Abstract

A new species of eel cods Muraenolepis trunovi sp. nova (Muraenolepididae) from the Lazarev Sea is described. The type specimen is caught at the depth 730–860 m. The new species differs from all known species in very elongated first dorsal and pectoral fins. With respect to the body proportions and the number of rays in the second dorsal fin and the anal fin, it is related to M. marmorata but clearly differs from the latter in a greater number of vertebrae (73 vs. 67–69), in the reduced upper lateral line (to one sensory tube), and in complete absence of the lower lateral line on the body. The lectotypes of Muraenolepis marmorata Gunther, 1880 (British Natural History Museum, BNHM) and M. marmoratus microps (Lonnberg, 1905) (Naturhistoriska Riksmuseum, NRM) are redescribed.
