Espèce Heterorhabdus spinifer - Carte de distribution 3
Carte de 1996
Loc:
South Africa (E & W), off NE Tristan da Cunha, Caribbean Sea, Caribbean Colombia, G. of Mexico, off Bermuda (Station "S"), Sargasso Sea, off Delaware, W Medit. (in Kovalev & Shmeleva, 1982, p.84), Natal, S Indian (E-W), S Pacif. tropical (E-W), off NE New Zealand.

Locality type: Caribbean Sea and Gulf of Mexico.

For Park (2000, p.109)The species has a circumglobal distribution. In the Indo-Pacific, the species seems to be restricted mainly to the southern tropical regions, while it occurs widely in the Atlantic.
