Description
Rostrum acute at tip, directed forward (Fig. 5a). Carapace with a dorsal carina with two small spines (Fig. 5a). Cornea approximately 1/3 of ocular peduncle. Ocular peduncle broad, with a big innerlateral spine that surpasses cornea and rostrum (Fig. 5a).
Mandible with 10teeth incisor process; without molar process; with palp (Fig. 5b,c). Pereiopod 1, merus with 1618 cuspidate setae. Pereiopod 2, carpus with a big innerlateral spine; merus with 2326 cuspidate setae; ischium with 12 cuspidate setae; basis with 13 16 cuspidate setae (Fig. 5d). Pereiopod 3 long and filiform, reaching half of P2 palm. Pereiopod 4 and pereiopods 5 reduced, P4 smaller than P5. Abdominal somite 4 with a dorsal spine. Male endopod with marginal articulate plumose setae, with hooked setae on distal lobe (Fig. 6 a,b). Appendix interna with terminal hooked setae (Fig. 6 c,d). Appendix masculina approximately 2/3 length of appendix interna, with marginal cuspidate setae (Fig. 6 c).Telson long, sulcate on almost its entire length, with ten terminal cuspidate setae of different sizes, outer ones bigger than inner ones (Fig. 6 e).
