Material examined E0519, 13°19.944’ S, 38°19.654’ W to 13°22.615’ S, 38°21.960’ W, 1730 m, 20/ VI / 2000, 1 male, cl: 20.9 mm, MNRJ 19528.
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).
Distribution
Eastern Pacific, from Oregon; North Atlantic. Depth: Taken in midwater tows between 1250 and 1500 m and in tows made in the water column between the surface and 2870 m (Hendrickx & Estrada­Navarrete 1989).

Rostrum acute, slightly curved upward, reaching half of ocular peduncle (Fig. 7a). Carapace with a dorsal sulcate carina. Eyes with cornea of approximately half of ocular peduncle; ocular peduncle with inner­lateral spine, not reaching cornea distal extremity. Mandible with 9­teeth incisor process; without molar process; with palp (Fig. 7b,c). Pereiopod 1, setose without spines and cuspidate setae. Pereiopod 2, propod with six cuspidate setae; carpus with a big inner spine; merus with 4­5 cuspidate setae; ischium with 2 cuspidate setae (Fig. 7d). Pereiopod 3 long, filiform, reaching palm of P2. Pereiopod 4 and pereiopod 5 reduced, with fingers very setose, P4 smaller than P5. Abdominal somite 4 with a dorsal spine. Endopod with marginal articulate plumose setae, with hooked setae on distal lobe (Fig. 8a,b). Appendix interna with terminal hooked setae (Fig. 8c,d). Appendix masculina reaching approximately half of appendix interna, with terminal articulated plumose setae (Fig. 8c). Telson long, sulcate on almost its entire length, with eight terminal cuspidate setae of different sizes, those outers ones are bigger (Fig. 8e).
