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; P1 10; P2 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.
