Coelorinchus anisacanthus Sazonov, 1994	Central Pacific
Coelorinchus aratrum Gilbert, 1905	Central Pacific
Coelorinchus braueri Barnard, 1925	Off South Africa	Specimens from seamounts in southwestern Indian Ocean at 25° S and from off South African coast and Agulhas show slight morphometric and structural differences and require thorough comparison.

Coelorinchus doryssus Gilbert, 1905	Central Pacific
Coelorinchus gilberti Jordan and Hubbs, 1925	Japan to Taiwan	Coelorinchus kanetomoi Matsubara and Asano, 1943 is a synonym (Okamura 1970a).
