Size: Max length 1.6 cm CW (male); 1.45 cm CW (female).

Carapace smooth (non granular); anterolateral borders of carapace with a single tooth at their anterior end.

Carapace etc, with a short velvet like tomentum. Carapace longer than broad, convex, smooth, without distinction of regions. Cervical groove broad and shallow. Front cut into 3 teeth, the lateral ones broad and triangular, the middle one so small and deflexed as to be hardly visible in a dorsal view. There is no distinct tooth in the upper border of the orbit, but only an angular bulge, to mark the position of the inner supra-orbital angle. Outer orbital angle and sub-orbital lobe not dentiform. The anterolateral borders of the carapace are smooth and entire. The chelipeds and legs have an uneven surface, but are not really nodular, though both inner and outer angles of the wrist are strongly pronounced. The last 2 pairs of legs are short and slender, but are not really nodular, though both the inner and outer angles of the wrist are strongly pronounced. The last 2 pair of legs are short and slender, the 4th (last) pair being very little longer than the 3rd, both end in stout claw-like dactyli but are not at all cheliform. The abdomen bends in very sharply from the 4th segment making the undersurface of the body very flat.

Crabs always carry a mass of sponge or compound ascidians for camouflage.
