Remarks

"Abyssalis" Group.
meso-bathypelagic.
Sampling depth (Antarct., sub-Antarct.) : 0-600 m.
According to Vervoort (1951, p.128) this species is characterized by the tubercle on the dorsal surface of the genital segment of the abdomen, but for the rest resembles H. austrinus, norvegicus and abyssalis. The outer edge spine on the 2nd exopodal segment of female P5 is slightly shorter than the 3rd exopodal segment; in Farran's specimens they are of the same length.
Bradford (1971 b) does not follow up on the opinion of Vervoort (1957) regarding a possible synonymy between this species and H. autrinus. Bradford (1971 a, p.128) noted that one male of H. pustulifer, taken in the Ross Sea (at 75°09'S, 171°W) was incorrectly identified as H. austrinus.
Séret (1979) specifies the characters of the male P5 that is described more detailed by Park (2000, p.124).
