Description
Size: Max length 6.0 cm CL (male); carapace width: 8 cm

Front thick and obtusely truncate, carapace covered with course tubercles, which become squamiform towards posterior surface, hepatic regions strongly depressed.

Carapace length is nearly five sixths the extreme breadth. Carapace, wing like expansion of the arm, upper surface of wrist and outer surface of palm are covered with coarse tubercles. Posterior part of carapace are squamiform tubercles. The anterolateral border of the carapace is crenulate, and the posterior border is finely beaded and quite unarmed. The pterygostomian regions have only a few scanty hairs. The front is emarginate, and projects well beyond the orbits, forming a laminar rostrum. The wing like expansion of the end of the arm is conspicuously four-lobed; the crest of the palm is 6 or 7 dentate.

In the young specimens, the tubercles of the carapace and chelipeds are sharper and crisper and the antero-lateral borders of the carapace are sharply serrate.
