Diagnosis. Often hermaphroditic, having both four pairs of oostegites and male penal cone mid-ventrally on pereonite-6. Rostrum weakly incised at base, with slightly rounded, non-serrate shoulders, becoming immediately constricted distally to form, short, acute tip. Left mandible with lacinia mobilis having five denticles (proximal being most minute). Mandibular palp with article-1 having cluster of 20−25 simple setae. Pereopod-1 with propodus having ventral margin bearing two, rarely three, stout spiniform setae.

bears a relatively small, blunt spiniform process (Fig. 12A) and there is a distinct mid-ventral, genital cone on pereonite-6. There are no indications of oostegites. The female cheliped exhibits two morphotypes; one having a narrow carpus with length more than three to four times width (Fig. 12B), and the other being robust and similar to that of male. Both female cheliped forms lack a blunt spine on the dorsoproximal margin of the basis (Fig. 12B−C). and there is no indication of a genital cone on pereonite-6. Adult hermaphrodites have
