Gymnocranius oblongus (Teleostei: Lethrinidae), a new large-eye bream species from New Caledonia

Abstract : Gymnocranius oblongus is described as a new species of the subfamily Monotaxinae (Sparoidaea : Lethrinidae), a group of commercially important fishes distributed throughout the Indo-West Pacific, from six specimens collected in New Caledonia. It is characterized by an oblong, fusiform body, slightly rounded snout, elongate tail with rounded tips and sub-horizontal, wavy blue lines or dashes on snout and cheeks. It is distinct from sympatric G. grandoculis by a more slender body which is also more symmetrical dorso-ventrally, and a more elongated caudal fin. Both mitochondrial-DNA and nuclear-DNA markers provide a genetic basis to the distinction of G. oblongus from G. grandoculis.
