Carapace width to length ratio 1.26-1.37 (average 1.32); dorsal surface with short setae, granules scattered on branchial regions; epigastric lobes coarsely granular, groove parallel to lateral margins of front shallow; posterior part of cardiac region weakly cristate, coarsely granular; dorsolateral margin distinct as row of large granules reaching to above P5. Anterolateral margin with sharp, high granules immediately after external orbital tooth, forming indistinct lobe; posterolateral margin rounded; posterior margin straight, with distinct submarginal row of large granules. Front beaded submarginally, approximately one-third of width of anterior carapace width, anterolateral angles quadrate from dorsal view; frontomedial portion distinctly bilobed. Supraorbital margin with sharp high granules, middle third weakly convex; infraorbital margin with finely granular ridge placed within orbital shelf; suborbital ridge well developed, with high, sharp granules; 2 rows of granules below suborbital ridge. Interantennular septum with median region ridged; posteromedial tooth triangular, beaded submarginally; posterior margin almost straight. Pterygostomian region finely granular, setose, prominent, broad Y-shaped sulcus. Inner edge of third maxilliped merus thick, with anterior distal angle strongly produced, submarginal oblique row of short setae close to distal edge; ischium roughly circular, moderately deep Y-shaped groove running from outer distal margin to midline, outer distal angle rounded.
