Morphology | Morphometrics
This species is distinguished by its relatively deep and compressed body and head, with greatest body width about 2 times into greatest depth; suborbital depth about 3.5 into orbit diameter; 5.5 scale rows below origin of second dorsal fin (Ref. 83327). It is has blunter head profile with barely protruding, short and not spatulate nasal bones, and these characters are considered plesiomorphic in respect to the other members of the genus (Ref. 98298)..
