Diagnosis

Carapace with pseudorostral and supraocular spines long, subequal; supraocular spine with distinct submedian accessory spine; gastric region with small but distinct sharp granules in addition to 3 major spines; branchial regions convex; subhepatic region swollen, with 2 large dorsal and 2 small ventral spines; protogastric region with 2 major spines; basal antennal spine triangular, relatively broad; P2–P4 long, slender, subcylindrical, merus with 6 or 7 spines on dorsal margin, outer surface with 3–10 small spines, ventral margin with 15–21 spines; P5 with 1 or 2 spines on dorsal margin, 4 small spines on outer surface, 4 or 5 spines on ventral margin, subchelate structure stout, propodus with 3 large basal spines, rest of margin with distinct, closely arranged spines of similar size. G1 stout, short, groove on ventral surface median, dorso-median surface concave, distal part rounded, opening relatively smaller, flap-like, not auriculiform, directed towards median part of sternum.
