Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Dorsale zachte stralen (totaal) : 7; Wervels: 29. Distinguished by the color pattern with a dark blotch beneath adipose fin not extending to anal fin and by the high number of anal fin proximal radials, 12, shaped as rod-like thin tubes, the last one bearing a laminar extension. Can be diagnosed by the following combination of characters: a pectoral fin spine with a bony point and bearing proportionally few serrations on posterior border of pectoral fin spine, eight to ten; seven pleural ribs and a proportionally short head width (67.8-74.3% in HL).
