Etymology: Pseudobagrus: Greek, pseudes = false + Mozarabic bagre, Greek, pagros = a fish, Dentex sp. (Ref. 45335); brachyrhabdion: Derived from the Greek brachys (short), and rhabdion (barbel), in reference to the length of the maxillary barbel, which is shorter than in other related species..

Korte beschrijving
Morfologie | Morfometrie
Dorsale stekels (totaal): 1; Dorsale zachte stralen (totaal): 7; Anale zachte stralen: 20 - 23. Differs from all congeners with a similar caudal-fin shape (truncate or slightly emarginate) by the following unique combination of characters: supraoccipital plate and nuchal plate broadly interspaced and covered with skin; nasal barbels only at most reaching anterior margin of eye; maxillary barbels reaching slightly beyond posterior margin of eye; outer mandibular barbels reaching posterior margin of eye; dorsal fin with a slightly convex distal margin, origin nearer to pectoral-fin insertion than to pelvic-fin insertion; dorsal-fin spine shorter than pectoral spine, with a slightly serrated posterior margin; pectoral-fin spine with a smooth anterior margin; anal fin with 20-23 rays, base length 23.8-32.0% SL, posterior end of anal-fin base anterior to posterior end of adipose fin base; no longitudinal black band extending along flank;
eyes large, diameter 16.3-23.7% HL; and vertebrae 5 + 43-46 (Ref. 75714).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00383 - 0.01980), b=2.95 (2.78 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
