Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

This species is distinguished from its congeners by the following set of characters: straight anterior margin of the mesethmoid (vs. medial notch); smooth and straight ventral surface of the premaxilla (vs. having bony knobs on the ventral surface of premaxilla); absence of teeth on the dentary (vs. presence of teeth on dentary); vertebrae anterior to anal-fin pterygiophore with single ventral processes (vs. paired process); having elongated mental filaments, barbel-like structures on the ventral surface of the adult head and cleithrum (vs. small papillous structures in the ventral surface of the adult head); and 8 anal-fin rays (vs. 6 or 7) (Ref. 128006).

Found in medium-sized stream, mostly slow flowing white waters running over sand mixed with riffles of fast flowing waters over pebbles (Ref. 128006).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
