Rafinesque, 1815
Carapace very broad, of typical portunid-shape. Antero-lateral margins with four to nine teeth. Antennae with the basal article usually broad, its antero-external angle sometimes lobulate; flagellum sometimes included in the orbit. Ambulatory legs shorter than chelipeds; P5 typically paddle-shaped. (Guinot 1998)
Carapace subhexagonal, rarely subcircular, usually distinctly broader than long; antero-lateral margin divided into more than five teeth (5-9). Basal antennal segment elongated, lying obliquely, with antero-lateral lobe not filling orbital hiatus; antennal peduncle and flagellum standing in orbit. Chelipeds longer than ambulatory legs, bearing a set of spines on merus, carpus and palm; last pair of legs with paddle-shaped propodi and dactyli. Male first gonopod without subterminal spines. (From Apel & Spiridonov, 1998).
