Yirrkala gjellerupi (Weber & de Beaufort, 1916), unknown since the brief and unfigured original description of the holotype from New Guinea, is herein diagnosed, described, and illustrated, based on specimens recently captured in a Fijian freshwater stream. Other eels collected there and nearby include Anguilla megastoma, A. obscura, Lamnostoma kampeni, and an unidentified moringuid. Living far from the sea is very atypical for an adult ophichthid.
