Barathronus linsi Nielsen, Mincarone & Di Dario, 2015 Table 2. Figs. 1, 13–14 Barathronus linsi Nielsen et al. , 2015: 55 (type locality: 4°25.83’S, 36°37.38’W). Material examined : Holotype. MNRJ 41723, SL 101 mm, male, Potiguar Basin, off Northeast Brazil, 4°25.83’S, 36°37.38’W to 4°25.87’S, 36°36.48’W, RV Seward Johnson, st. ArMT84, bottom trawl, 1964–2045 m, 5 June 2011. Diagnosis. Barathronus linsi differs from the other four Barathronus species with a transparent peritoneum by the following combination of characters: dorsal-fin rays 78, anal-fin rays 69, pectoral-fin rays 21, precaudal vertebrae 33, total vertebrae 78, eight fangs on vomer, long rakers on anterior gill arch 25, predorsal length 42% SL, pair of bulbs at base of penis absent and with a ventral flexure of anterior vertebrae. Newly caught specimen overall yellowish to white reddish and lack of black pigment both in skin and peritoneum. Otolith oval, 1.7 times as long as thick and with small centrally placed undivided sulcus (fig.14). Description. Only the holotype is known. For a detailed description see Nielsen et al. (2015: 55). The principal meristic and morphometric characters are shown in Table 2. Comparisons. Barathronus linsi seems most similar to B. affinis but differs by having more fangs on vomer (8 vs. 2) and more long gill rakers (25 vs. 20). Distribution (Fig. 1) Caught in a bottom trawl at 1964–2045 m in Potiguar Basin, off Northeast Brazil. : Published as part of Nielsen, Jørgen G., 2019, Revision of the circumglobal genus Barathronus (Ophidiiformes, Bythitidae) with a new species from the eastern North Atlantic Ocean, pp. 231-256 in Zootaxa 4679 (2) on pages 243-244, DOI: 10.11646/zootaxa.4679.2.2, http://zenodo.org/record/3772453 : {"references": ["Nielsen, J.
