Bathophilus pawneei Parr, 1927

( Fig. 13B )

Diagnosis. Bathophilus pawneei differs from congeners by the pelvic-fin origin close to, but slightly below, the body midline; 12–15 pelvic-fin rays; 2 pectoral-fin rays (rarely 1) in a single group; 14–17 dorsal-fin rays; 15–18 anal-fin rays; usually a small luminous spot behind the pelvic fin, and sometimes another luminous spot on the shoulder region; about 24–29 photophores in the lateral series (OV 11–14, VAL 13–15); about 36–42 photophores in the ventral series (IP 5, PV 12–15, VAV 13–15, AC 6–7) (Morrow, Gibbs, 1964; Barnett, Gibbs Jr., 1968; McEachran, Fechhelm, 1998; Sutton et al., 2020).

Geographical distribution. Atlantic, Indian, and Pacific oceans, from 45ºN to 27ºS (Morrow, Gibbs, 1964; Clarke, 1974; Gibbs, Barnett, 1990; Aizawa, 2002; Shinohara et al., 2009; Sutton et al., 2020). In the western Atlantic, the species is reported from off the United States to Brazil, including the Gulf of Mexico and the Caribbean Sea (Parr, 1927; Morrow, Gibbs, 1964; Parin et al., 1974; Gibbs, Barnett, 1990; McEachran, Fechhelm, 1998; Moore et al., 2003; Judkins, Haedrich, 2018). In Brazil the species was reported from off Fernando de Noronha and Saint Peter and Saint Paul archipelagos (Judkins, Haedrich, 2018; Sutton et al., 2020), with additional records outside the Brazilian EEZ off the Rio de Janeiro State (Gibbs, Barnett, 1990). Bathophilus pawneei is reported here based on specimens collected off the Rocas Atoll and Fernando de Noronha Archipelago, between depths of 430 and 610 m ( Fig. 14A ).

Specimens examined. 4 (30–124 mm SL): NPM 4571, 1 (81 mm), AB2#41A; NPM 4572, 1

(124 mm), AB2#40A; NPM 4928, 2 (30–32 mm), AB2#53B.
