EMENDED DIAGNOSIS BY Devillez et al. (2016). — Fusiform intercalated plate; inflated hepatic, cardiac and branchial regions; deep cervical groove, joined to dorsal margin and to antennal groove; deep, long gastro-orbital groove, originating as a slight median inflexion of the cervical groove, with two divergent, curved branches, delimiting two gastro-orbital lobes; strongly inclined postcervical groove, inflected before joining hepatic groove, not joined to dorsal margin; short and shallow branchiocardiac groove, joined to dorsal margin and not joined to postcervical groove; concave hepatic groove, joined to cervical groove; shallow cardiac groove, straight, inclined forward, rising from postcervical groove, joined to dorsal margin; cephalic region with strongly tuberculate antennal row and distal antennal spine; carapace with tuberculate ornamentation; chelate P1-P3; P1 with strongly tuberculate ornamentation; short P1 propodus with fingers barely longer; P1 dactylus longer than P1 index.
