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).

Description

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 ).
