Pseudorostral spines straight, thick, short, diverging, V-shaped. Supraorbital eave fused to carapace; pre-orbital angle blunt; postorbital lobe cup-like, fused with hepatic spine, base swollen. Carapace with regions defined; gastric region swollen; epibranchial region slight swell; posterior region with small granule medially ( Fig. 14C); 3 granules along lateral margin of carapace on margin of branchial region ( Fig. 17G). Antennal flagellum slightly longer than pseudorostral spines. Basal antennal article longer than broad, distal angle rounded. Buccal frame covered by third maxilliped. Pterygostomial region with 3 granules on outer margin ( Fig. 16C). Chelipeds slender, covered with setae except on fingers. Ambulatory legs slender, covered with layer of setae except on dactylus; P2 longest. Male tho- racic sternum depressed anteriorly; sternites 3 and 4 with concave surface, margin constricted with curved margin ( Fig. 16C). Male pleon broad triangular ( Fig. 16C). G1 straight, with distal tip sharp ( Fig. 19E–H).   Etymology.The species is named after the country from which the specimen was collected from. The name is used as a noun in apposition.   Remarks.  Crocydocinus vanuatu  n. sp.was identified as  R. aff. brevirostrisby Richer de Forges & Ng (2013)but they noted it differed from the Bay of Bengal specimen as illustrated by Griffin & Tranter (1986: fig. 57c) in several aspects. Comparison of the present material with the typespecimen of  C. brevirostris( Doflein, 1904)  comb. nov.( Figs. 13B, 15B, 17B), revealed more differences, justifying treating them as two separate species.  Crocydocinus vanuatu  n. sp.lacks all the distinct large granules ( Fig. 14C) seen in  C. brevirostris  comb. nov.( Fig. 13B); has only weak lateral branchial spines ( Fig. 14C) (versus distinct lateral branchial spines in  C. brevirostris  comb. nov.; Fig. 13B); and the basal antennal article has a straight outer margin ( Fig. 16C) (versus basal antennal article with slightly convex outer margin in  C. brevirostris  comb. nov.; Fig. 15B).  Crocydocinus vanuatu  n. sp.is only known from its typelocality in Vanuatu. 2268190909 2006-10-13 ZRC, SANTO Vanuatu Expedition 583 Big Bay Espiritu Santo Island 32 33 ZRC 2011.1047, SANTO 2006 1 holotype
