. Carapace wide, ovate, females ca. 1.4 times wider than long; males unknown; lateral margins subcristate; surface with numerous prominent, relatively deep pits. Front narrow, deflexed, broadly triangular in frontal view; straight to weakly sinuous in dorsal view. Orbit transverse; margins entire, unarmed; infraorbital margin mesially terminating in acute angle; supraorbital margin demarcated from antennular fossa by gently curving low ridge; lateral part of orbit distinctly extended laterally to meet the anterolateral margin; inner part of supraorbital margin forms distinct groove which extends to protogastric region. Eyes short, mobile. Antennules folding slightly obliquely. Epistome short, medially sunken. Third maxilliped ischium subquadrate; merus rounded. Thoracic sternites 1, 2 completely fused, broadly angular anteriorly; sternites 2/3 demarcated by shallow groove; sternites 3/4 fused, laterally unarmed; sternites 48 demarcated by narrow grooves, those demarcating sternites 47 incomplete medially; without longitudinal groove. Cheliped merus, carpus unarmed; outer surface of chela, notably at bases of fingers with dense pubescence. P2P5 similar in shape, P3 longest, P5 shortest; merus about twice as long as high, as long as or slightly longer than respective carpi, propodi combined; with plumose setae on flexor, extensor margins; merus of P2P4 usually unarmed or with 1 submedian tooth along flexor margin. P2P5 without short spines on distoflexor angle of propodus opposing dactylus; dactylus very short, claw-like. Male abdomen simple, triangular; telson, all somites free; somite 1 widest; thoracic sternite 8 exposed when abdomen closed. Female abdomen with telson, all somites freely articulating, widest at somite 4. Vulva ovate, maximum width not exceeding half width of sternite 6. (Modified from Ahyong &amp; Ng 2009: 38).
