Manducus maderensis (Johnson, 1890)

( Fig. 2C )

Diagnosis. Manducus maderensis differs from Manducus greyae (Johnson, 1970) by the number of anal-fin rays (36–41 vs. 58–59); number of OA photophores (45–48 vs. 50– 54); number of IC photophores (70–75 vs. 84–86); number of photophore series along lateral line (65–68 vs. 76–78); total vertebrae (61–63 vs. 76) (Grey, 1964; Johnson, 1970).

Geographical distribution. Atlantic Ocean, from 40ºN to 30ºS (Smith et al., 1991; Figueiredo et al., 2002; Sutton et al., 2020). In the western Atlantic , the species is reported from off United States to southeastern Brazil, including the Gulf of Mexico and the Caribbean Sea (Smith et al., 1991; McEachran, Fechhelm, 1998, Harold, 2003). The species was previously recorded off Rio Grande do Norte and Paraíba States , and from Bahia to Rio de Janeiro States , Fernando de Noronha Archipelago , Rocas Atoll , and the Vitória-Trindade Chain (Davis Seamount) in Brazilian waters (Mukhacheva, 1978; Smith et al., 1991; Figueiredo et al., 2002; Menezes et al., 2003; Braga et al., 2007; Costa, Mincarone, 2010; Pinheiro et al., 2015; Judkins, Haedrich, 2018). Additional records outside the Brazilian EEZ are known along the western South Atlantic (Smith et al., 1991). Manducus maderensis is reported here based on specimens collected off the Rocas Atoll and Fernando de Noronha Archipelago , between depths of 90 and 615 m ( Fig. 3A ) .

Specimens examined. 3 (42–65 mm SL): NPM 3259, 1 (42 mm), AB1#22; NPM 4122, 1 (65 mm), AB2#50A; NPM 4530, 1 (63 mm), AB2#49B.
