| Specialized organs | no special organs |
| Different appearance | always different morphology between mature adults |
| Different colors | always different colors between mature adults |
| Remarks | Sexual dimorphism affecting shape of anal fin in males; adult males have dorsal fin rays filamentous; males larger than females; different colors in males and females (Ref. 80290). |

| Diagnosis |
Diagnosis: fronto-parietal fontanel narrow, pore-like, but present; head length/snout length 3.5; 34-35 lateral line scales; 5.5 scales between lateral line and dorsal fin; 13 predorsal scales; 18 anal fin branched rays; 12-14 gill rakers on lower limb of first gill arch; 6 teeth in outer premaxillary row (Ref. 80290). Description: pronounced sexual dimporphism affecting anal-fin shape in adult males; adults males have dorsal fin rays filamentous; like most of species in this groups, males are larger than females (Ref. 80290). Coloration: as all species of B. longipennis group (Ref. 80290). |
