Upper and lower inner orbital angles not in contact. Ambulatory legs are very shaggy. Carapace and chelipeds are generally smooth, wrist bears two teeth at inner angle. External orbital angle normally dentiform.

Length of carapace nearly three-quarters the breath. The regions are all convex and well defined and the gastric and branchio-hepatic regions are subdivided into convex lobules, the surface of which is somewhat dented transversely. The antero-lateral border is cut into four procurved teeth, the last two of which are claw like.The front projects strongly, and is divided into two dorsally-convex lobes, of which the free edge may either be cut obliquely inwards, or be so excised as to give the front a four-pronged look. Chelipeds in the male not much more than half again as long as the carapace. The upper and anterior borders of arm hairy; upper surface of wrist nodular, with two teeth at the inner angle; upper outer surface of hand with rather irregular longitudinal series of little nodules and granules; dactylus fluted. Legs very shaggy, the hairs almost concealing some lines of sharp granules or spinules on the propodite and dactylus.

The bright and distinctive color pattern of this species is characteristic of many known poisonous species, and is an indirect confirmation of their toxicity.
