Diplophos australis Ozawa, Oda & Ida, 1990

( Fig. 2A )

Diagnosis. Diplophos australis is distinguished from congeners by the presence of 84–91 vertebrae; 12–13 gill rakers; 61–67 anal-fin rays; IV 41–44; OA 80–87; IC 99– 105 (Ozawa et al., 1990; Koeda, Ho, 2019).

Geographical distribution. South Atlantic and South Pacific oceans, between 20ºS and 40ºS (Ozawa et al., 1990). In the South Atlantic, D. australis was reported from off

Brazil, South Africa, Saint Helena, Ascension, and Tristan da Cunha islands (Ozawa et al., 1990; Judkins, Haedrich, 2018). In Brazilian waters, the species was previously reported from off São Paulo to Rio Grande do Sul States (Figueiredo et al., 2002; Menezes et al., 2003; Judkins, Haedrich, 2018). The specimens reported here, collected from off Fernando de Noronha Archipelago at depths between 780 and 850 m, represent the northernmost record of the species in the Atlantic Ocean (about 3º S; Fig. 3A ) .

Specimens examined. 3 (71–99 mm SL): NPM 4564, 2 (75–99 mm), AB2#42A; NPM 4920,

1 (71 mm), AB2#44A.
