 Diagnosis. A species of Pseudocaranx with posterior margin of upper jaw canted posteroventrally (fig. 1A); lachrymal and expanded part of maxilla densely covered with scales; caudal vertebra 14; gill rakers 10–15 upper, 24–28 lower, 35–43 total; scales in curved part of lateral line 37–48.   
 Distribution. Endemic to Australia (fig. 4); eastern Bass Strait extending W at least to Rottnest I., WA. A single collection of P. wrighti from Exmouth Gulf (see material examined) at approximately 22˚S extends its distribution well into that of P. dinjerra, if the record is not due to a specimen mix-up.   
 Remarks. This species differs from other Australian congeners as indicated in the identification key and Table 3. It also differs in having a well defined opercular spot that is nearly solid black and approximately the diameter of the pupil (fig. 3D), in never developing a yellow mid-lateral body stripe, and second dorsal and anal fins transparent or dusky green, never with yellow pigmentation. Pseudocaranx wrighti is the smallest species of Pseudocaranx, rarely exceeding 200 mm FL.
