Distribution map of Heterorhabdus paraspinosus by geographical zones
Loc:
Sub-Antarct. (S Tasman Sea), off W South Africa, S off Chilean coast.

Type locality: 14,32°27' S, 08°49' E.

Park (2000, p.132) found the species from the west coast of South Africa in the southeastern Atlantic between 33°47' S and 31°09' S; from off the Chilean coast at 46°55' S, 75°50' W; in the Tasman Sea at 49)39' S, 152°34' E. This species seems to be restricted in distribution to the coastal waters of the subantarctic coastal waters.
