh specimens show the following live coloration pattern: the dorsal carapace surface, as well as the outer part of the chelae varies from brown-red to yellow. The female captured in M 08 (IEO-CD-MZ 08 / 1815) was more yellowish, while the male from M 07 (IEO-CD-MZ 07 / 1923) was more reddish (see Figures 4 C, D). In addition, the carapace has a dorsal pattern of large yellow spots surrounded by red, but without any reticulate pattern, which is typical of C. japonica (Ng et al. 2011). The spots on the upper half of the carapace were marked, even with volume (as tubercles), while the ones in the lower half were much less pronounced and fading. DNA barcodes. 16 S and COI were obtained for two specimens, IEO-CD-MZ 08 / 1815 and IEO-CD-MZ 09 / 1791. The 16 S sequences had no differences between them, and for COI two haplotypes differing only in one position were obtained. There are not sequences available for C. africana on any public database. However, the 16 S sequences fit 99.44 % (only differ in three positions) with an unpublished sequence of C. japonica (MG 029426) obtained by Deepak et al. probably from an Indian specimen and fit 99.56 % (only differ in two positions) with a shorter sequence (450 bp) of C. japonica from Japan obtained by Ewers-Saucedo et al. (2016). Respect to COI the two haplotypes differ in one or two mutations of another unpublished COI sequence (KT 003706) of Calappa sp. (voucher CSP 2) also obtained by Deepak et al. and probably also belonging to an Indian specimen. According to these data, probably the Calappa sp. is an individual of C. africana, a closer species to C. japonica as indicated by the low divergence in the 16 S gene, and both species could be sympatric in Indian waters.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. This is one of the three species of Mursia recorded in Southeast African waters (Emmerson 2016 b, c; Spiridonov & Apel 2007). Its geographical distribution ranges from Kenya to Mozambique, at depths between 177 – 290 m (Spiridonov & Apel 2007) and Thailand (Sasaki 2019). This distribution could be extended to Somalia if we consider a specimen deposited in the Collection Crustacea SMF (Senckenberg Institute, Germany), record published by GBIF. org (2021, unpublished record). Results and remarks. These two specimens collected in M 07 and M 08, agree well with the description by Galil (1993). The specimens were caught at depths between 211 and 366 m, this extending the depth range in Mozambique and worldwide, up to 366 m. Colouration observed. The carapace and chelae were orange brown with small red tubercles and to a lesser extent, with white tubercles, these mainly through the intestinal region. Bigger tubercles and the anterolateral edge of the carapace were red with white tips. Pereiopods were cream coloured ventrally, and light orange dorsally. After preservation, both in alcohol and formaldehyde, specimens keep the dorsum of carapace light brown, with the deeper areas between tubercles reddish and ambulatory legs in beige. DNA barcodes. There are not available sequences for this species on any public database. The 16 S sequences are equal for both specimens and there are two haplotypes for COI (differing in three mutations), and in both cases differ markedly from the other 16 S and COI sequences of Mursia spp. in Genbank and BOLD.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Mursia flamma is distributed in the southwest of the WIO, between Kwazulu-Natal in South Africa, Mozambique and Madagascar (Emmerson 2016 b, c; Galil 1993; Spiridonov & Apel 2007), between 210 and 520 m depth (Emmerson 2016 b, c). Results and remarks. One single male specimen was collected at 382 m depth. For identification, the keys provided by Galil (2003) and Spiridonov & Apel (2007) were used. This specimen does not completely conform to the original description of M. flamma. In addition, there are certain characters that do not match the posterior redescription made by Galil (2003). The median tooth of the rostrum of our specimen is not triangular, as described by Galil (2003), but rounded, as described in the review of M. flamma made by Spiridonov & Apel (2007). Galil (2003) reported three spines on the merus of the chelipeds, but our specimen has four, one of them being minute. While Spiridonov & Apel (2007) described three spines, a minute fourth spine can be appreciated in the merus of the cheliped in some pictures of M. flamma of the MHNH, this suggesting that the number of spines on the merus of the cheliped could be three or four, the fourth being a tiny one (see Figure 7). Thus, the number of spines of the cheliped might not be a distinctive character for M. flamma. Colouration observed. Our specimen was quite strong reddish-brown, with slightly lighter tubercles, the larger ones with whitish tips, as well as the spines on the posterior margin of the carapace. Chelipeds have the same colour as the carapace, and pereiopods were lighter reddish tone with the proximal part of the merus and the dactyli whitish. DNA barcodes. The specimen was preserved in formalin and therefore, it was not possible to get DNA sequences.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Known only from Reunion Island and Madagascar in the southwestern Indian Ocean. The reported bathymetric range is 350 - 720 m (Davie 1991). Results and remarks. The keys from Crosnier (1976), Davie (1991) and Davie & Ng (2012) were used to identify the seven specimens collected at depths between 511 – 643 m in the three surveys. In all specimens, a combination of the features described by Crosnier (1976) for P. guezei and by Davie & Ng (2012) for P. seani were observed. Davie & Ng (2012) differentiated both species based in several characters like: setal coverage from dorsal carapace, carpus and chela; definition of carapace regions; spines of the carapace margins; number of horizontal rows of spines in claws; spines on the carpus of the claw or shape of the male telson. However, none of the seven specimens clearly matches with the complete description of any of both species, and finally we have opted for P. guezei considering that P. seani was described on the basis of one single individual, therefore not covering all the expected variability of the species as well as the features of the male. Colouration observed. Specimens were covered by a dense brownish tomentum overall and have pink pereiopods with white dactyls and their tips black. The fingers of the chelae were black. DNA barcodes. Since there are not sequences available for this genus on any public database, the two equal 16 S sequences of the specimens from MZ 08 and MZ 09 as well as the three COI sequences (three haplotypes), are the first DNA markers for this species as well as for the genus. Superfamily ERIPHIOIDEA MacLeay, 1838 Family DAIROIDIDAE Števčić, 2005 This family was described in 2005 by Števčić only for the genus Dairoides Stebbing. Previously, these species were considered xanthid crabs (Barnard 1950; Kensley 1981), later parthenopids (Sakai, 1976), rather than Eriphiidae. In accordance with Davie et al. (2015 a), this family includes only one genus and three species, Dairoides kusei (Sakai), Dairoides margaritatus Stebbing and Dairoides seafdeci Takeda & Ananpongsuk.

03D487F82131FFF7FF71D837BE7FFCB4.taxon	discussion	Results and remarks. The keys from Crosnier (1976), Davie (1991) and Davie & Ng (2012) were used to identify the seven specimens collected at depths between 511 – 643 m in the three surveys. In all specimens, a combination of the features described by Crosnier (1976) for P. guezei and by Davie & Ng (2012) for P. seani were observed. Davie & Ng (2012) differentiated both species based in several characters like: setal coverage from dorsal carapace, carpus and chela; definition of carapace regions; spines of the carapace margins; number of horizontal rows of spines in claws; spines on the carpus of the claw or shape of the male telson. However, none of the seven specimens clearly matches with the complete description of any of both species, and finally we have opted for P. guezei considering that P. seani was described on the basis of one single individual, therefore not covering all the expected variability of the species as well as the features of the male.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

It could be an endemism of southern Africa, distributed from KwaZulu-Natal to Mozambique (Stebbing 1920; Barnard 1950; Guinot 1967 a, b; Kensley 1981; Emmerson 2016 b, c) at depths between 20 to 180 m (Kensley 1981). Results and remarks. One female specimen of Dairoides margaritatus was collected in M 07 at 129 m. The keys by Guinot (1967 b) were used for identification. Colouration observed. Pictures of the fresh specimen are not available. DNA barcodes. There are not 16 S and COI sequences of this species on any public database, and therefore, these are the first ones. In Genbank there are only one 16 S (HM 637979) and one COI (HM 638030) sequences available for Dairoides kusei based in one specimen (ULLZ 9183) from Hawaii obtained by Lai et al. (2014). The 16 S sequence differs in three mutations (in 533 bp, 99.43 % similarity) that could be in the intrageneric range, as well as in the case of the COI sequence varying in 58 positions (in 588 bp). The results (especially for COI sequence) of the BLAST and BOLD searches also suggest the affinity of Dairoides with Parthenopidae, as already pointed out by Lai et al. (2014).

Habitat and distribution. IWP, from South Africa (Barnard 1950) to the southwestern Pacific Ocean (Guinot & Richer de Forges 1980) at depths of 464 – 800 m, being one of the few Carcinoplax species mainly distributed on the slope and not on the continental shelf (Castro 2007). The morphology of C. ischurodous differs considerably from the rest of its congeneric species, this suggesting the possibility of belonging to a different genus (Guinot 1989; Manning & Holthuis 1988). Results and remarks. The three specimens, each one collected in one of the three surveys at depths between 608 and 631 m, perfectly fit the descriptions and figures of Castro (2007). The species was reported in the latest checklist for the area (Emmerson 2016 c), but only from records off South Africa. Thus, this is the first record of C. ischurodous in Mozambican waters. Anyway, we are aware from GBIF. org (2021, unpublished record) of the existence of conserved specimens of C. ischurodous housed on the MNHN from the MB-exp (2009) (unpublished). Colouration observed. Fresh specimens looked polished, with the carapace orange-brown with some white small spots, and the posterolateral margin lighter; the chelipeds were bright orange with some deep-orange patches on the merus; the fingers and the knob at the beginning of the fingers were bright white. The pereiopods were pale orange with unarmed and pinkish dactyls. DNA barcodes. There are not sequences of this species on any public database. The two equal 16 S sequences and the two COI sequences (two haplotypes) are the first ones for this species. The BLAST search results for 16 S show a 94.01 % similarity with Goneplax rhomboides (JN 591655) (27 mutations, including two gaps), and 93.79 % with Carcinoplax surungensis (FJ 943433) (36 mutations, including five gaps), and a longer distance respect to Carcinoplax longimanus (this study), 45 mutations, including four gaps. All these evidences support the possibility that C. ischurodous could belong to a different genus closer to Goneplax than to Carcinoplax.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Wide distribution from South and East Africa to the western Pacific Ocean (Korea and Japan to Indonesia) from 6 to 377 m depth (Castro 2013). In waters of Mozambique, it was cited between 66 – 377 m (Emmerson 2016 c) and between 80 and 120 m (Sasaki 2019). It is a very abundant species in a wide depth range and quite common in the bycatch of shrimper trawl fisheries (Oh et al. 2009; Sobrino et al. pers. comm.). They are benthic crabs, which inhabits mud or sand bottoms where they build burrows (Castro 2007; Hsueh & Hung 2009; Kensley 1981; Ng 1998). Results and remarks. Our specimens agree well with the descriptions and figures by Castro (2007). We checked 19 specimens of C. longimanus collected in M 07, M 08 and M 09 surveys, at depths between 244 and 336 m. There is great size-related morphometric variability in this species. The antero-lateral teeth are polished over time and become smaller in relation to the specimen size with growing, in a way that the carapace edge seems to be unarmed in the biggest individuals. Moreover, there is also a certain sexual dimorphism, as the females and juvenile males have short chelipeds, while the chelipeds are exceptionally long in adult males (see Figure 8 D), the merus and propodus being almost three times longer than in juveniles and females while the carpus remains practically the same length (see Figure 8 E). These features were also illustrated by Yamashita (1965), Guinot (1989) and Ikeda (1998). Colouration observed. Specimens looked polished, the carapace being orange-brown, the chelipeds bright orange with the fingers, the spines and the knobs at the beginning of the propodus, bright white. The pereiopods were orange with the junction between merus-carpus and carpus-propodus white. Dactyli were brown, partly due to their dense tomentum. After preservation in ethanol or formalin, females and juveniles acquire a uniform bone colour, while the carapace of big males turns to brown. DNA barcode. The two 16 S sequences obtained for specimens from M 08 and M 09 fit 100 % with an incomplete sequence of C. longimanus of 406 bp (hypervariable parts deleted) from Taiwan (?) (NTOU B 00091, Genbank code KJ 132525) included in the study by Tsang et al. (2014). Respect to COI sequences, each specimen presents a different haplotype (differing in just one mutation). These sequences show a similarity between 98.89 and 99.21 % with three unpublished (private) sequences of specimens of Carcinoplax longimanus (as C. longimana) from South Korea deposited in BOLD. However, they present a similarity of 84.4 % with C. ischurodous (99 mutations) that underline the above-mentioned differences of this species with congeneric ones, supporting the possibility of a different genus for C. ischurodous. Superfamily LEUCOSIOIDEA Samouelle, 1819 Family LEUCOSIIDAE Samouelle, 1819 Leucosiidae is one of the most extensive family of crabs. It comprises three subfamilies, Cryptocneminae Stimpson, Ebaliinae Stimpson, and Leucosiinae Samouelle, with a total of 71 genera and 488 species (Davie et al, 2015 a). They have similar shapes, usually small with rounded carapace, hence they are known as nut or pebble crabs (Poore 2004; Ward & Rainer 1988). According to Emmerson (2016 b, c), ten species of Leucosiidae belonging to the three subfamilies have been cited in Mozambique waters, most of them in intertidal or shallow waters. This group has been intensively studied in recent years, with the description of new genera and species, and replacement of several species (Galil 2003 a, b, c, 2005, b, 2006 a, b, 2009; Galil & Ng 2010).

Moreover, there is also a certain sexual dimorphism, as the females and juvenile males have short chelipeds, while the chelipeds are exceptionally long in adult males (see Figure 8 D), the merus and propodus being almost three times longer than in juveniles and females while the carpus remains practically the same length (see Figure 8 E). These features were also illustrated by Yamashita (1965), Guinot (1989) and Ikeda (1998). Colouration observed. Specimens looked polished, the carapace being orange-brown, the chelipeds bright orange with the fingers, the spines and the knobs at the beginning of the propodus, bright white. The pereiopods were orange with the junction between merus-carpus and carpus-propodus white. Dactyli were brown, partly due to their dense tomentum. After preservation in ethanol or formalin, females and juveniles acquire a uniform bone colour, while the carapace of big males turns to brown.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

The two 16 S sequences obtained for specimens from M 08 and M 09 fit 100 % with an incomplete sequence of C. longimanus of 406 bp (hypervariable parts deleted) from Taiwan (?) (NTOU B 00091, Genbank code KJ 132525) included in the study by Tsang et al. (2014). Respect to COI sequences, each specimen presents a different haplotype (differing in just one mutation). These sequences show a similarity between 98.89 and 99.21 % with three unpublished (private) sequences of specimens of Carcinoplax longimanus (as C. longimana) from South Korea deposited in BOLD. However, they present a similarity of 84.4 % with C. ischurodous (99 mutations) that underline the above-mentioned differences of this species with congeneric ones, supporting the possibility of a different genus for C. ischurodous.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

03D487F8213CFFF8FF71D96FBF35FBDC.taxon	discussion	Leucosiidae is one of the most extensive family of crabs. It comprises three subfamilies, Cryptocneminae Stimpson, Ebaliinae Stimpson, and Leucosiinae Samouelle, with a total of 71 genera and 488 species (Davie et al, 2015 a). They have similar shapes, usually small with rounded carapace, hence they are known as nut or pebble crabs (Poore 2004; Ward & Rainer 1988). According to Emmerson (2016 b, c), ten species of Leucosiidae belonging to the three subfamilies have been cited in Mozambique waters, most of them in intertidal or shallow waters. This group has been intensively studied in recent years, with the description of new genera and species, and replacement of several species (Galil 2003 a, b, c, 2005, b, 2006 a, b, 2009; Galil & Ng 2010).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Tanaoa pustulosus is distributed along the IP (Fiji, New Caledonia, New Zealand, Japan, Taiwan, Indonesia, Philippines, Andaman Sea, Seychelles, Comoro Islands, Madagascar, Reunion, Mozambique Channel and East Africa), at 85 – 977 m depth (Galil 2003 c). Results and remarks. Our specimens agree well with the descriptions and illustrations included in the work of Galil (2003 c), in which the genus Randallia Stimpson was redefined, and the new genus Tanaoa erected. Thirteen specimens of T. pustulosus, collected in the three surveys (M 07, M 08 and M 09), at depths between 190 and 658 m, were examined. These specimens are the first records of T. pustulosus in Mozambican waters. After our surveys, some specimens were collected in the MB-exp in 2009 (Chan & Ng, pers. comm. to Emmerson, 2016 c). Colouration observed. The dorsal surface of the carapace was orange, with red tubercles on the gastric area and whitish tubercles on the cardiac and intestinal areas. Legs were pale pinkish-white. DNA barcodes. There are not 16 S sequences available for this species in Genbank, and thus, the four sequences (two haplotypes, differing in one position) of the specimens from MZ 08 and MZ 09 are the first ones for this species. There is only one COI sequence deposited in BOLD (MDECA 231 - 10), corresponding to a specimen of T. pustulosus collected in Mozambique, by the MB-exp in 2009 (date collection: 2009 - 04 - 09) deposited at the MNHN (MNHN-IU 200812672). The COI sequences of three specimens from MZ 08 and MZ 09 represent three different haplotypes (varying in one-two positions), fitting 99 % with the BOLD sequence (varying in three to five positions).

According to Galil (2003 b), Euclosiana exquisita is known only from the typelocation, Madagascar, at 185 – 314 m depth. Results and remarks. Only one female was collected in M 08 at 217 m depth. This specimen agrees well with the descriptions and figures by Galil (2003 b). E. exquisita has not been reported in the area before and therefore our specimen is the first record of the species in Mozambican waters. After the MOZAMBIQUE surveys, some specimens were collected in the MB-exp in 2009 (MNHN Collection). Colouration observed. Carapace and chelipeds were reddish brown, with three bright orange circles on each gastric region, being the median circle the largest. The anterior third of carapace is coarsely pitted. There were two very pale and poorly marked circles on the cardiac region, and a couple of faint lines on the middle of the intestinal region that remain after preservation, none of them described by Galil (2003 b). The granules of the chelipeds were white, and the legs with orange and white bands. The ventral side was white. After preservation in ethanol, the carapace and chelipeds turned to brown, and the circles and legs to bone colour. DNA barcodes. There are not 16 S sequences available for this species in Genbank, being this the first one. There is only one COI sequence deposited in BOLD (MDECA 222 - 10), corresponding to one specimen identified as Leucosia sp. by Chan, that was collected in Mozambique by the MB-exp in 2009 (date collection: 2009 - 04 - 09), and deposited at the MNHN (MNHN-IU 200812661). The COI sequence of the female IEO-CD-MZ 08 / 1757 fits 99.68 % with the BOLD sequence (differing in two mutations). Therefore, the specimen MNHN-IU 200812661 identified as Leucosia sp. must be considered to be Euclosiana exquisita. In Genbank there are sequences of 16 S and COI for Euclosiana crosnieri, E. scitula, and E. unidentata, deposited by Shi et al. (2020). The distances with Euclosiana exquisita are the expected for congeneric species: 16 S (98 %, five mutations) and COI (94 %, 35 mutations). However, the high divergence of E. crosnieri and E. scitula respect to E. unidentata (16 S, 96.8 %, 12 mutations - including three gaps - and COI, 87 %, 86 mutations) suggests an intergeneric distance. It must be pointed out that E. crosnieri and E. scitula could be synonyms, as they present exactly the same 16 S and COI sequences.

Following the key for Oxypleurodon of the IP (Guinot & Richer de Forges 1984), these seven specimens could be identified as O. difficilis but there are certain characters that are not coincident with the original description. Guinot & Richer de Forges (1984) described the intraspecific variability in the shape and size of the rostrum. According to them, juvenile males are similar to females in presenting a shorter and thicker rostrum than males. However, the adult males of O. difficilis IEO-CD-MZ 08 / 1774 and IEO-CD-MZ 08 / 1897 present short rostrum, and oppositely, the females IEO-CD-MZ 09 / 1823 - 0 a and IEO-CD-MZ 09 / 1823 - 2 bear elongated rostrum. In some specimens, the rostra are straight and in others curved upwards. In relation to the size of the channels between dorsal plates, Guinot & Richer de Forges (1984) described wider channels in the juvenile males, but this is also a variable feature in our specimens. Therefore, more similar to O. aurorae respect to this character. In addition, Guinot & Richer de Forges (1984) described the cardiac plates of O. difficilis as: “ always transversely oval-shaped ”. However, our specimens show great variability in the shape of this plate, from laterally elongated (upward or downward) to inverted triangleshaped (see Figure 10). Colouration observed. The specimens had a salmon-pink carapace, rostrum dark orange and plates of the dorsal surface white; 4 th- 5 th ambulatory legs white, and the chelipeds and 2 nd and 3 th legs salmon-pink, with propodus and dactyls clearly marked. Legs colour of O. difficilis described by Richer de Forges (2018) was merely white. DNA barcodes. There are not 16 S and COI sequences available for this species in Genbank or BOLD. The four equal sequences of 16 S obtained for four specimens from MZ 08 and MZ 09 are the first ones for this species. There are two COI sequences deposited in BOLD (MDECA 111 - 10 and MDECA 112 - 10), corresponding to two specimens of O. stuckiae collected in New Caledonia by Bouchet & Richer de Forges (date of collection: 1993 - 01 - 26), and deposited at the MNHN (MNHN-IU 200812259 and MNHN-IU 200812261). However, these sequences actually correspond to an unidentified Heterocarpus sp. according to the tree generated in BOLD and to the result of a BLAST search of these sequences in Genbank. The COI sequences obtained for four specimens of O. difficilis present only two haplotypes (differing in two positions). In a BLAST search, the maximum fit was 96 % with the sequences of three Plesionaka curvata, and the rest of matches (<90 %) were with several majoid species. The sequences of P. curvata that were uploaded at Genbank (JX 681746, JX 681749, JX 681750) by Zuccon et al. (2012) belong to specimens deposited in the MNHN (MNHN-IU 200814409, MNHN-IU- 2008 - 14410, MNHN-IU- 2008 - 14412), which were also uploaded to BOLD (MDECA 782 - 12, MDECA 786 - 12, MDECA 789 - 12), with other sequences of P. curvata that do belong to this species. Therefore, it seems that these three “ strange sequences ” of P. curvata could correspond to COI sequences of O. stuckiae since they fit 96 % (22 mutations) with the sequences of O. difficilis, being in the expected range of intrageneric variability. Therefore, sequences of an unidentified Heterocarpus sp. were deposited instead of the sequences of O. stuckiae while the right sequences of O. stuckiae were deposited under the name of Plesionaka curvata.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Naxioides robillardi is distributed throughout the IWP: Gulf of Oman, East Africa (Kenya, Somalia), Madagascar, Reunion Island, Mauritius, Solomon, Indonesia, Hong Kong, Philippines, Australia, Japan (Poupin, 1995) and recently reported from Korea (Lee et al. 2020). It inhabits hard bottoms between 30 and 260 m (Poupin 1995). Naxioides hirtus A. Milne-Edwards was the only species of Naxioides previously reported in Mozambican waters (Barnard 1950; Kensley 1981).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

03D487F82138FFFDFF71DC46B970F954.taxon	discussion	Remarks. The keys and descriptions used for the identification of this specimen were Griffin & Tranter (1986 a), Miers (1886) and Poupin (1995). Poupin (1995) distinguished two forms of this species: N. robillardi forma t ypica, and N. robillardi forma mammillata, our specimen being coincident with the first. It should be noted that we collected one single female specimen in M 07, at 620 m depth. The absence of other specimens and the fact that the only one was lacking the chelipeds, made not possible to confirm all the characteristics used for distinguishing both forms. The present specimen is the first record of N. robillardi in Mozambican waters, extending the maximum depth reported for this species up to 620 m. Colouration observed. The carapace was beige and it is covered in short dense yellowish-brown pubescence, with purplish-red spines, similar to that described by Miers (1882). Ambulatory legs were purplish-red, with subtle light and dark bands, almost imperceptible. After preservation in formalin the specimen acquired a homogeneous bone colour, without traces of the purplish-red colour, contrary to the permanence of violet areas in merus and carpus of the ambulatory legs described by Poupin (1995) after preservation in ethanol. DNA barcodes. There are not 16 S sequences available for this species in Genbank, this being the first one. There are three equal COI sequences in Genbank (MT 469872, MT 469873, MT 469874) obtained by Lee et al. (2020) from one specimen of N. robillardi from Korea. However, no COI sequence could be reared from the specimen IEO-CD-MZ 07 / 1892 from MZ 07 and therefore, comparison is not possible.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

M 09, Stn. 8, 648 m, ♂ 15.5 × 16.7 mm (IEO-CD-MZ 09 / 1802 - 1), 16 S (MZ 424947), COI (MZ 434792); ♀ ov. 9.5 × 11.5 mm (IEO-CD-MZ 09 / 1802 - 2), 16 S (MZ 424948), COI (MZ 434792). Habitat and distribution. Samadinia galathea was described by Griffin & Tranter (1986) as Rochinia galathea, from a male collected off Natal (South Africa) in 1951. This was the only existing record and thus, its distribution was limited to the topotypical locality, off Natal between 535 and 610 m depth (Griffin & Tranter 1986). Results and remarks. Our specimens agree well with the descriptions and figures of Griffin & Tranter (1986) and Richer de Forges & Ng (2013). Two individuals, one male and one ovigerous female were collected at the same station at 648 m, in March 2009 (MZ 09). This is the first record of S. galathea in waters of Mozambique, the second record worldwide and it extends the maximum depth reported for this species up to the 648 m. In addition, it is the first time that a female of this species is recorded, allowing the description of the female morphology, that differs somewhat to the described morphology of males. In the female, the mesogastric region is very inflated, “ hump ” - type, and the hepatic lobes are flattened and directed upwards (see Figure 11) while they curve backwards in the case of the male. The female was ovigerous, indicating that March was within the spawning season of this species in the area. Colouration observed. The carapace was white, with some pinkish areas. The hepatic lobes and intestinal area were dark orange, the chelipeds orange and the ambulatory legs white with pinkish merus. DNA barcodes. There are not 16 S sequences available for this species or close relatives in Genbank. These equal 16 S sequences of the male and female specimens are the first ones and confirm that the two specimens, despite their clear morphological differences, belong to the same species. There is one COI sequence deposited in BOLD (MDECA 051 - 10), corresponding to one specimen identified by Chan as Rochinia sp., collected in Mozambique by the MB-exp in 2009 (date collection: 2009 - 04 - 09) and deposited at the MNHN (MNHN _ IU 200810334), that fits 100 % with the two equal COI sequences of the male and female of S. galathea. There is also a second COI sequence deposited in BOLD (MDECA 724 - 10) corresponding to one specimen identified by Chan as Epialtidae sp. and collected in Madagascar, that fits 99.39 % (four mutations) with S. galathea, this being the distance expected at intraspecific level in a COI sequence. Therefore, both specimens, Rochinia sp. and Epialtidae sp., would correspond to S. galathea.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. IWP from east Africa to Philippines and Japan (Griffin & Tranter 1986). It was recorded in waters of Mozambique by Richer de Forges & Ng (2013) at 355 – 636 m depth. Results and remarks. The specimens examined conform to the description made by Griffin & Tranter (1986). The ten specimens studied were collected during M 07, M 08 and M 09, between 457 and 628 m depth. This is the second published record of Samadinia pulchra off Mozambique, although according to the collection date, our specimens from 2007 and 2008 surveys represent the firsts collected in these waters. The species was reported as Rochinia pulchra by Richer de Forges & Ng (2013) from the MB-exp in 2009. The specimens reviewed here differ in the length and morphology of the rostrum, as it was already observed by Richer de Forges & Ng (2013). There are specimens with the rostral spines very curved downwards, while others have them almost straight. The same occurs with the opening angle between both rostral spines, exceptionally long and outwards curved in some specimens. Apart from the shape differences observed in the rostrum, we have also found differences between the lengths of the pseudo-thorn spines of the studied individuals (see Figure 12). Colouration observed. The body was whitish, with orange carapace spines, rostral spines and chelipeds and pink ambulatory legs. DNA barcodes. There are not 16 S sequences available for this species or close relatives in Genbank. These equal three 16 S sequences of the two males and one female are the first ones and differ in 13 mutations from the 16 S sequences of S. galathea (97.5 % similarity), in the expected interspecific range. The three specimens present the same COI haplotype, that fit 100 % with one COI sequence deposited in BOLD (MDECA 049 - 10), corresponding to a specimen identified by Chan as Rochinia sp., collected in Mozambique by the MB-exp in 2009 (date collection: 2009 - 04 - 09) and deposited at the MNHN (MNHN _ IU 200810330). According to these new data, this record must be attributed to S. pulchra.

Habitat and distribution. This species is distributed in Madagascar, Nicobar Island and Indonesia (Guinot & Richer de Forges 1982 a). Results and remarks. The specimens were identified following the key of Guinot & Richer de Forges (1982 a, b, 1984, 1986). Four specimens of Cyrtomaia gaillardi were studied, that had been collected during the three surveys (M 07, M 08 and M 09), at depths between 529 and 631 m. Although this species was recorded off Madagascar (Guinot & Richer de Forges 1982 a), it is not registered in any checklist of the area (WIO) (Barnard, 1950; Emmerson 2016 b, c; Kensley 1981; Poupin 2010, 2018), being C. murrayi Miers the only species of this genus cited in the area. Therefore, these specimens are the first record of C. gaillardi in Mozambique waters. Subsequently, in April 2009, one specimen was collected during the MB-exp (GBIF. org 2021, unpublished record). Colouration observed. Specimens were light orange, with whitish finger tips, dactylus and proximal region of the merus. DNA barcodes. There are not 16 S sequences available for this genus in Genbank, except for a short sequence of 164 bp of Cyrtomaia owstoni deposited by Komai et al. (2019) that fits 100 % with the 16 S sequence (552 bp) of C. gaillardi. Considering the short length of the sequence and the low number of mutations expected at congeneric level nothing could be concluded. According to Guinot & Richer de Forges (1982 a), C. owstoni has long branchial spines, these being the longest of the dorsal side of carapace, while protogastric spines are the longest in C. gaillardi. These clear morpholofical features make it difficult to confuse both species. Unfortunately, not COI sequence was obtained, although in any case there is not any COI sequence available in Genbank or BOLD for comparison.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

M 07, Stn. 1,449 m, ♀ 53.8 × 53.9 mm; ♂ 68.2 × 68.2 mm (IEO-CD-MZ 07 / 1920), 16 S (MZ 424953), COI (MZ 434797); M 08, Stn. 68, 244 m, ♂ (IEO-CD-MZ 08 / 1789); M 09, Stn. 19, 542 m, ♂ 84.2 × 73.5 mm (IEO-CD-MZ 09 / 1854 - 2), 16 S (MZ 424954), COI (MZ 434798). Habitat and distribution. This species has an IP distribution, Andaman Sea, Great Nicobar, East African coast (Griffin & Trander 1986), East China Sea and Hong Kong (Sasaki 2019) and has been cited by Emmerson (2016 c) in Mozambican waters, between 210 – 655 m. Results and remarks. The four studied specimens of Platymaia alcocki were collected in M 07 and M 09, at depths between 449 and 542 m. The specimens were identified following Guinot & Richer de Forges (1986) and Griffin & Tranter (1986 a, b). Although P. alcocki and P. wyvillethomsoni Miers were confused in the past, some features described mainly by Griffin & Tranter (1986 a) allowed us to confirm the identification of our specimens as P. alcocki, among them: similar length of the interantennular spines in relation to the rostral spines; rostral spines curved inward; margins of the supraorbital eave gently tuberculated in males and sharply tuberculated and swollen in females; gastric regions strongly elevated and protogastric ridges tuberculated without spines; and apex of the tip of the first pleopod of the male curved up. Colouration observed. Colour of carapace and legs bright orange, with some white parts as tips of quelipeds, dactyli and spines, basi-ischium and deeper areas of carapace. DNA barcodes: There are not 16 S sequences available for this species in Genbank. There is only a short (400 bp) and incomplete 16 S sequence of Platymaia remifera, deposited in Genbank by Tsang et al. (2014) that probably correspond with the version of the sequence after alignment and removal of hypervariable positions, for example after application of GBlocks. Therefore, it is not possible a real comparison without the complete sequence. There is a COI sequence (MDECA 062 - 10) in BOLD, corresponding to a specimen identified by Chan as Platymaia sp. that was collected in Mozambique by the MB-exp in 2009 (date collection: 2009 - 04 - 09) and deposited at the MNHN (MNHN _ IU 200810370). However, the COI haplotype of the two specimens of P. alcocki present a similarity of 83.5 % respect to that of Platymaia sp., representing distances expected at intergeneric level.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Platymaia turbynei is distributed along the east coast of South Africa, from Natal to southern Mozambique Channel, Madagascar, and Reunion Island (Griffin & Tranter 1986), between 200 and 880 m (according to Kensley 1981) or 996 m (according to Emmerson 2016 c) in Mozambican waters. Results and remarks. The six specimens were collected between March and April of M 07, M 08 and M 09, at depths of 542 – 620 m. Their morphological characters are in agreement with the descriptions included in the revision of some majoid crabs of IWP made by Griffin & Tranter (1986). Colouration observed. Fresh specimens showed reddish carapace and salmon-colour legs. The spines are darker. DNA barcodes. As already commented above for the 16 S sequence of P. alcocki, there are not 16 S sequences available for this species on any public database. There is only a short (400 bp) and incomplete 16 S sequence of Platymaia remifera, deposited in Genbank by Tsang et al. (2014). Therefore, it is not possible a real comparison without the complete sequence, but the 15 mutations found in the 400 bp suggest a distance that fits well at intrageneric level. When comparing with the 16 S sequence of P. alcocki, the similarity found of 91 % could be considered in the limit between intra or intergeneric distance. This distance increased when comparing the COI sequences, with a similarity of 83 %, that also supports a divergence at intergeneric level. There is a COI sequence (MDECA 062 - 10) in BOLD that corresponds to one specimen identified by Chan as Platymaia sp. which was collected in Mozambique by the MB-exp in 2009 (date collection: 2009 - 04 - 09) and deposited at the MNHN (MNHN _ IU 200810370). This COI sequence fits 99.67 and 99.02 % (one and seven mutations, respectively) with the two COI haplotypes obtained for P. turbynei, and for this reason it must be attributed to this species.

Habitat and distribution. Majidae is constantly under review. In 2015, Ng and Richer de Forges described seven new genera to separate the species that were included within Maja Lamarck, 1801 until that moment. In this study Maja gibba was replaced in Paramaja, a genus described by Kubo in 1936. Paramaja gibba is close to Paramaja kominatoensis Kubo, a commonly mistaken and misidentified species. Paramaja gibba is distributed from the IWP, Madagascar (Mozambique Channel), India, Thailand to Western Australia (Ng & Richer de Forges 2015), and Japan (Sakai 1976), at 230 – 600 m depth. Results and remarks. These specimens agree well with the descriptions and figures of Ng & Richer de Forges (2015): “ in adults, pseudorostral horns dorso-ventrally flattened; carapace dorsal surface relatively less swollen, with numerous small and large distinct tubercles and granules which are never swollen ”. The five studied specimens were collected during the M 07, M 08 and M 09 surveys, at depths from 243 to 378 m. These are the first record of P. gibba off Mozambique. Subsequently, in April 2009, two specimens were collected during the MB-exp (GBIF. org 2021, unpublished record). Colouration observed. The specimens were bright orange with darker sunken areas and clearest lateral areas; legs were bone-colour although they seem to be brown due to fouling attached to them, as they were very hairy. Chelipeds were pale orange, with white finger tips. After preservation, both in ethanol and formalin, carapace and chelipeds turned to pale bone colour, while legs keep the brown-like colour due to the fouling. DNA barcodes. There are not 16 S and COI sequences available for this species on any public database. The three sequences obtained for 16 S represent three different haplotypes, differing in one and two mutations, and they are the first 16 S sequences for this species. One of these haplotypes belonging to the female IEO-CD-MZ 09 / 1820 matches 100 % with a 16 S sequence (GQ 153568) of P. kominatoensis (as Maja kominatoensis), obtained by Sotelo et al. (2009) from one specimen from Philippines. Similarly, in the case of COI, the three specimens present three different haplotypes, two of them differ only in one position, and another one that vary in three and four mutations. The COI sequence of the male IEO-CD-MZ 09 / 1800 also matches 100 % with two sequences (MG 029415, KX 757758) of two specimens of P. kominatoensis (as Maja kominatoensis) from India uploaded to Genbank by Deepak et al. (unpublished), and 99 % with the COI sequence (GQ 153558) of P. kominatoensis (as Maja kominatoensis) from Philippines (Sotelo et al. 2009). These data from 16 S and COI barcodes put into question the validity of both species as separate taxa and support the suggestion by Griffin & Tranter (1986) that they may be synonymous. Therefore, a review of these two species (P. gibba and P. kominatoensis), including more specimens and more molecular data (also nuclear genes), is needed to clarify their taxonomic relationships and distributions.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Pleistacantha ori had been misidentified and confused with Pleistacantha moseleyi (Miers) for many years, until it was described by Ahyong & Ng (2007) as a new species. It is presently known from off the Natal coast, South Africa, and Madagascar, between 238 and 480 m depth (Ahyong & Ng 2007). It was cited by Emmerson (2016 c) in waters of Mozambique. Results and remarks. Several different keys and descriptions were used to identify our specimens: Ahyong & Ng (2007), Griffin (1974), Griffin & Tranter (1986) and Ng e t al. (2017). This was due to the difficult identification of this species because the different sizes of the studied specimens, the common morphological variability between adults and juveniles and the high variability in the size and morphology of the spines found between specimens. Genetic was used to confirm that the smallest specimens analysed belong to the same species than the adults. Eleven specimens, collected between 2007 and 2009, at depths between 258 and 623 m, were studied. Our records extend the depth range from 480 to 623 m for this species in its complete geographical distribution. Colouration observed. Our specimens had white carapace, being dark orange in the most prominent zones of the branchial, gastric and cardiac regions. The pseudo-spines were orange, with white tips. The pleon was basically white. The ambulatory legs were whitish orange with long longitudinal spots on merus and carpus, while dactyli looks brown due to the dense tomentum and fouling on them. Smallest individuals had orange carapace with fewer white areas, white legs with many orange transverse stripes and white dactylus, with no fouling on them. DNA barcodes. There are not 16 S and COI sequences available for this species on any public database. Therefore, these are the firsts 16 S and COI sequences obtained for this species. The six sequences obtained for 16 S belong to a unique haplotype. The BLAST search matches 96.5 % (intrageneric distance) with Pleistacantha kannu (MH 384947) from India, submitted by Ravichandran et al. (unpublished), the only species of this genus with a valid sequence in Genbank. There is a sequence of Pleistacantha sanctijohannis (LC 430736) deposited by Komai et al. (2019), but it is noticeably short s (only 164 bp) and does not allow any accurate comparison. Respect to COI, the five sequences obtained for P. ori represent four different haplotypes (differing in one, two and five positions), and the only COI sequence of the genus in Genbank, Pleistacantha kannu (MH 425628) from India, does not match, and look like a bacterial sequence. Superfamily PORTUNOIDEA Rafinesque, 1815 According partially to WoRMS (2021) and following the last and more recent review by Spiridonov (2020), this superfamily comprises four families, Brusiniidae Števćić, Carcinidae MacLeay, Geryonidae Colosi, and Portunidae Rafinesque.

Philippines, Indonesia, Admiralty Islands, at a depth range of 107 – 274 m (Crosnier 2002). Results and remarks. Only one female specimen was collected in M 08 at 265 m depth. This specimen agrees well with the descriptions and figures in Crosnier (2002). This is the first record of P. granosus off Mozambique. Colouration observed. No pictures are available. DNA barcodes. There is only a short (400 bp) and incomplete 16 S sequence for this genus in Genbank belonging to P. orientalis (Miers) deposited by Tsang et al. (2014). This corresponds probably to the version of the sequence after alignment and removal of hypervariable positions, for example after application of GBlocks, as mentioned above for other species in the same work. Although a robust comparison is not possible without the complete 16 S sequence, the 11 mutations found in the 400 bp in relation to the 511 bp of the 16 S sequence of the female IEO-CD-MZ 08 / 1785 suggest a distance that fits well at interspecific level. There are not COI sequences of this species on any public database, but the BOLD search shows 88.61 to 95.16 % of similarity with other species of this genus as P. tuberosus Crosnier, P. intermedius Crosnier, and P. orientalis.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Chaceon macphersoni occurs at depths between 293 and 900 m (Emmerson 2016 c) and up to 1025 m (Groenevel et al. 2013), in the WIO, off Mozambique, southern Madagascar and eastern South Africa, and extends westwards up to Cape Columbine along the Atlantic coast of South Africa (Groenevel et al. 2013; Emmerson 2016 c). Catches of C. macphersoni made off eastern South Africa and Mozambique were attributed to Chaceon quinquedens (Smith) (as Geryon quinquedens) up to 1989, when the family Geryonidae was revised, the new genus Chaceon erected, and C. macphersoni was described (Manning & Holthuis 1988, 1989). This species constitutes an important retained by-catch in multispecies crustacean trawl fisheries and deep-water trap fisheries for spiny lobsters off southern Mozambique (Paula & Silva 1985). Results and remarks. Our specimens agree well with the descriptions and figures of Manning & Holthuis (1989). Seven specimens were collected during the three surveys (M 07, M 08 and M 09) between 548 and 685 m depth. Colouration observed. The carapace was dorsally yellowish, splashed of small white spots around the branchial and protogastric areas, and with white edges. Chelipeds were pinkish, almost white, and the legs have light pink merus and carpus, and maroon propodus and dactylus. DNA barcodes. The 16 S sequences of three specimens represent two haplotypes (differing in two positions). There are not 16 S sequences of this species in Genbank, being these the first ones for this species. The closer matches are with Chaceon maritae (LN 809920) obtained by Hernández et al.

Respect to COI, the four sequences obtained for C. macphersoni represent four different haplotypes (differing in two-three positions), that fit 99.2 – 99.68 % of similarity with four sequences of C. macphersoni from South Africa available in BOLD as “ private ”, and therefore with no access to the sequences and no more data available for comparison. Subfamily OVALIPIINAE Spiridonov, Neretina & Schepetov, 2014 The subfamily Ovalipiinae was described as family Ovalipidae by Spirodonov et al. (2014). However, Spirodonov (2020), in agreement with the suggestion by Evans (2018) based on his molecular phylogenetic reconstruction, accepted the closer relationships of Ovalipes with geryonids and consequently moved this group as a subfamily of the Geryonidae with only one genus. They are pelagic species known as swimming crabs (Kensley 1981).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. Chaceon macphersoni occurs at depths between 293 and 900 m (Emmerson 2016 c) and up to 1025 m (Groenevel et al. 2013), in the WIO, off Mozambique, southern Madagascar and eastern South Africa, and extends westwards up to Cape Columbine along the Atlantic coast of South Africa (Groenevel et al. 2013; Emmerson 2016 c). Catches of C. macphersoni made off eastern South Africa and Mozambique were attributed to Chaceon quinquedens (Smith) (as Geryon quinquedens) up to 1989, when the family Geryonidae was revised, the new genus Chaceon erected, and C. macphersoni was described (Manning & Holthuis 1988, 1989). This species constitutes an important retained by-catch in multispecies crustacean trawl fisheries and deep-water trap fisheries for spiny lobsters off southern Mozambique (Paula & Silva 1985).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Habitat and distribution. This species is distributed in the IP: Indonesia, Australia, Japan, and South Africa (Stephenson & Rees 1968), Mozambique (Kensley 1981) and New Caledonia (Poupin 2010), mainly at deep waters (Stephenson & Rees 1968), between 80 and 400 m (Emmerson 2016 c). Results and remarks. Ovalipes iridescens specimens were revised following the descriptions of Stepheson & Rees (1968). These specimens were collected between 375 and 449 m depth, in the central and southern areas off Mozambique, during the three surveys (M 07, M 08, M 09), and these records extend the maximum depth from 400 up to 449 m. Colouration observed. The specimen was bright orange colour with certain iridescence and with some whitish areas in the posterior half of the carapace. The cardiac, branchial, and gastric regions of the carapace were dark orange, with two lighter oval spots on both sides of the cardiac region. The hepatic area was whitish, with a row of highly accentuated crescent-shaped white dots. Chelipeds were orange, with a large iridescent stain on the merus and white fingers. Ambulatory legs had whitish merus, orange carpus and propodus and orange-brown dactylus. The ventral area of the individual was white. After preservation, in both ethanol and formalin, the specimen turned bone-coloured, keeping the iridescence on certain areas of the carapace and merus. DNA barcodes. There is a COI sequence for O. iridescens in BOLD (MDECA 151 - 10) from a specimen collected in Indonesia (MNHN IU- 200812533) (date of collection: 1991 - 19 - 21) identified by Moosa, that only fits 93.57 % (39 mutations) with the COI sequence of the specimen IEO-CD-MZ 09 / 1809. However, there is one sequence in BOLD of Ovalipes sp. (MDECA 064 - 10), corresponding to one specimen identified by Chan, that was collected in Mozambique during the MB-exp in 2009 (date collection: 2009 - 04 - 09) and deposited at the MNHN (MNHN IU 200810370). This sequence fits 97.85 % (13 mutations) with ours, being in the limit between inter or intraspecific variability. Family PORTUNIDAE Rafinesque, 1815 Portunidae is a large family comprising seven subfamilies and 36 genera according to the recent update by Spirodonov (2020). It has been relatively well studied in recent years, based both on morphological analysis and molecular phylogenies (De Grave et al. 2009; Evans 2018, Karasawa et al. 2008; Mantelatto et al. 2018; Schubart & Reuschel 2009; Schweitzer et al. 2010; Spiridonov et al. 2014) and consequently subject of many recent changes. According to Emmerson (2016 c), only two subfamilies occur in Mozambique, Portuninae Rafinesque and Thalamitinae Paulson, because he considered Scylla not in the new subfamily Necronectinae Glaessner but in Portuninae.

Habitat and distribution. Scylla serrata is a common species in the IP, included in all the IWP checklists (Crosnier 1962; Kensley 1981; Poupin 2010, 2018; Emmerson 2016 c). It is distributed along the coasts of East South Africa (South Africa, Mozambique, Somalia, Madagascar), Australia and Japan (Crosnier, 1962). According to Keenan et al. (1998), S. serrata is the most widespread species within the genus. It is a coastal species, even intertidal (Stephenson 1972), which uses estuaries and mangroves as nurseries, as it is the case of the Saco mangrove creek, on Inhaca Island (South Mozambique) (Paula et al. 2004). Although the species is associated with mangroves that are flooded with ocean water during most of the year, it can also tolerate reduced salinities (Keenan et al. 1998). Results and remarks. The unique specimen was determined using the key and illustrations of Crosnier (1962) and Apel & Spiridonov (1998). It is a large individual collected in M 08 at 235 m depth. Poupin (2010) and Emmerson (2016 c) reported this species in brackish waters of intertidal areas. Therefore, this new record extends the bathymetric range of S. serrata to deep waters up to 235 m. The specimen was collected in front of the Quelimane estuary in Mozambique, which might be a nursery area for this species, while adults might migrate towards deeper waters. Colouration observed. Photographs of the live specimen are not available. DNA barcodes. The 16 S sequence of the specimen IEO-CD-MOZ 08 / 2238 fits 100 % with several sequences of Scylla serrata deposited in Genbank.

Habitat and distribution. Charybdis (Gonioneptunus) africana occurs between 48 and 126 m, off South Africa (Barnard 1950; Shen 1935) and Mozambique (Kensley 1981). Results and remarks. These specimens were identified at genus level following Crosnier (1962), at subgenus level following Leene (1938) and at species level following Shen (1935) and Barnard (1950). A total of eight individuals were collected during the three surveys (M 07, M 08 and M 09), at depths between 184 and 322 m. This is the second record in Mozambican waters, which expands the species depth range from 126 up to 322 m. Charybdis africana and Charybdis bimaculata have been considered synonyms (Sakai 1939), although WoRMS currently considers them as valid species. The similarity between the characters used by Shen (1935) and Barnard (1950) to separate both species might have justified that they were considered synonyms by Sakai (1939). However, Shen (1935) established differences in the relationship CW / CL, this being 1.46 for C. africana and 1.55 for C. bimaculata. Considering this as a distinctive character for both species, our specimens with CW / CL ratios between 1.42 - 1.47 are closer to C. africana. The tip shape of G 1 could be a distinctive character between the species, only described so far for C. bimaculata (Leene 1938) but not for C. africana. The G 1 shapes of the specimens (all males) are similar to those described for C. bimaculata, although their tips are more elongated and pointed (see Figure 15 B). Colouration observed. The common name of C. bimaculata, “ two-spot swimming crab ”, makes reference to the two spots located on the mesobranchial region of the carapace. No information on the presence or absence of these spots on C. africana is available. These eight specimens also had two spots, although they were not as remarkable as observed in the images available of C. bimaculata. Our specimens showed a white spot on the cardiac region of the carapace, which was also observed in the images of C. bimaculata, although in this case they were much more elongated, even reaching the edge of the carapace. General colouration was also different as C. bimaculata is brown and beige colour, marble-like, while our specimens had a reddish-brown carapace with red granules. Legs and chelae were beige, with very scattered red granules, with bigger size and presence on the chelae. Dactyli were yellowish dorsally and white ventrally. DNA barcodes. The three 16 S sequences present only one haplotype that fits 99.22 – 99.41 % (three – four mutations) with four sequences of C. bimaculata from Taiwan (KX 060391), South Korea (MG 787408, NC _ 037695), and Vanuatu (KT 365596), deposited at Genbank by Negri et al. (2018), Liu et al. (2018), Kim et al (2018) and Evans (2018), respectively. The three different haplotypes found for COI sequences, differ in 11 – 12 mutations respect to several COI sequences of C. bimaculata (similarity ranging from 97.47 to 98.25 %). As occurs for Ovalipes iridescens, these values fall just in the limit between inter or intraspecific variability.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Widely distributed in the IWP from South and East Africa through the Gulf of Oman, the Arabian Gulf, Pakistan, India, Sri Lanka to Indonesia, Singapore, Australia, Vietnam, China, and Japan (Apel & Spiridonov 1998). Crosnier (1962) described the distribution of the synonym species Charybdis cruciate (Herbst) in shallow waters of South Africa, Australia, and Japan, at 5 - 15 m (rarely 30 m). Not being recorded in Mozambique since the fifties of last century (Barnard 1950), it has been recently reported by personal observations of IIP-Mozambique. Results and remarks. The single specimen agrees well with the description and figures in Crosnier (1962) and Apel & Spiridonov (1998). It was collected in March 2007 (M 07) at 138 m depth, increasing the previously reported bathymetric distribution of the species. Colouration observed. No pictures of the fresh specimen are available. DNA barcodes. Only the COI sequence could be obtained from this specimen, which represents a new haplotype for this species. The closer haplotype is a COI sequence of a specimen from Australia (MN 184690), with differences in two positions (99.68 % similarity), ranging between 98.65 to 97.30 % of similarity (seven to 14 mutations) with respect to the rest of 60 haplotypes for this species in Genbank.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

M 08, Stn. 76, 222 m, ♂ 64 × 44.6 mm (IEO-CD-MZ 08 / 1794 - 1), 16 S (MZ 424974), COI (MZ 434822); ♂ 58 × 40.7 mm (IEO-CD-MZ 08 / 1794 - 2), 16 S (MZ 424975), COI (MZ 434822). Habitat and distribution. Charybdis smithii is a semi-pelagic species that spends a considerable part of its life in the water column (Turkay & Spiridonov 2006), extending its pelagic habitat from the mixed layer to upper mesopelagic waters (Romanov et al. 2009) at depths between 60 and 450 m. It is distributed along the western and northern Indian Ocean, from off South Africa, Madagascar, Somalia, Seychelles, Maldives, Saya de Malha, Gulf of Aden, Red Sea, Bay of Bengal (Apel & Spiridonov 1998; Turkey & Spiridonov 2006), although most of the crabs are found in the western basin of the Indian Ocean (Romanov et al. 2008). C. smithii is common in the pelagic provinces of the western Indian Ocean, where they are driven to, by the wind monsoon regime. Based on the nutritive value determined for this species, Kumar et al. (2019) raised the possibility of its potential exploitation as a commercial resource. Results and remarks. These two male specimens agree well with the descriptions and figures in Apel & Spiridonov (1998) and Turkey & Spiridonov (2006). They were collected during the 2008 survey at 222 m depth. This is the first record of C. smithii off Mozambique. Ng & Takeda (1999) reported that two closely allied species, C. smithii and Charybdis omanensis, differ in many morphometric and gonopodal characters. Türkay & Spiridonov (2006) reviewed the deep-water species belonging to Charybdis subgenus Goniohellenus, and described a new subspecies, C. (G.) omanensis septentrionalis Türkay & Spiridonov, 2006 restricted to the central and southern Red Sea and further extended to the Arabian Sea and India (Josileen et al. 2018). The diagnostic characters used for the identification of our specimens as C. smithii instead the subspecies C. omanensis septentrionalis, based on Türkay & Spiridonov (2006) are: posterolateral angles of the carapace nearly rounded instead almost forming a right-angle, as described for C. omanensis septentrionalis (see Figure 16 A); the carapace not densely pilose and without the frontal patches of granules neither protogastrics areas with short bands of three – four lines of granules described for C. omanensis septentrionalis; tips of G 1 of the two males are not twisted downwards as they are for C. omanensis septentrionalis (Apel & Spiridonov 1998) (see Figures 16 B, C). Colouration observed. Both male specimens were reddish, with smooth carapace without granular patches, as described by Turkay & Spiridonov (2006). The tubercles on the chelipeds were dark red. Some irregular white spots were bordering the upper zone of the epibranchial region, with the shape of a semicircle. This colour pattern was not described by Apel & Spiridonov (1998) or Turkey & Spiridonov (2006). The finger tips were deep brown. After preservation in ethanol, the specimens turned to beige with some pinkish patches, the finger tips remaining brown. DNA barcodes. The 16 S and the COI sequences of the two specimens present the same haplotypes that fits 100 % with the 16 S and COI sequences of C. smithii (KX 060404, KX 060191) from the same specimen (MNHB 27685) from Oman (Negri et al. 2018). However, also de COI sequences fit 100 % with the three sequences of C. omanensis septentrionalis (KY 651228 - KY 651230) uploaded to Genbank by Josileen et al. (unpublished). Superfamily XANTHOIDEA Guinot, 1967 Family XANTHIDAE MacLeay, 1838 The Xanthidae is a broad family, which according to Davie et al. (2015 c), includes 129 genera and 629 species. Thirty of these genera are present in waters of Southern Africa (Serène 1984; Ng et al. 2008; Poupin 2010). The majority of xanthid species inhabit intertidal areas (Guinot & Macpherson 1988) and only two species have been cited by Emmerson (2016 c) in waters deeper than 100 m, Actaea savignii (H. Milne Edwards) and Gaillardiellus rueppelli (Krauss).	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.

Its distribution includes Reunion Island, the great bank Saya de Malha, South Africa and Angola, at 210 m (Guinot & Macpherson 1988), Mayotte Island (Poupin 2010, 2018), Mozambique (Emmerson 2016 c) and Australia (GBIF. org 2021, unpublished record). Results and remarks. The descriptions of Guinot & Macpherson (1988) and Serène (1984) were followed to identify the two male specimens. In one of the specimens (IEO-CD-MZ 09 / 1763) the spines on merus and carpus of P 2 – P 5 are not sharp. Both of them were collected in March (MZ 07 and MZ 09), at depths between 254 and 425 m, and thus, these records extend the maximum depth of the species to 425 m. Colouration observed. The carapace was orange with white edges and some small red and white tubercles. Chelae were orange with red tubercule tips, white palm and brown fingers. Meri of chelipeds had orange and white bands and carpi and dactyli were orange with red tubercules. DNA barcodes. The 16 S sequence fits 100 % with that of Monodaeus tuberculidens (HM 798515) obtained by Lai et al. (2011). However, it differs in only 1 mutation to two sequences of Monodaeus couchii (AM 076771 and HM 798510) by Reuschel & Schubart (2006) and Lai et al. (2011). The COI sequence is also close to one of M. tuberculidens (HM 751031), from the same specimen, also obtained by Lai et al. (2011), fitting 99.66 % (two mutations). Similarly to 16 S, in this case there are other 20 sequences of M. couchii presenting close haplotypes that vary in a range of five to eight mutations (98.66 to 99.21 %). Therefore, M. tuberculidens and M. couchii are closer species that need to be further studied to clarify their relationship.	en	Muñoz, Isabel, García-Isarch, Eva, Cuesta, Jose A.
