36779A25657EFFF1FF2FFF5BFF50A1E9.taxon	etymology	Etymology. This genus is named after the name of the island “ Kume ”, where the expedition “ KUMEJIMA 2009 ” took place. Gender is masculine.	en	Naruse, Tohru, Ng, Peter K. L.

36779A25657EFFF1FF2FFF5BFF50A1E9.taxon	discussion	Remarks. Kume n. gen. superficially most closely resembles Pele in its very broad carapace (Figs. 1, 2 a; Ng, 2011: figs. 3 A, 4 A, 5, 7 A). Kume n. gen. can be separated from Pele by the presence of an oblique granulated crest on the metabranchial region of the carapace (vs. absent in Pele; Ng 2011: figs. 5 A, B, 7 A); proportionately shorter ischium and slightly auriculiform distolateral angle of the merus of the third maxilliped (Fig. 2 c) (vs. proportionately longer ischium and non-auriculiform angle; Ng 2011: fig. 7 D); unarmed anterior margin of the cheliped merus (Fig. 2 d) (vs. armed with subdistal tooth in Pele; Ng 2011: figs. 2 C, 4 A, 8 A), lanceolate dactylus of P 5 (Fig. 2 f) (vs. almost straight, slightly upcurved in Pele; Ng 2011: figs. 3 A, 4 A, 8 B); the male has symmetrical chelae and the occlusal margins of the fingers have normal teeth (Fig. 2 d, e) (vs. with unequal chelae and spine-like teeth along occlusal margin of pollex of minor chela in Pele; Ng 2011: fig. 6 C); rod-like press-button male abdominal locking mechanism (Fig. 3 a, b) (vs. peg-like in Pele; Ng 2011: fig. 7 E, G); the complete absence of a longitudinal median line on the sternoabdominal cavity (Fig. 3 b) (vs. shallow line present in Pele; Ng 2011: fig. 7 E); the relatively smaller and elliptically shaped vulva (vs. large, rounded in Pele; Ng 2011: fig. 9); short and broad telson with a relatively broader anterior part of the sternoabdominal cavity (Fig. 3 c) (vs. elongated, linguiform telson and relatively narrower sternoabdominal cavity; Ng 2011: fig. 8 C); almost straight, simple G 1 (Fig. 3 d) (vs. G 1 with a stout base and long, straight and slender distal part, sharply bent medially in Pele; Ng 2011: figs. 6 A, 8 D, E); and bifurcated distal end of G 2 (Fig. 3 e) (vs. unilobed in Pele; Ng 2011: fig. 8 F). Kume n. gen. is also similar to Libystes A. Milne-Edwards, 1867, sensu lato, in its unarmed anterior margin of the cheliped merus (Fig. 2 d) and the slender dactylus of P 5 (Fig. 2 f). The differences between Kume n. gen. and Libystes are: broad and elliptical shape of the carapace (Figs. 1, 2 a) (vs. subquadrate to subovate in Libystes); slightly produced distolateral angle of the third maxilliped (Fig. 2 c) (vs. prominently auriculiform in Libystes); the absence of the longitudinal median line on the sternal cavity (Fig. 3 b) (vs. longitudinally line present, but posterior end fused in Libystes); and the G 1 is gently curved, subcylindrical with a tapering distal part (Fig. 3 d) (vs. very slender and sinuous or short and subtruncate in Libystes) (see Ng 2011 for details of Libystes). Ng (2011) has discussed the systematic problems with Libystes and the allied genus Catoptrus A. Milne- Edwards, 1870, at length (see also Fujita & Naruse 2011), noting that Libystes will need to be separated into at least two groups in an ongoing revision of the genus by the present authors. As such, this matter will not be elaborated on here.	en	Naruse, Tohru, Ng, Peter K. L.

36779A25657DFFF5FF2FFF11FF67A18D.taxon	description	Description. Carapace broadly transverse, carapace width 1.94 – 2.12 times length, dorsal surface almost smooth except for granulated epi- and mesobranchial regions and prominent oblique granulated crest on metabranchial region. Frontal margin almost straight, slightly produced, deflexed medially, medially notched in dorsal view. Supra- to infraorbital magins continuous, rimmed, supraorbital margin without fissure; infraorbital margin concave on mesial half. Orbit rounded; eyes mobile, relatively short, with thick eyestalk, upper surface rather flattened, almost completely filling orbit; cornea well developed. External orbital angle low, indistinct, anterolateral margin with 5 small teeth, weakly cristate between first to fifth teeth, teeth slightly larger than granules on branchial regions, first to fourth teeth placed equidistantly, maximum width of carapace between fifth teeth. Subhepatic and pterygostomial regions granulated. Epistome relatively narrow longitudinally; posterior margin with distinct median notch. Endostomial ridges distinct. Third maxilliped rectangular, ischium slightly longer than merus without trace of median sulcus; merus with distolateral angle produced; distal end of exopod not reaching distolateral angle of merus, with long flagellum. Male thoracic sternum relatively broad; sternites 1 – 3 completely fused; sternites 3 and 4 delimited by groove, deep medially, shallow laterally; sternoabdominal cavity relatively wide; sutures between thoracic sternites 4 – 8 medially interrupted, ending just at inner part of lateral slope of cavity; distinct press button present near inner end of suture 4 / 5 on sternite 5; no longitudinal line discernible; slight depression visible on each side below level of inner ends of suture 7 / 8. Female thoracic sternum wide, condition of sternites same as male; vulva on middle part of sternite 6; transversely elliptical. Chelipeds subequal in male and female, relatively long, robust; chela as long as carapace width; merus slightly longer than palm, triangular in cross-section, anterior margin lined with granules, without distinct tooth or spine; carpus short, smooth, inner angle rounded. Chela relatively long, palm shorter than fingers; fingers straight in outer view, weakly curved inwards in upper view, distal ends strongly hooked; occlusal margins lined with numerous sharp teeth. P 2 – P 4 similar in shape, P 2 longest. Male P 2 granulated on anterior and posterior margins of merus, outer, inner margins of propodus, outer margin of dactylus; granulation relatively weaker in P 3; P 4 similar but no granulation on posterior margin of merus and inner margin of propodus. Female legs similar to that of male, but P 2 propodus granulated only on inner margin, P 3 and P 4 meri and dactyli granulated only on anterior margins and outer margins, respectively. P 5 in both sexes shortest, propodus slightly longer and wider than carpus, laterally flattened; dactylus slightly longer than propodus, lanceolate, laterally flattened, outer margin nearly straight, outer margin and distal quarter of inner margin lined with fine spines. Male abdomen relatively wide; somite 1 longitudinally narrow; somite 2 laterally separated but functionally fused to somite 3 medially, without indication of a suture; somites 3 – 5 completely fused; telson triangular, tip rounded, slightly broader than long; somite 3 to telson forming almost right-angled triangle. G 1 simple, gently curving outwards, distal half almost straight, cylindrical in shape, tapering gently to subtruncate tip. G 2 slender, about half G 1 length, tip distinctly bifurcated. Colour. In life, the carapace is pinkish to yellowish white, while the ambulatory legs are white with pink patterns. The cheliped is also pinkish white, but the fingers are striped with white and maroon (Fig. 1). The striped pattern is somewhat variable, being prominent in the two female specimens (Fig. 1 b) but less obvious in the holotype male (Fig. 1 a).	en	Naruse, Tohru, Ng, Peter K. L.
