Comments: A deep-water species collected by bottom long-line at depths (726?)900-1,225(1,568?) m by hooks baited with large pieces (about 4x3x2 cm) of giant Peruvian squid, <i>Dosidicus gigas</i>. Predatory species, which also opportunistically feeds as necrophage. Spawning probably take place in November - December. In post-spawning female (paratype, 31.5 cm TL, captured at 12 January 2010) the length, width and depth of ovary attain about 35-38, 11-12 and 6-7 mm correspondently. The GSI reaches about 0.8. State of gonad maturity, affirmed by presence of ovarian cavity and empty follicles, provide the evidence of post-spawning SGM VI-III and recently finished spawning. The diameter of 10 measured oocytes of trophoplasmatic growth of younger generation varied from 0.24 to 0.49 mm (average 0.37 mm, SD=0.08). Paired well developed testes of male (holotype, 29 cm TL, captured at 11 January 2010) reach about 45-49 mm in length, 12-14 mm in width and 3-4 mm in depth; GSI about 0.5; SGM apparently corresponds to early post-spawning stage VI or VI-II. In the smaller male (28 cm TL, captured at 20 January 2010) visual appearance of undeveloped testes (length 35, width 2.5, depth 1 mm) and low GSI (0.06), apparently corresponding to SGM II-III, evidence on subadult male, which could spawn for the first time the next season. Liver large, filling about 1/2-2/3 of the length of the abdominal cavity, creamy in coloration; hepatosomatic index reaches 2.4-6.4. A nematode larva of the genus <i>Pseudoterranova</i> sp. (family. Anisakidae) was found on the surface of the liver (Ref. 92304).
