Abstract

Luthulenchelys heemstraorum genus and species novum, subfamily Ophichthinae, tribe Ophichthini, is described from a 472 mm eel trawled off Durban, KwaZulu-Natal, South Africa, in 450–460 m. Luthulenchelys differs from all known ophichthids in having the following suite of characters: an extremely elongate body, long tail, dorsal-fin origin in anterior trunk region, an elongate pectoral fin, posterior eye/jaw location, blunt snout, posterior nostril within upper lip, slender dentition, a single vomerine tooth, uniquely developed lateral-line ossicles, and five gill arches, with a very reduced fifth ceratobranchial. Several changes in taxonomy are proposed: Ophisurus lumbricoides Bleeker 1853, Ophisurus rutidodermatoides Bleeker 1853, and Ophichthus derbyensis Whitley 1941 are junior synonyms of Ophichthus rutidoderma (Bleeker 1853); Sphagebranchus lumbricoides Bleeker 1864 is a species of Yirrkala.
