Remarks. We have not observed notable variations in the morphological characteristics of this species. However, the facial pterygostomian spine is minute or obsolescent in some specimens. The genetic divergences between G. ohshimai and all other sequenced related species are larger than 15.0% (COI), and 8.6% (16S rRNA) ( Tab. 1).

Distribution. Palau, Hong Kong, Indonesia, Papua New Guinea, Australia (Queensland), Vanuatu, New Caledonia; 0–48 m, in corals and rubble.
