Carapace slightly oval transversally, smooth, without well defined regions. Front broad, bilobed, without distinct inner orbital lobes. Anterolateral margins of carapace with four prominent teeth, the posterior ones sharp and slender. Basal antennal segment slender, twice as long as broad. Antennal flagellum entering orbit. Third maxilliped merus slightly longer than wide, with the antero-external angle barely produced. Ocular peduncle short and thick, lacking tubercle on anterodistal border in front of cornea. Chelipeds large, unequal, longer than other pereiopods, lacking pronounced carinae; merus long, bearing 2-4 strong, sharp teeth on anterior border; carpus with 2 spinous teeth; outer surfaces of chelae without teeth. Pereiopods 2-4 slender, long. Pereiopod 5 with propodus and dactylus widened, flat, forming swimming paddle. Male abdomen triangular; third to fifth segments fused. First male pleopod rather stout throughout its length, sinuous, with a slightly bilobed distal part.
