Aristostomias tittmanni Welsh, 1923

(Fig. 12B)

Diagnosis. Aristostomias tittmanni differs from congeners by the presence of 6–7 pectoral-fin rays; 15–19 PV photophores in 5–6 close-set groups of 2–4 photophores each; luminous dots between eye and postorbital organ; barbel with a well-defined bulb (Morrow, 1964c; McEachran, Fechhelm, 1998; Sutton et al., 2020).

Geographical distribution. Atlantic (Morrow, 1964c; McAllister , 1990; Porteiro et al., 1999; Harold , 2003; Béarez et al., 2017; Carneiro et al., 2019; Sutton et al., 2020) and Pacific oceans ( Pequeño , 1989; Mundy , 2005). In the western Atlantic , the species is reported from off Canada, United States, French Guiana, and northeastern Brazil (off Maranhão State) ( McEachran , Fechhelm , 1998; McAllister , 1990; Judkins , Haedrich , 2018; Ramírez et al., 2019). Aristostomias tittmanni is reported here based on four specimens collected off Paraíba State, the Rocas Atoll , and the Fernando de Noronha Archipelago , between depths of 50 and 800 m ( Fig. 7F ) .

Specimens examined. 4 (32–76 mm SL): NPM 3278, 1 (39 mm), AB1#12; NPM 4595, 1 (32 mm), AB2#45B; NPM 4596, 1 (37 mm), AB2#21; NPM 4662, 1 (76 mm), AB2#42A.
