Leach, 1817
Carapace subglobular. Dorsal surface with hepatic region forming a rhomboidal facet behind the orbit. Lateral and posterior margins marked with a continuous beaded line. Front broad. Buccal cavern transversely broad, owing to the enormous width of afferent branchial channels and of the exopodites. Third maxillipeds: exopodite extremely broad, foliaceous, with the outer and anterior borders forming a continuous semicircular curve. Chelipeds not so long, robust. (Guinot 1998)
