Korte beschrijving
Morfologie | Morfometrie
Dorsale stekels (totaal): 15 - 17; Dorsale zachte stralen (totaal): 7-9; Anale stekels 5-6; Anale zachte stralen: 6 - 7; Wervels: 26. Differs from all species of the genus by the following combination of characters: 5-6 anal-fin spines; 6-7 branched anal-fin rays; caudal peduncle length 8.9-11.8% of SL; lips not thickened; in preserved specimens lateral band formed by two series of scales, each scale bears a dark spot in the centrum, between both scales there is a light narrow area; dorsal, anal and caudal fins, and opercle without dark spots (Ref. 57794).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
