(Dana, 1852)
The dorsal surface of the carapace is smooth or granular, less convex, and with the regions well or slightly defined. The chelipeds have the anterior margin of the merus smooth or granular and with or without a protuberance or proximal spine; the palms are not very elongated. The cheliped merus has a protuberance or a proximal spine on the anterior margin. The carapace has the dorsal surface smooth, without the regions distinctly indicated. The antero-lateral margins of the carapace have, behind the orbital angle, four teeth of which some are nearly obsolete but never fused with one another into a convex, elongated lobe. The antero-lateral margins of the carapace have teeth 1 and 4 very small or even obsolete and teeth 2 and 3 well developed. The ambulatory legs have sparse, plumose setae. The frontal submedian lobes are without defined furrows for the length of their margin. The neighbouring antero-lateral margins of the carapace are without well defined areolas. (Serène, 1984)
