Alcock, 1899
Carapace almost as long as broad, rudely semicircular, very inflated, convex fore and aft and vertically deflexed. Dorsal surface with all the regions tumid, except the posterior; cardiac and branchial regions well delimited. Antero-lateral margins entire. Fronto-orbital border more than half the greatest breadth of carapace. Front considerably less than a third the breadth of the carapace, bilobed, vertically deflexed. Orbits small, shallow, excavated in the vertically deflexed anterior margin of the carapace. Eyestalks immovably fixed. Eyes very small but well formed and pigmented. Antennulary fossae completely filled by the basal article, to the exclusion of the flagellum. Basal antennal article small and slender; flagellum arising in the orbital hiatus. Epistome considerably broad fore and aft and, though sunken, well defined from the endostome. Buccal cavern subsquare, completely closed by the third maxillipeds. Merus of third maxillipeds shorter and slightly narrower than the ischium, and oval in shape; palp jointed to the antero-internal angle of the merus. Ambulatory legs long and slender; dactylus slender. (Guinot 1998)
