More Info


Distribution

Houtman Abrolhos (possibly further south to Green Head) to North-West Cape, Western Australia. The species is rarely taken north of Shark Bay.

Features

Dorsal fin VIII + I, 23-25; Anal fin III, 19-21; Vertebrae 27-31, 14 caudal vertebrae; GIll rakers 7-10 + 19-21 = 27-31; Lateral-line scales 58-74, curved part 53-66, straight part 2-11. 
Upper jaw with posterior margin nearly vertical; lachrymal naked and expanded part of maxilla only partially covered with scales.

Fisheries

A pelagic species, trawled from depths of 43-60 m.

Similar Species

Pseudocaranx dinjerra differs from the Australian endemic P. wrighti in having the posterior margin of the upper jaw nearly vertical, lachrymal without scales, 19–21 versus 24–28 lower gill rakers and 53–66 versus 37–48 scales in the curved part of the lateral line. The new species is distinguished from Australian populations of P. georgianus and “dentex” primarily by having a different combination of meristic values including 14 versus 15 caudal vertebra, 19–21 versus 21–24 segmented anal-fin rays and 58–75 versus 72–95 total lateral-line scales Smith-Vaniz & Jelks 2006). 

Etymology

The specific name dinjerra is from the Aboriginal word "dinjerra", meaning west, in reference to the Western Australian endemic status of the species.
