(H. Milne Edwards, 1834)
The carapace is narrower (B/L <1.5), the surface rugose or finely granular. 2M is always divided into two longitudinally. The ambulatory legs (except for granulatus) only have scattered setae. The ambulatory legs are feebly and irregularly setosed. The carapace is more feebly granular. The abdomen of the male has the telson and segment 6 both as broad as long. The front has strong and projecting external angles. The front has very convex submedian lobes separated from the external angles by a strong concavity. The first pleopod of the male has, in the preapical region, about 30 long, strong spines and plumose setae, all directed backwards. (Serène, 1984)
