de Haan, 1833
The front is bilobed, almost straight and bordered with denticles, acute granules or even spines. The carapace, the carpus and the palm of the chelipeds are furnished with acute granules (sometimes spinose). On the back of the carapace, region 1M is indistinct and smooth. The almost straight margin of each frontal lobe is covered with numerous small, acute granules that are also found on the exorbital angle. The surface of the carapace is furnished with similar but blunt granules near the antero-lateral margins and particularly at the anterior margin of 2M where there is a row of transverse granules. The chelipeds have some coarse granules mixed with small ones, particularly on the superior and external surfaces of the larger cheliped palm. The carapace is comparatively narrower and furnished with more coarse and more numerous granules. The fingers of the larger cheliped are black but white at the distal extremities; in the male the black colouration on the fixed finger extends onto the palm. (Serène, 1984)
