Diagnosis. Astronesthes gudrunae differs from congeners by the AC with 1–2 elevated photophores; IV forming an arch below the pectoral-fin base; the presence of an aggregation of luminous tissue above the pectoral-fin, larger than eye and longitudinally oriented; three luminous spots on upper jaw, the first largest and anterior to orbit; IC 51–53; OA 32–33; PV 2 and 3 at the same level; chin barbel without a terminal bulb (Parin, Borodulina, 2002; Sutton et al., 2020).

Geographical distribution. Previous records of Astronesthes gudrunae are mostly restricted to the North Atlantic, south to 40º N , including the Caribbean Sea , with a single record in the eastern North Atlantic, at 22°1’N, 32°8’W (Parin, Borodulina, 2002, 2003; Judkins, Haedrich, 2018; Sutton et al., 2020) GoogleMaps . Astronesthes gudrunae is reported for the first time in the Brazilian EEZ based on one specimen collected off Rocas Atoll, at 610 m depth ( Fig. 7B View FIGURE 7 ), which also represents the southernmost record of the species known so far (about 3º S) .

Specimen examined. 1: NPM 4802, 1 (111 mm), AB2#53A.
