Diagnosis: fronto-parietal fontanel absent in adults, sometimes pore-like in juveniles, disappearing with growth; dorsal fin origin at about same level as pelvic fin insertion; sexual dimorphism affecting anal fin shape; 24-34 lateral line scales; 5.5 scales between lateral line and dorsal fin; 10-15 anal fin branched rays; 14-20 gill rakers on lower limb of first gill arch; 8 teeth in outer premaxillary row (Ref. 2880, 80290, 81279). Snout short, more than 3x head length; head length/snout length 3.6-4.3; 10-11.5 predorsal scales; flanks without lateral band; adults medium-sized (Ref. 80290).
