This species was described from an immature female, measuring about 8.0 mm (head to end of inner ramus of U3), from the north-east Atlantic, off Portugal (41°29’N 15°44’W), Princesse Alice II stn. 2882, 0–2000 m, 10 August 1909. The unique holotype is in the MOM (372131). Material examined. Female in poor condition (ZMUC CRU-20428); South China Sea (06°55’N 114°02’E), Dana stn. 3688 III, 3000 mw, 8 April 1929. Mouthparts mounted on microscope slide, remainder in spirit. Diagnosis. Known only from immature female specimens, 4.5–9.0 mm. Pereon slightly inflated. Antennae 1 slightly shorter than head and first four pereonites combined; callynophore stout, with serrated margins. Antennae 2 reduced in length, slightly more than 0.2x A1, consisting of several elongate articles, the third is the longest. Gnathopod 1; basis length 0.7x remaining articles combined, 1.4–1.5x carpus; propodus length 0.8x (or more) carpus, armed with long, fine setae on both margins and medially; dactyl relatively straight, thin, length about onequarter propodus. Gnathopod 2 similar to G 1 in length and structure; basis length 0.7x remaining articles combined, 1.6–1.8x carpus; propodus slightly longer than carpus; dactyl as for G1. Pereopods 3 & 4 similar in length and structure; basis length 1.5–1.6x merus; merus broadened distally with antero-distal corner produced over carpus; carpus slightly longer than merus; propodus sub-equal in length to carpus; dactyl very short, thin, slightly curved. Pereopods 5–7 all relatively long and slender, with thin articles, and very small, fully retractile dactyls. Pereopod 5; length 1.4x P4; basis length 1.4–1.5x merus; carpus length slightly more than 0.6x ...
