(Laurie, 1906)

The carapace, chelipeds and ambulatory legs have granular surfaces, the granules cover all or part of the carapace and are always conspicuous near the antero-lateral margins. The chelipeds have short fingers; the dactylus is shorter than the width of the palm and articulates on a lower level, in such a manner that the superior margin is at a lower level than that of the superior margin of the palm. The regions of the carapace are poorly defined by large shallow furrows. The antero-lateral margins of the carapace are formed of four lobes of which the three posterior are projecting, the last is obtusely subtriangular. The chelipeds are identical to those of obesus. The carapace is yellowish with a large brown spot on the gastric region. The first pleopod of the male is figured by Guinot (1969, fig. 15). (Serène, 1984)
