(A. Milne Edwards, 1869)
Carapace smooth to naked eye, microscopically granular upon magnification; epibranchial ridges distinct, mesogastrics obscure, cervical grooves conspicuous; front typically bilobed, median notch usually distinct, rarely obscured; 4 very sharp and forwardly directed antero-lateral teeth, decreasing in size fore to aft, fourth sometimes rudimentary. Chelipeds with long hairs on upper and outer faces; merus with 3 teeth and 2 tubercles on anterior border, lower border smooth; carpus with internal spine, otherwise smooth; palm with 2 longitudinal carinae on upper surface. Fifth pair of legs curved back dorsally over the carapace; dactyl slightly shorter than propodus (0.93 times). (Türkay 1995)
Fifth pair of legs turned back dorsally over carapace; front extended and smoothly rounded except for a small median notch, composed of rounded lobes or sinuous (effectively bilobed); carapace not circular in outline and not markedly convex; 4 antero-lateral teeth. (Davie 1999)
