Morphology | Morphometrics
This species is distinguished from its congeners by the following set of characters: thin, deciduous skin; color silvery pink to pale brownish; preopercular and oral lateral line canals sharing a common branch; short dorsal spine, subequal or slightly shorter than first dorsal fin; claspers of adult males long (17-19% BDL), trifurcate, divided for slightly less than half of their length; structure of the CO1 gene (Ref. 76965).
