This species is distinguished by the breadth of the front being 39-40 percent of the distance between the external orbital angles, its free edge being not distinctly crenulate. The tooth at the inner angle of the wrist of the chelipeds is nearly straight, not talon-like; the length of the upper border of the palm is nearly two-third the length of the dactylus. The first pair of legs is about as long as the last pair. The greatest breadth of the meropodites of the last pair is half its length. The distal part of the posterior margin of the last legs dentate.
The propodites in all the legs have a terminal spine on the posterior border
The anterior male abdominal appendages are very thick and have two lobes at the tip. The inner lobe bears a thick brush of dark brown hairs, while the outer bears lighter straw-colored hairs and a patch of spinules.
