| Summary: | Sternoptyx pseudodiaphana Borodulina 1977 (Fig. 2 G; Table 3) Material examined. 2 specimens (34.0– 46.1 mm SL): MNRJ 30348, 1(34.0 mm), AG 2-14; MNRJ 30359, 1(46.1 mm), AG 2-13.2. Diagnosis. Sternoptyx pseudodiaphana can be differentiated from its congeners by the following combination of characters: SAN photophore positioned at approximately 3 or less times in trunk depth, not more than 3.5 times in sub-adults; trunk depth subequal to trunk length; vertebrae 30–32, rarely 29; dorsal-fin rays 9–13, usually less than 12; pectoral-fin ray bases pigmented in juveniles; dorsal-fin base usually smaller than dorsal-blade base, occasionally equal. Meristic description. Fin rays: D 11–12; A 14; P 1 10; P 2 5. Gill rakers: 7–8 (4–5 + 1 + 2–3). Photophores: BR 5; I 5; AB 10; PAN 3; AN 3; SC 4. Distribution. Widely distributed in Southern Ocean and associated boundary currents in Southern Hemisphere, between 20 ° and 50 °S. Remarks. These specimens represent the first records of S. pseudodiaphana in the western South Atlantic. Published as part of Lima, Adriano T., Costa, Paulo A. S., Braga, Adriana C., Nunan, Gustavo W.
