Etymology: Gymnoamblyopus: Greek, gymnos = naked (or bare) + Greek, ambly = dark + Greek, pous = feet (or for Amblyopus, the generic basis of the subfamily name; referring to the absence of the scales of the fish; masculine Ref. 45979).; novaeguineae: From the type locality, the island of New Guinea; noun in apposition.
