Carapace slightly broader than long, sub-circular, convex with thin edges, dorsal surface strongly convex medially. Front projecting a little beyond the supra-orbital angles, arched, entire though dorsally concave in the middle line, its breadth is between a half and a third the greatest breadth of the carapace. Anterolateral borders curved, divided into five lobes or rather broad flat puckers. Orbits small, their major diameter is about a fourth the width of the inter-orbital space. Antennal flagella short. Chelipeds a little longer than the carapace. Inner angle of wrist dentiform. Upper surface of hand with two carinae, each ending in a blunt tooth, there is also a little tubercle in front of the apex of the wrist joint and an obscure ridge along the outer surface. Fingers stout, a little shorter than the palm, the dactylus sharply carinate dorsally. Legs stout, slightly shorter than the chelipeds, the merus of the last pair is about twice as long as broad and its posterior border, like that of the propodite is smooth.

Crabs are symbiotically associated with various species of sea cucumbers.
