Diagnosis: Rostrum curved upward on proximal region and curved downward on distal region, with 3 big proximal teeth, ventral margin with some simple setae. Cervical carina absent; hepatic sulcus present. Abdominal somites 3–6 with dorsal spines, the first one the largest and the last one extremely reduced. Thelycum with a semioval plate on sternite XII and with a spine on sternite XIII. Male sternum with a semioval plate on sternite XII. Petasma with ventral costa smaller than lateral lobe, curved outward, with extremity enlarged, not forming a hook; median lobe smaller than lateral lobe. Appendix interna semioval with cuspidate setae on distal extremity. Appendix masculina filiform, smaller and thinner than appendix interna, with marginal simple setae.

Description: Rostrum curved upward on proximal region and curved downward on distal region, with 3 big proximal teeth; some simple setae on ventral region of rostrum and in front of rostrum spines ( Fig. 8 View FIGURE 8 a). Adrostral carina well defined; cervical carina absent; branchiocardiac, branchiostegal, gastro-orbital and submarginal carina present; hepatic sulcus present; antennal and branchiostegal spines present ( Fig. 8 View FIGURE 8 a).

Abdominal somites 1–3 with a depression that extends from the dorsum to half of pleurae; pleurae with marginal setae; tergum with medial carina on somites 3–6; abdominal somites 3–6 with dorsal spines, the first is the largest and the last extremely reduced ( Fig. 8 View FIGURE 8 a).

Antennal scaphocerite approximately 1, 6 X of antennular peduncle ( Fig. 3 View FIGURE 3 a–c).

Right and left mandibles with incisor and molar processes distinct; palp present ( Fig. 8 View FIGURE 8 d, 8e).

Maxillae, maxillipeds as for the family ( Figs. 8 View FIGURE 8 f–g, 9a–c).

First pereopod dactyl approximately 1.5 X of palm; palm with setae tufts on proximo-ventral region; carpus approximately 1.5 X of dactyl; merus approximately 1.5 X of carpus, with one disto-lateral cuspidate setae ( Fig. 9 View FIGURE 9 d).

Second pereopod dactyl approximately 1.3 X of palm; carpus approximately 2 X of dactyl; merus approximately 1.2 X of carpus, with a disto-lateral cuspidate setae ( Fig. 9 View FIGURE 9 e).

Third pereopod dactyl approximately 1.3 X of palm; carpus approximately 2.6 X of dactyl and of the same size of merus; male coxa with a small inner spine ( Fig. 9 View FIGURE 9 f).

Fourth pereopod dactyl approximately 0.5 X of propodus; propodus approximately 0.6 X of carpus; carpus approximately 0.8 X of merus; male coxa with a small inner spine ( Fig. 9 View FIGURE 9 g).

Females with sternites IX–XI with ventral spines; sternite XII with an oval plate ending in a spine; sternite XIII with a ventral spine ( Fig. 10 View FIGURE 10 a). Males with sternite XI with a ventral carina; sternite XII with an oval plate ending in a spine ( Fig. 10 View FIGURE 10 b).

Petasma with ventral costa smaller than lateral lobe, curved outward, with extremity enlarged, not forming a hook; median lobe smaller than lateral lobe ( Fig. 10 View FIGURE 10 c–d). Appendix masculina semioval with cuspidate setae on distal extremity ( Fig. 10 View FIGURE 10 e). Appendix interna filiform, smaller and thinner than appendix masculina, with marginal simple setae ( Fig. 10 View FIGURE 10 f).

Variation: One male (MNRJ 14532) has one disto-lateral cuspidate setae on merus of third pereopod besides those on first and second pereopods.
