Carapace distinctly transverse, high; dorsal surface strongly convex longitudinally and transversely; smooth; grooves weak to indistinct; regions poorly defined; epigastric cristae very weak, indistinct, confluent with postorbital cristae; postorbital cristae indistinct, rounded; antennular fossae slit­like; external orbital angle acutely triangular, separated from epibranchial tooth by distinct, rounded cleft; epibranchial tooth distinct, very low, rounded; anterolateral margin distinctly convex, entire, very weakly cristate; median tooth of posterior margin of epistome low, lateral and outer parts forming continuous sinuous margin, with lateral part convex and outer part gently concave. Ischium of third maxilliped broadly rectangular; exopod reaching beyond upper edge of ischium, with well developed flagellum subequal to or exceeding width of merus. Chelipeds distinctly unequal. Ambulatory legs moderately long, with long, slender dactyli. Suture between thoracic sternites 3 and 4 demarcated by strong ridge; abdominal cavity reaching imaginary line joining median points of coxae of chelipeds. Male abdomen narrowly triangular. G1 terminal segment about 0.3 times length of subterminal segment, subcylindrical, straight, tip truncate with inner distal angle produced as sharp, narrow projection, proximal part with narrow, hump­like, dorsal flap; subterminal segment relatively slender. G2 with distal segment longer than half of basal segment.

Carapace distinctly transverse, 1.43–1.52 times broader than long, high; dorsal surface strongly convex longitudinally and transversely, smooth; epigastric cristae very weak, indistinct; postorbital cristae indistinct, rounded; external orbital angle acutely triangular, separated from epibranchial tooth by distinct, broad rounded cleft; epibranchial tooth low but distinct, rounded; anterolateral and posterolateral margins very strongly convex and strongly converging, respectively. Third maxilliped exopod reaching beyond distal margin of ischium, flagellum well developed, subequal to or exceeding width of merus. Ambulatory dactyli long, slender. Suture between thoracic sternites 3 and 4 demarcated by strong incomplete ridge, not fused with tip of margin of abdominal cavity. Male abdomen narrowly triangular; segment 6 with lateral margins very gently convex. G1 terminal segment about 0.3 times length of subterminal segment; subcylindrical, straight, tip truncate with inner distal angle produced as sharp, narrow projection, with narrow, hump­like, dorsal flap in proximal part; subterminal segment relatively slender. G2 with distal segment longer than half­length of basal segment.
