Abstract

A new species of Conger eel is described from a single specimen (569 mm total length) collected off Kanyakumari, Southwest coast of India, Arabian Sea. The following characters distinguish the new species from other congeners: dorsal-fin origin behind the pectoral-fin tip; head larger, 18.5% TL; longer predorsal length 24.0% TL; relatively shorter trunk, uniserial teeth at the posterior end of vomerine patch; body blackish to dark brown; pectoral fin completely darker; cephalic pores rim whitish; SO pores 3; IO pores 6; pectoral rays 19; total vertebrae 141+. Genetic analysis of the mitochondrial COI gene revealed that the new species is closely related to Conger verreauxi Kaup, 1856 and Conger macrocephalus Kanazawa, 1958, with a genetic divergence of 5.7% and 5.9% respectively.
