Diagnosis: Rostrum curved upward with 3 proximal large teeth. Cervical carina reduced; hepatic spine absent. Abdominal somites 3–6 with a dorsal carina with small dorsal spines. Thelycum with a mesial shieldlike protuberance on sternite XII and sternite XIII with a rounded protuberance. Male sternum with a large spine on sternite XII. Petasma with distal extremity somewhat rounded; ventral costa smaller than lateral lobe, sligthly curved inward, not forming a hook. Appendix interna sub-triangular. Appendix masculina triangular, setose on inner margin, smaller and thinner than appendix interna. Description: Rostrum curved upward with 3 proximal large teeth; some simple setae on ventral region of rostrum and in front of rostrum spines ( Fig. 11 a). Adrostral carina well defined; branchiocardiac carina extends for almost total length of carapace; cervical carina reduced; Branchiostegal and submarginal carina present; antennal and branchiostegal spines present ( Fig. 11 a). Abdominal somites 1–3 with a depression that extends from the dorsum to the middle of pleurae; pleurae with marginal setae; tergum with a dorsal carina on abdominal somites 3–6; abdominal somites 3–6 ending in small spines ( Fig. 11 a).

Second pereopod dactyl approximately 1.4 X of palm; carpus approximately 1.8 X of dactyl, with nine photophores; merus approximately 1.5 X of carpus, with a disto-lateral cuspidate setae ( Fig. 12 e). Third pereopod dactyl approximately 1.4 X of palm; carpus approximately 1.5 X of dactyl and of the same length of merus ( Fig. 12 f). Fourth pereopod dactyl approximately 1.5 X of propodus; propodus approximately 0.6 X of carpus; carpus approximately of the same length of merus ( Fig. 12 g). Fifth pereopod dactyl approximately 0.6 X of propodus; propodus approximately 0.4 X of carpus; merus approximately 1.4 X of carpus; male coxa with an inner spine ( Fig. 12 h). Females with sternites VIII–X with ventral spines; sternite XII with a shield-like plate; sternite XIII with a rounded protuberance (Fig. 13a). Males with sternites IX–XI with ventral spines; sternite XII with a large spine; sternite XIII with a truncate spine (Fig. 13b). Petasma with distal extremity rounded; ventral costa smaller than lateral lobe, sligthly curved inward, not forming a hook (Fig. 13c–d). Appendix masculina sub-triangular (Fig. 13e–f). Appendix interna triangular, setose on inner margin, smaller and thinner than appendix masculina (Fig. 13f). Variations: One male (MNRJ 14581) has 2 distal truncate small spines besides those rostral ones. One female (MNRJ 14594) has a disto-lateral cuspidate setae on merus of third pereopod, this seta is equal to those present on merus of first and second pereopods. Distribution: Western Atlantic Ocean: Delaware to Florida; Gulf of Mexico ; Caribbean Sea to French Guiana ; Brazil (Maranhão and Amapá states) ( Pérez Farfante & Kensley, 1997 ; Silva et al. , 2002 ). Depth: 200–750 m , occasionally to 1100 m ( Pérez Farfante, 1988 ). New records: Brazil—from Bahia to Espirito Santo states, between 522 m and 1144 m .
