| Summary: | Leptoderma macrophthalmum sp.n. (Fig. 2–3) Holotype. NORTH ATLANTIC, 42o47’ N – 29o38’ W, 8 July 2004, 2107– 2063 m gear depth, soft bottom, R/V “G. O. Sars”, super station 42, local station 368, ser. 1150, bottom trawl (shrimp trawl). ZMUB 19686. Diagnosis. The species differs from three of the four other congeneric species (L. affinis, L. macrops and L. retropinna) by having a distinct gap between the posterior ends of the dorsal and anal fins and the beginning of procurrent caudal finrays. This gap is absent in the three species mentioned, but present in the fourth (L. lubricum), from which L. macrophthalmum differs by having a lack of dermal papillae along the lateral line, pectoral fins lower on body, a larger eye relative to head dimensions, and a shorter pre-dorsal length. Description. SL 151 mm, fresh weight 16 g. Dimensions as per cent of SL as follows: Pre-dorsal length 49.3, pre-anal length 45.7, pre-pelvic length 39.5, dorsal fin base 31.1, dorsal procurrent caudal fin section 15.5, anal ... : Published as part of Byrkjedal, Ingvar, Poulsen, Jan Yde & Galbraith, John, 2011, Leptoderma macrophthalmum n. sp., a new species of smooth-head (Otocephala: Alepocephalidae) from the Mid Atlantic Ridge, pp. 49-56 in Zootaxa 2876 on pages 51-54, DOI: 10.5281/zenodo.277564 ... |
