Dorsal surface of carapace uniformly covered with closely-set granules of irregular size; there are a few blunt tubercles on the gastric, branchial and cardiac regions; spines are only present in the lateral margins. In fully developed males chelipeds massive, carpus dorsally smooth with few blunt, short tubercles dorsolaterally in some specimens, strong teeth on inner margins and the palm of the cheliped is smooth. Propodi of pereopods are without spines, but have the presence of long and short dark setae.
