The comparison with specimens of P. miyakei deposited in MNHN showed certain differences. The two species differ in the armament of the second and third pereopods and the mesial faces of the dactyls of the chelipeds. The ventral margins of dactyls of the second and third pereopods of P. miyakei each have a row of 20-28 small corneous spines and the mesial face is unarmed; P. antennarius has 19 or less (16-19 in the specimens examined) corneous spines on the ventral margins of the dactyls of the second and third pereopods, and the mesial faces of these dactyls have a row of small corneous spines on each second pereopod and a shorter row of small spines proximally on each third pereopod. Moreover, in addition to rows of setae near each dorsal and ventral margin of the mesial and lateral faces of propodi of the second and third pereopods, a row of long and dense setae is present medially in P. antennarius, while in P. miyakei this median row of setae is absent. The tubercles on the mesial faces of the dactyls of the chelipeds of P. antennarius are more or less arranged longitudinally in three rows: the first row is situated near the dorsal margin with each tubercle accompanied by tuft of setae, the second and third rows are irregular or scattered with one or two short setae; in P.miyakei the tubercles are arranged in oblique rows. Additionally, the telson in P.antennarius is remarkably asymmetrical, while in P. miyakei it is only slightly asymmetrical. The chelipeds and pereopods of P. antennarius also are covered with longer and denser setae than in P. miyakei. Although these two latter characters are variable, they are constant over the size range and sex of the specimens studied.</p> <p>Paguristes lauriei McLaughlin &amp; Hogarth, 1998 (Fig. 1)</p> <p>Paguristes mundus – Laurie 1926: 154.

Ambulatory legs with scattered splotches of orange on white background colour; mottled orange bands as follows: one submedian band on merus and propodus, two, one subproximal and one subdistal, on dactyl.</p> <p>In the material studied, most of the coloration is still visible especially the dark orange circular patch on distal third of each mesial and lateral face of merus.</p> <p>VARIATION</p> <p>Variation appears to be size related. McLaughlin (in press) noted that the holotype of P. lauriei had unarmed mesial face dactyls of the chelipeds. In the small specimens examined in this study (shield length 1.9-4.0 mm) these surfaces are either unarmed or armed with a longitudinal row of low protuberance or tuberculate spines. In large specimens (&gt; 4.5 mm) they have one or two irregular rows of tuberculate spines dorsally.</p> <p>Most of the large specimens have unequal chelipeds, the right much smaller than left, but the armament is the same. In the largest specimen (SL 6.9 mm) the tuberculate spines on the dorsal surface of palm and fixed finger and the spines on the dorsomesial margin of palm are smaller and widely-spaced.</p> <p>The mesial faces of the second and third pereopods of small specimens are slightly convex; each with only a proximal, shallow longitudinal sulcus dorsally rather than a ridge flanked by sulci dorsally and ventrally in large specimens. Additionally, the row of corneous spines on the mesial face of the dactyl in small specimens is on the proximal half of each second pereopod only, while in large specimens it is on the entire length of dactyl of each second and third pereopods.</p> <p>REMARKS</p> <p>The morphological characters and colour of the specimens examined during this study agree well with McLaughlin &amp; Hogarth’s (1998) description of P. lauriei. McLaughlin &amp; Hogarth described this species from a single female specimen lacking half of the pleon. They assumed that the brood pouch was missing as the eggs were shielded by a uniform row of long, dense, plumose setae arising dorsally from a thickened longitudinal tergal ridge that extended from anterior of the acetabulum of the second pleopod to just posterior of the third (McLaughlin &amp; Hogarth 1998: 20). The presence of female and male specimens in this study provides the opportunity to complete the description of this species. As mentioned by McLaughlin &amp; Hogarth (1998) the thickened pleonal tergal ridges each are interrupted by a short membraneous space between the acetabula of the second and the third pleopods. In the females of this study, above the acetabulum of the fourth pleopod, the tergal ridge is also thickened, short, and separated from the third ridge by a moderately wide space and a large, rounded brood pouch situated adjacent to the fourth pleopod. The eggs are attached to the second, third and fourth pleopods, and only those on the fourth pleopod are protected by the brood pouch, whereas the eggs on the second and third pleopods are shielded by the long, dense, plumose setae.</p> </div>	http://treatment.plazi.org/id/2D4458377D70FFBBFF2EDB53FE0EFDEB	Public Domain	No known copyright restrictions apply.

However, the specimens studied have stouter ocular peduncles, which are only about half length of the shield; the diameters of the corneas are 0.3-0.4 the lengths of ocular peduncles. Komai’s observation of the holotype and others materials from Japan indicated slender ocular peduncles (0.7-0.8 length of shield), with corneal diameters ranging from 0.1 to 0.2 of peduncular length. Some specimens from Madagascar had bifid ocular acicles, possibly as result of a broken tip that regenerated a bifid tip with the molt. The setation is less dense, especially in female specimens. As mentioned earlier, Paguristes species show a high degree of intraspecific morphological variability as demonstrated by McLaughlin (2004) for P. puniceus Henderson, 1896. The differences observed in Madagascar specimens seem to be growth related as they are smaller than those studied by Komai (2001).</p> </div>	http://treatment.plazi.org/id/2D4458377D74FFBBFF3CDDCFFCFEFE34	Public Domain	No known copyright restrictions apply.

Although only one specimen of P. petalodactylus n. sp. is available in this study, a combination of characters distinguish this new species from other species of the genus that have unequal chelipeds and unarmed telson, such as P. alcocki McLaughlin &amp; Rahayu, 2005, P. arostratus Rahayu, 2005, P. balanophilus Alcock, 1905, P. brachyrostris Rahayu, 2006, P. calvus Alcock, 1905, Paguristes sp. (new species to be described by McLaughlin in press), P. frontalis H. Milne Edwards, 1936, P. kimberleyensis Morgan &amp; Forest, 1991, P. lewinsohni McLaughlin &amp; Rahayu, 2005, P. purpureantennatus Morgan, 1987, and P. seminudus Stimpson, 1858. This combination of characters includes broad and flattened dactyls on the second and third pereopods, subrectangular dactyls of the chelipeds, which are covered by small corneous-tipped spines on the mesial faces, and symmetrical lobes of the telson.</p> <p>The apparently most closely related species is P. lewinsohni. These two species are quite similar in general appearance of the shield and cephalic appendages. The differences are in the shape of the dactyls of the chelipeds, which are subtriangular, and the small spines on the mesial faces that are arranged in two irregular rows partially concealed by tufts of moderately short setae with one or two low protuberances ventrally in P. lewinsohni. Furthermore, the ventral margins of the dactyls of the second and third pereopods of P.petalodactylus n. sp. have 20-25 corneous spines, while in P. lewinsohni only 14-20 corneous spines are present. The armature of mesial faces of propodi of the second and third pereopods is also different. In P. lewinsohni a scute-like ridge is developed ventrally, whereas in P. petalodactylus n. sp. there are only simple spinules or protuberances. There is a difference also in the shape of the telson, which is appreciably asymmetrical in P. lewinsohni. Additionally, P. petalodactylus n. sp. has simple ocular acicles, whereas in P. lewinsohni the ocular acicles have two or three spines on distal margin.</p> <p>This new species also is superficially similar to Paguristes sp. (new species to be described by McLaughlin in press) in having a subrectangular right cheliped. However, both chelipeds of P. petalodactylus n. sp. are subrectangular while in Paguristes sp. only the right cheliped is rectangular, furthermore the mesial face of dactyl of the cheliped is covered with small tubercles in the new species, while in Paguristes sp. it is armed with one row of spines. The setation is denser in Paguristes sp. obscuring some armament of the cheliped and pereopods while in the new species the setation is sparse.</p> </div>	http://treatment.plazi.org/id/2D4458377D74FFB4FC95DE89FBACF920	Public Domain	No known copyright restrictions apply.

Meri each with dorsal row of low protuberance, few spines and long, dense plumose setae proximally; ventral margins each with row of dense long plumose setae, mesioventral margin with several small corneous-tipped spines (second) or unarmed (third). Ischia each with one or two spinules on ventromesial margin distally and dense plumose setae. Fourth pereopods each with preungual process at base of claw, no distal spine on dorsal margin of carpus.</p> <p>Male with paired first and second pleopods. Male first pleopods (Fig. 5D, E) each with tuft of setae on superior mesial angle of basal lobe; distal margin of inferior lamella unarmed; external lobe overreaching inferior lamella, internal lobe short, with marginal setae. Second pleopods (Fig. 5F, G) each with basal segment glabrous; endopod with row of moderately long setae on mesial margin, distal angle with tuft of stiff setae; appendix masculina with long setae on distal margin and inferior surface. Female with single gonopore on coxa of third left pereopod, first pleopod 2-segmented. Brood pouch small, obtusely triangular with marginal long plumose setae. Eggs small, attached to second and third pleopods.</p> <p>Telson (Fig. 5H) with moderately deep lateral incisions separating anterior and posterior portions; posterior lobes asymmetrical, separated by small, V-shaped median cleft, terminal margins each armed with three to six spines.</p> <p>VARIATION</p> <p>In small female specimens (SL ≤ 2.6 mm) the setae on chelipeds and pereopods are less dense; and the ventral margins of the dactyls of the second and third pereopods each have four to 10 corneous spines. In</p> <p>male specimens the terminal margins of posterior lobes of telson have five or six spines.</p> <p>REMARKS</p> <p>Stratiotes abbreviatus was described by Dechancé (1963) as Paguristes abbreviatus. Rahayu (2005) revised Paguristes s.l. and transferred to Stratiotes those species with 12 pairs of gills. Examination of Dechancé’s taxon has shown that it has 12 pairs of biserial gills; therefore it is also transferred to Stratiotes. The redescription herein included is based on the holotype, paratypes and the specimens collected by Thomassin in Tuléar, Madagascar.</p> <p>Differences were observed in setation between the types and the specimens reported herein. In the holotype and paratypes, the setation of the chelipeds and pereopods is much reduced; the specimens are almost glabrous. It is probable that the setae were removed during a previous study in order to see the armament clearly. On the specimens from Tuléar the setae were dense and matted by mud. When the mud was removed, the plumose setae and row of stiff setae circumscribing each spine were revealed. The shape of shield and cephalic appendages and the armament of the chelipeds and pereopods showed that they all belong to the same species.</p> <p>The female brood pouch, although small, is present in the females examined, while Dechancé (1963: 298) mentioned that types were “sans repli membraneux sur l’abdomen”. The holotype and paratypes have broken or damaged pleons, and it is probable that the brood pouches are missing.</p></div> 	http://treatment.plazi.org/id/2D4458377D7DFFAFFE9BDDCFFDC0FB63	Public Domain	No known copyright restrictions apply.
