Organism information awaits expert curation
Class: Malacostraca

Dorsal view of crab

Size (male): Length of carapace: 52 mm; breadth of carapace: 55mm

Color: Reddish brown

This crab is distinguished by the absence of a true front, so that the antennular fossae are visible in a dorsal view as deep clefts in the anterior border of the carapace. The regions of the carapace are distinct, and covered with flat pearly or squamiform tubercles. The antero-lateral borders are cut into four teeth. The chelipeds are massive,and have tubercles on the upper surface of the palm and finger arranged in longitudinal rows.
The tubercles on the surface of carapace are variable, sometimes obscure, or flatfish or very prominent. Hairs also vary, either absent or just fringes of bristles or thickly covered the inter spaces between the tubercles.
