Chart showing the geographical distribution (white circle) in the seas surrounding the Antarctic continent.
Nota: In this chart the area frequented by whaling vessels has been hatched. The Antarctic circle (66°.5 S) has been drawn as a broken line. The numbers I to VI refer to the sectors into which the Antarctic seas are divided according to Mackintosh (1942) (after Vervoort, 1951).

For Park (2000, p.124), the species has a circumantarctic distribution. Besides the type locality (Farran1929), Vervoort (1951) found this species at 66° S57) betweejn 66°30' S and 47°43' S and between 54°16' E and 164 °29' E in the Indian Ocean sector of the Antarctic.; Park (2000) at 60°42' S, 59°48' W in the Drake Passage., 11° W in the Atlantic sector of the Antarctic; Vervoort (19

Bradford (1971 b) ne suit pas l’opinion de Vervoort (1957) sur une synonymie possible entre cette espèce et H. autrinus.
Séret (1979) précise les caractères de la P5 du mâle qui est décrit plus complètement par Park (2000). D"après l'auteur, Bradford distingue H. pustulefer d'H. pacificus d'après la longueur de la soie terminale du segment 3 de l'exopodite de la P5 droite. Si on se base sur la longueur de cette soie, le spécimen des Kerguelen devrait être identifié à H. pacificus. Cependant, la taille et la structure de la P5 gauche sont identiques à celles d'H. pustulifer d'après Bradford (1971). En effet, l'endopodite de la P5 gauche dépasse le niveau d'insertion des épines externes et internes du segment 3 de l'exopodite de la P5 gauche chez H. pustulifer, tandis que le même endopodite se termine au niveau de ces épines chez H. pacificus (Brodsky, 1950).
