Etymology: Labeo: Latin, labeo = one who has large lips (Ref. 45335); batesii: batesii: species name dedicated to G.L. Bates who collected the type material (Ref. 26190). More on author: Boulenger.

Morphology | Morphometrics
Vertebrae: 31 - 33. Diagnosis: snout rounded with deep transverse furrow; scale formula: 37-39 (38 commonly observed); 4.5-6.5 (5.5 commonly observed, exceptionally 4.5); 3.5-4.5 (4.0 commonly observed); 16-20 (16 commonly observed); dorsal fin with 10-11 (10 commonly observed) branched rays; upper edge of dorsal fin always concave; 32-33 (32 commonly observed, exceptionally 31) vertebrae; ventral fin origin located under the 4th branched dorsal ray; genital opening close to anal fin origin; rarely a longitudinal band, but if present unflared (Ref. 81639).
Young specimens (up to 2.5 cm SL) are recorded from the Benito River in Cameroon (Ref. 1440). Most of the individuals examined were collected from areas with rapidly flowing water (Ref. 26190). Maximum TL recorded: 19.0 cm (Ref. 2801).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00299 - 0.01530), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (41 of 100) .
