Abstract

In 2010, the French expedition “Atimo Vatae” caught a specimen of the ophidiid genus Neobythites off southern Madagascar at a depth of 285 m. The specimen is different from all the 12 species known from the westernmost Indian Ocean, but it fits the diagnosis of N. bimarginatus Fourmanoir & Rivaton, 1979, one of the 30 Neobythites species known from the East Indian and West Pacific Oceans. N. bimarginatus is unique by having the distal and proximal parts of the dorsal and anal fins light with a black middle part. It is known from 13 specimens from off New Caledonia and a few neighbouring islands, which is more than 10,000 km from Madagascar. More exploratory sampling is necessary on the upper part of the continental slope to obtain a correct picture of the distribution and population structure of N. bimarginatus.
