Remarks

meso-bathypelagic; 500-1000 m. In vertical tow 4000-3000 m (Harding, 1974). 400-1000 m (in Bode & al., 2017). In horizontal tow from 2000 m off Malta.
For Grice & Hulsemann (1965, p.231) the presence of integumental spines is apparently a variable character as some specimens were entirely devid of them. Vervoort (1946) noted that the spinulation of the integument in his eastern Pacific specimens also varied.
Schulz (1989, p.189) points to the females agree with Damkaer (1975) and Park (1970) except that the distal outer spine of exopodal segment 1 of P1 is distinctly smaller than that of exopodal segments 2 and 3.
After Lapernat & Razouls (2002, p.19) the value of the Itoh's index are for masticatory edge of the left Md (442.1, number of teeth: 8) and for masticatory edge of the right Md (396.1, number of teeth: 9).
