Carapace transversely oval, depressed, smooth, almost flat behind the deflexed finely granular fronto-orbital region; no distinct regional boundaries. The anterolateral border is fairly sharp and is obscurely divided into four shallow lobes, the first two of which are rounded and almost confluent. Front between a third and a fourth the greatest breadth of the carapace, bluntly four-partite. Orbits with the margins entire, eyes small. The buccal cavern is distinctly narrower anteriorly than posteriorly. Cheliped unequal, very massive, quite smooth to the naked eye; two strongish tubercles at the inner angle of the wrist; fingers arched, pointed, in the adult male they meet only at tip. Legs smooth, dactyli furred, a few fine scattered silky bristles on the propodite.
