mean 54-55 % SL; branched dorsal fin rays 7, tips of paired fins formed by second to third branched rays; caudal fin with straight to very weakly emarginated distal margin; vertebrae 40-44, modally 38; body scaled; dark pattern on body consists of irregular blotches often confluent into short transverse bars or longitudinal band along lateral line, no distinct dorsal saddles; peritoneum brownish, becoming paler with mottles ventrally (Ref. 133452).
