Stomias longibarbatus (Brauer, 1902)

( Fig. 11B )

Diagnosis. Stomias longibarbatus differs from congeners by an extremely elongated chin barbel, 6–11 times longer than head length and up to 75% SL; body length 20-35 times body depth; IC>170; OA>135; VAV 58–73; total vertebrae 164–172 (Morrow, 1964d; Shcherbachev, Novikova, 1976; Kenaley, Stewart, 2015f; Sutton et al., 2020).

Geographical distribution. Circumglobal, between 43ºN and 38ºS (Shcherbachev, Novikova, 1976; Gibbs, 1986b, 1990b; Mundy, 2005; Kenaley, Stewart, 2015f; Cherel et al., 2020; Sutton et al., 2020). In the western Atlantic, the species is reported from off United States, the Gulf of Mexico, Brazil, and Uruguay (McEachran, Fechhelm, 1998; Harold, 2003; Moore et al., 2003; Nión et al., 2016; Judkins, Haedrich, 2018). In Brazil, S. longibarbatus was reported from off the Fernando de Noronha Archipelago (Judkins, Haedrich, 2018). It is reported here based on specimens collected off Rio Grande do Norte State (near the seamounts), the Rocas Atoll, and the Fernando de Noronha Archipelago, between depths of 260 and 1,020 m ( Fig. 7E ).

Specimens examined. 5 (173–390 mm SL): NPM 4390, 1 (390 mm), AB2#49A; NPM 4598, 1 (173 mm), AB2#56B; NPM 4599, 1 (272 mm), AB2#50A; NPM 4600, 1 (304 mm), AB2#58A; NPM 4601, 1 (267 mm), AB2#52B.
