Photostomias atrox (Alcock, 1890)

(Fig. 12E)

Diagnosis. Photostomias atrox differs from congeners by the presence of three pairs of basibranchial tooth patches; 22–26 dorsal-fin rays; 26–30 anal-fin rays; sum of dorsal- and anal-fin rays 47–55, usually 50-54; male PO moderate to large in specimens greater than 60 mm, 72.1–197.2% fleshy orbit, 16.7–46.6% jaw length; AO large in specimens greater than 60 mm, 9.2–37.8% fleshy orbit, 2.1–9.6% jaw length (Kenaley, Hartel, 2005; Sutton et al., 2020).

Geographical distribution. Circumglobal in tropical and subtropical waters, except the eastern Pacific Ocean (Kenaley, Hartel, 2005; Kenaley, 2009; Sutton et al., 2020). In the western Atlantic , the species is reported from off the United States to Brazil (Kaneley, Hartel, 2005; Hartel et al., 2008). In Brazil the species was recorded off the Trindade and Martin Vaz Archipelago , with additional records outside the EEZ off the north portion of the country and the Saint Peter and Saint Paul Archipelago (Kenaley, Hartel, 2005; Sutton et al., 2020). Photostomias atrox is reported here based on one specimen collected off Pernambuco, at 680 m depth ( Fig. 7F ) .

Specimen examined. 1: NPM 4575, 1 (67 mm), AB2#16.
