Abstract: Dicrolene nigricaudis (Alcock, 1899), a rare species of deep sea cusk eel described from Andaman Sea and Arabian Sea in 1899 is redescribed and compared with its closely related species, D. tristis in terms of meristics and morphometrics in order to establish its individual taxonomic identity. The specimens were collected during the fishery survey cruises of FOR V Sagar Sampada along the continental slope of Indian EEZ. D. nigricaudis is characterized by two median and a pair of basibranchial tooth patches and lower elongated free rays of pectoral fin. The paper highlights the taxonomic characters useful for species identification.
