Description
The upper surface of merus of walking legs is sharp, that of carpus and propodus are bicarinate with a longitudinal cavity, the cavity on carpus is larger than that on propodus.

The front which is separated from the inner end of an undivided supraorbital border by narrow cleft is deflexed ventrally, and has a straight border with a median emargination. The antero-lateral border of carpace is upturned and divided into four lobes including the outer orbital lobe. First two lobes have more or less convex borders whereas the last two have a pointed anterior edges. The surface of carapace is distinctly divided into regions by deep grooves, the posterior one-third of carapace along is undivided, 2M is not divided longitudinally. The surface of carapace is more or less completely covered with tubercles of uniform size. The pterygostomial subhapatic and sub-branchial regions are covered with tubercles. A thick fringe of plumose hair is very evident above the base of thoracic appendages. The chelipeds are very unequal in size. The outer surface of arm, upper end and outer surfaces of wrist and almost the entire surface of palm are covered with tubercles similar to those found on carapace. The fingers are short and blunt tipped; the length of dactylus is less than the length of upper border of palm. In the larger chela, dactylus has two teeth and fixed finger has a single subterminal tooth. Of the seven abdominal segments in the male, third, fourth and fifth are completely fused.
