Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 20 - 21; Spine anali: 3; Raggi anali molli: 16 - 18; Vertebre: 26. This species is distinguished by the following characters: modally 21 segmented dorsal-fin rays; modally 17 segmented anal fin rays; with a relatively long LL (1.6-1.9, mean = 1.8) in SL; relatively well-developed scalation on the interorbital, suborbital and dentary; head length 2.4-2.7 in SL, peduncle depth 3.2-4.0 in HL (Ref. 116906)
