Etymology: Etmopterus: Greek, ethmos, -ou = sieve or ethmoides bone + Greek, pteron = wing, fin (Ref. 45335). More on author: Smith.
Research shows that this species is restricted to northwestern Pacific ; Austral-Indonesian records are considered to represent two or three undescribed species (see Ref. 87957); distribution will be resolved (linked to correct species) when publications are received.
