Carte 5 issued from : W. Vervoort in B.A.N.Z. Antarctic Reseach Expedition, Reports - Ser. B, Vol. III, 1957 [Fig.124]
Chart showing the geographical distribution (white triangle) 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).

Remarques

méso-bathypélagique.
Sampling depth (Antarct., sub-Antarct.) : 200-600 m.
Pour Sewell (1932; 1948) les deux espèces seraient synonymes. Seules les dimensions permettent de distinguer cette espèce de H. longicornis. Des confusions ont été possibles avec Heterostylites nigrotinctus, d'où certaines localisations contestables. Park (2000) et Ohtsuka & al. (1997, p.593: Notes) ne sont pas en accord sur la synonymie entre cette espèce et Heterostylites nigrotinctus.
Certaines localisations nécessitent confirmation (Park, 2000)
