A spider crab with characteristic swellings on each side of the carapace, bearing groups of bristles or small spines (hook-setae). The carapace is relatively smooth, narrowed, and grows up to 12 mm long and 8 mm wide. The frontal region produces a small, short, prolongation of the head (rostrum) with a U-shaped incision. Colouration is pale to a reddish-yellow, with lighter chelipeds and pereiopods. The abdomen is separated into 2-5 sections (somites). The pincered legs (chelipeds) are spiny and the walking legs (pereiopods) are covered with long bristles. Chelipeds are spiny, equal and larger in male crabs. The eyestalks are especially long and are always visible.
