Plate 2 issued from : O. Tanaka & M. Omori in Publs Seto Mar. Biol. Lab., 1974, XXI (3/4). [p.265, Fig.33].
Female: a, forehead (dorsal, rostrum underneath); b, idem (lateral); c, last thoracic segment and urosome (dorsal); d, idem (lateral left side); e, A2; f, Md (mandibular palp); g, Md (mandibular teeth); h, rostrum (frontal view); i, Mx1; j, Mx2; k, Mxp; l, P1; m, P2; n, P3; o, P5.

Remarks

meso-bathypelagic. Known to occur below 1200 and above 600 m depth (Matthews, 1972). Sargasso Sea: 1500-2000 m (Deevey & Brooks, 1977, Station "S");
Sampling depth (Antarct., sub-Antarct.): 100-600 m.
Park (1988, p.4) points to the species distribued widely between 34°S and 74°S (ice shelf) n the Pacific Ocean sector and between 50° and 64°S in the Indian Ocean sector.
