03AE8B60AC03FFDF6CC1FCAFFA2FC7FE.taxon	discussion	Remarks. Abyssorchomene is most similar to Koroga. Both genera have subchelate first gnathopods with a compressed carpus. However, Abyssorchomene has a moderately to deeply cleft telson (notched in Koroga). Both genera are scavengers with wide-spread distributions. D’Udekem d’Acoz & Havermans (2012) include A. plebs and A. rossi in the tryphosine genus Pseudorchomene Schellenberg, 1926 based on molecular evidence. Abyssorchomene plebs and A. rossi are morphologically dissimilar to P. coatsi (Chilton, 1912), the type species of Pseudorchomene, Schellenberg, 1926, but very similar to species usually assigned to Abyssorchomene. D’Udekem d’Acoz & Havermans (2012) did not test the molecular affinities of the other ten species of Abyssorchomene against Pseudorchomene before moving these species. Transferring A. rossi and A. plebs to Pseudorchomene confounds the morphological concept of both genera. Therefore based on the maxilla 1 setal-tooth arrangement and the morphology of the first gnathopods we prefer to retain these species within Abyssorchomene until such time as affinities of the entire Abyssorchomene / Pseudorchomene complex have been tested. Abyssorchomene abyssorum Stebbing, 1888, A. gerulicorbis (Shulenberger & Barnard, 1976) and A. scotianensis (Andres, 1983) are extremely similar morphologically. The only character difference we see is the first coxa which is rectangular in A. gerulicorbis and subtlety adze-shaped in A. scotianensis. We leave them as separate species for the moment. The species recorded as A. abyssorum by Barnard & Ingram, 1990 and by Birstein & Vinogradov, 1960 from the tropical Pacific Ocean look more similar to each other than either does to the A. abyssorum of Stebbing, 1888 from the south-western Atlantic.	en	Lowry, J.

03AE8B60AC01FFD06CC1FB51FC3BC2BC.taxon	discussion	Remarks. Abyssorchomene distinctus has a broadly rounded posteroventral corner on epimeron 3 such as A. charcoti, A. musculosus and A. nodimanus. Gnathopod 1 is subchelate in A. distinctus and A. musculosus (parachelate in A. charcoti and A. nodimanus). There is little difference between A. distinctus and A. musculosus. The palm of gnathopod 1 is slightly convex in A. distinctus (straight in A. musculosus) and the setal-teeth on maxilla 1 appear to be more slender, but this could be the angle of the illustration. In other respects they appear to be the same. Depth range. 2635 – 5173 m (Barnard & Ingram 1990, Jamieson et al. 2011).	en	Lowry, J. K., Kilgallen, N. M.

03AE8B60AC0EFFD16CC1FD96FAC4C2E4.taxon	discussion	Remarks. Abyssorchomene gerulicorbis has a subrectangular first coxa with a nearly straight anterior margin similar to A. abyssorum and A. charcoti. Abyssorchomene gerulicorbis and A. abyssorum have subchelate first gnathopods (parachelate in A. charcoti). It is difficult to separate A. gerulicorbis from A. abyssorum and A. scotianensis. Abyssorchomene gerulicorbis and A. abyssorum both have subrectangular first coxae (subtly adzeshaped in A. scotianensis). The inner plate of maxilla 2 is significantly shorter than the outer plate in the A. abyssorum of Barnard & Ingram (1990), but not in the specimen of Stebbing (1888) or to a less extent the specimen of Birstein & Vinogradov (1990). The adze-shaped first coxa separated A. scotianensis separates form these two species but in other characters they are extremely similar. Abyssorchomene gerulicorbis differs from A. chevreuxi mainly in the upper lip which is slightly produced and apically narrowly rounded (upper lip not produced in A. chevreuxi) and in A. gerulicorbis the dactylus of gnathopod 1 has a posterodistal ‘ setal basket’ (absent in A. chevreuxi).	en	Lowry, J.

03AE8B60AC17FFC96CC1FF2AFDA9C06F.taxon	discussion	Remarks. Eclecticus appears to be most similar to Nagada. They differ mainly in the gnathopod 1 dactylus (complex spines in Eclecticus and simple in Nagada). Ichnopus also has the dactylus of gnathopod 1 with complex spination but Ichnopus has a deeply cleft telson (entire in Eclecticus).	en	Lowry, J. K., Kilgallen, N. M.

03AE8B60AC17FFC96CC1FCFEFA28C485.taxon	discussion	Remarks. Euonyx appears to be the immediate sister taxon of Stephonyx Lowry & Stoddart, 1989. Euonyx has abandoned the scavenging life-style to become an ectoparasite of echinoids and in the process developed severely reduced mouthparts, particularly the seta-teeth of the maxilla 1 outer plate. In Euonyx coecus Pirlot, 1933 the setal-teeth of maxilla 1 appear to be intermediate between Euonyx and Stephonyx, but the mandibular molar is absent, an important characteristic of Euonyx.	en	Lowry, J.

03AE8B60AC26FFFD6CC1FF2AFDA8C054.taxon	description	Description. Based on female, approx. 10.0 mm, AM P. 69462. Head, lateral cephalic lobes broadly rounded; eyes reniform. Antenna 1 peduncular article 1 without anterodistal lobe; accessory flagellum 4 - articulate, terminal article not offset; primary flagellum with weak 2 - field callynophore; calceoli absent. Antenna 2 peduncular article 3 elongate, articles 3 to 5 not enlarged, brush setae present; flagellum short; calceoli absent. Labrum, epistome and upper lip separate; epistome produced equally with upper lip; upper lip not produced. Mandible incisors large, left and right symmetrical; molar setose, with a weakly spinose triturating area; palp attached slightly proximally, article 2 margins subparallel, article 3 blade-like. Maxilla 1 outer plate setal-tooth 7 present, cuspidate along most of inner; palp distal margin with apical robust setae, serrate at apicomedial corner. Maxilliped outer plate with 2 short, slender apical robust setae. Gnathopod 1 strongly subchelate; coxa large, about as long as coxa 2, subrectangular with concave anterior margin; basis sparsely setose along anterior margin; ischium short (length less than 2 × breadth); carpus compressed, shorter than propodus; propodus large, margins subparallel, palm transverse, entire, slightly concave; dactylus simple. Gnathopod 2 propodus palm moderately obtuse. Pereopod 4 coxa with a moderately developed posteroventral lobe. Pereopod 5 coxa without distinct lateral ridge; basis longer than broad, posterior margin not serrate. Pereopod 7 basis posterodistally produced less than halfway along merus. Pleonite 3 without mid-dorsal carina, not produced dorsodistally, posterodorsal margin not produced. Epimeron 3 posterior margin smooth, posteroventral corner narrowly rounded. Urosomite 1 not projecting over urosomite 2, with rounded boss. Uropod 2 inner ramus without constriction. Uropod 3 peduncle without dorsolateral flange; outer ramus article 2 short, with plumose setae on both rami. Telson notched, without dorsal robust setae, with 1 apical robust setae on each lobe. Sexually dimorphic characters. Based on male, 8.7 mm, AM P. 69463. Antenna 1 primary flagellum with strong 2 - field callynophore; calceoli present. Antenna 2 flagellum short; calceoli present. Depth range. Depths given in the literature range from 0 – 9120 m (Birstein & Vinogradov 1960), however, as these records represent specimens taken in trawls with no closing mechanism they are highly overestimated. Most records seem to come from bathyal and upper abyssal depths, i. e. approximately 200 – 3000 m. Feeding strategy. A scavenger frequently taken in traps off the east coast of Australia. According to Thurston (1990) K. megalops attacks and feeds voraciously on dead and moribund fish in net catches.	en	Lowry, J. K., Kilgallen, N. M.

Unlike Kyska, Euonyx and Stephonyx both have reduced vestigial coxae on gnathopod 1. Based on the well developed coxa of gnathopod 1 with a concave anterior margin and a compressed carpus Kyska is similar to Abyssorchomene and Koroga. Kyska differs from both genera in the chelate first gnathopod, from Koroga in less well developed eyes and a deeply cleft telson (notched in Koroga) and from Abyssorchomene in the straight mandibular incisors (curved in Abyssorchomene) in the small setose molar and in the tapering margins of the gnathopod 1 propodus.	en	Lowry, J.

03AE8B60AC29FFF76CC1FF2AFA28C6DD.taxon	discussion	Remarks. Six uristid genera (Eclecticus, Galathella, Ichnopus, Nagada, Paralibrotus and Parschisturella, have simple first gnathopods. Parschisturella does not appear to be particularly similar to any of these genera. All have four to five generic level differences from Parschisturella. In Parschisturella gnathopod 1 varies from simple to weakly subchelate to parachelate and the telson varies from moderatly to deeply cleft. All species have a spine on the posterior margin of the gnathopod 1 dactylus. Parschisturella appears to be most smilar to the Australian endemic genus Des. The main differences between Parschisturella and Des are the accessory flagellum cap (absent or partially developed in Parschisturella, large and fully-developed in Des) and the labium (upper lip apically produced in Parschisturella and not produced in Des). Until now Parschisturella has been considered an Antarctic endemic, but it is well represented in the temperate Australian fauna by at least three species.	en	Lowry, J. K., Kilgallen, N. M.

03AE8B60AC38FF996CC1FF2AFC22C734.taxon	discussion	Remarks. Our material agrees very well with the description of Diffenthal & Horton (2007). This is the first record of S. arabiensis outside the type locality in the Arabian Sea. This remarkable range extension from the north-western Indian Ocean into the South Pacific Ocean indicates a wide range for the species. There is no other species of Stephonyx known from this vast area except for the S. biscayensis of J. L. Barnard (1961) and Ledoyer (1986) from Kenya and Madagascar, which appears to be an undescribed species (see remarks under S. biscayensis).	en	Lowry, J. K., Kilgallen, N. M.

03AE8B60AC45FF916CC1F9B7FE3FC151.taxon	discussion	Remarks. Stephonyx pirloti is a distinctive species. It differs from other species in the genus by the epistome which is fused and by the long first article on the mandibular palp. The gnathopod 2 carpus, as illustrated by Sheard (1938) was about 3.5 × as long as the propodus. In material we have examined from Kangaroo Island, the type locality, the carpus is about 2.5 × as long as the propodus. In a selection of material we found a range from 2.2 × to 2.8 × the propodus, well outside the length ratio of Sheard. The most frequent length ratio is about 2.5. In all other respects our material corresponds with the material of Sheard 1938.	en	Lowry, J. K., Kilgallen, N. M.

03AE8B60AC49FF8A6CC1FD22FC31C277.taxon	type_taxon	Type species. Uristes gigas Dana, 1852, monotypy. Included species. Uristes contains 2 species: U. gigas Dana, 1849; U. subchelatus (Schellenberg, 1931). Incertae sedis. Uristes abyssi (Norman, 1900) (family unknown); U. albinus (K. H. Barnard, 1932) (family unknown); U. dawsoni Hurley, 1963 (family unknown); U. entalladurus J. L. Barnard, 1963 (Lysianassidae, Tryphosinae); U. georgianus (Schellenberg, 1931) (family unknown); U. natalensis K. H. Barnard, 1916 (family unknown); U. paramoi (Schellenberg, 1931). Removals. Uristes perspinis J. L. Barnard, 1967 to the tryphosine genus Cedrosella Barnard & Karaman, 1987 based on gnathopod 1 with a tapering first coxa and a short carpus, a non-constricted inner ramus on uropod 2 and a moderately cleft telson. Uristes abyssalis (Stephensen, 1925) is tentatively removed to the tryphosine genus Gronella Barnard & Karaman, 1991, based on mandible molar triturating, gnathopod 1 coxa is slightly tapering, carpus short, propodus margins subparallel and the telson moderately cleft. The condition of the male antenna 2 peduncle (with or without brush setae) and the condition of the inner ramus of uropod 2 (constricted or not) needs to be verified to confirm the generic placement. Uristes barbatipes (Stebbing, 1888) is removed the tryphosine genus Tasmanosa Lowry & Kilgallen, 2014 based on the well-developed antenna 1 accessory flagellum and the triturating molar, maxilla 2 inner plate slightly shorter than outer, the distinctive carpus and propodus of gnathopod 1. Uristes serratus Schellenberg, 1931 and U. yamana Chiesa & Alonso de Pina, 2007 appear to be congeneric, and belong to a yet to be described genus in the Uristidae based on the absence of a callynophore in the female and apparently in the male, the compressed carpus of gnathopod 1 and the cleft telson. Uristes adarei (Walker, 1903); U. antennibrevis J. L. Barnard, 1962; U. californicus Hurley, 1963; U. mediator J. L. Barnard, 1962; U. stebbingi (Walker, 1903); U. sulcus Griffiths, 1974 are removed to the tryphosine genus Tryphosella Bonnier, 1893 based on the triturating molar, maxilla 1 with a 6 / 5 setal-tooth arrangement, the tapering coxa of gnathopod 1. Uristes velia J. L. Barnard, 1961 is removed to the tryphosine genus Cheirimedon Stebbing, 1888 based on the maxilla 1 setal-tooth arrangement; gnathopod 1 carpus short and propodus margins subparallel; pereopod 4 with weak posteroventral lobe; and telson deeply cleft. Diagnostic description. [based on type species] Antenna 1 peduncle article 1 without anterodistal lobe; accessory flagellum not forming cap covering callynophore or flagellum with an elongate article 1 (at least twice as long as article 2) partially covering callynophore. Antenna 2 without brush setae. Mandible molar ridge-like, narrow, setose with narrow distal triturating surface. Maxilla 1 outer plate a well developed 7 / 4 crown. Maxilla 2 inner plate slightly shorter than outer plate. Gnathopod 1 subchelate; coxa 1 large, about as long as coxa 2, subrectangular with straight anterior margin or distally subovate; ischium short (length less than 2 × breadth); carpus short (length 1 to 2 × breadth) to long (length 2 to 4 × breadth); propodus margins subparallel or slightly tapering. Uropod 2 inner ramus not constricted. Telson deeply cleft.	en	Lowry, J. K., Kilgallen, N. M.

03AE8B60AC49FF8A6CC1FD22FC31C277.taxon	discussion	Remarks. As Chisea & Alonso (2007) point out Uristes is in need of revision. The diagnosis provided here is based on the type species. Of the 23 species currently assigned to Uristes, only two remain. Eight of these species are so poorly described that they cannot be placed. Based on the subchelate first gnathopod with a large coxa with a straight anterior margin and a short carpus Uristes appears to be most similar to the Arctic / boreal genera Anonyx and Onisimus. It differs from both in having a ridge-like narrow setose molar with a distal triturating surface and in not having an accessory flagellum cap. Distribution. Southern Ocean and southern Australian waters.	en	Lowry, J. K., Kilgallen, N. M.

Ventiella includes 1 species: V. sulfuris Barnard & Ingram, 1990. Diagnostic description. Antenna 1 peduncle article 1 without anterodistal lobe; accessory flagellum forming cap covering callynophore. Antenna 2 brush setae [unknown]. Mandible molar a reduced column with convex, fully triturating surface. Maxilla 1 outer plate a well developed 7 / 4 crown. Maxilla 2 inner plate subequal to or slightly longer than outer plate. Gnathopod 1 subchelate; coxa 1 reduced, significantly shorter than coxa 2, tapering distally; ischium short (length less than 2 × breadth); carpus long (length 2 to 4 × breadth); propodus margins subparallel. Uropod 2 inner ramus not constricted. Telson notched.	en	Lowry, J. K., Kilgallen, N. M.
