Etymology: osseensis: Named in honour of Prof. Dr. J.W.M. Osse, who initiated, together with F.A. Sibbing, the research on the Lake Tana Barbus species (Ref. 35836).
Eponymy: Dr Jan W M Osse (d: 1935) is a Dutch zoologist who studied biology at Leiden (1961) and was a member of the scientific staff there (until 1971). [...] (Ref. 128868), visit book page.

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
A small-sized, deep-bodied species, sometimes with a slight nuchal hump (Ref. 35836). A stiff lower jaw, tapering towards a narrow, hypertrophied distal tip, covered with thick skin (Ref. 35836). The protruded mouth does not form a cylindrical tube (Ref. 35836). Long dorsal spine, 19-27% of SL (Ref. 35836). Anal and ventral fins are rather long, 19-24% and 18-21% of SL respectively, with a rather short pectoral-ventral length, 22-26% of SL (Ref. 35836). The caudal peduncle is deep, 11-12% of standard length (Ref. 35836). Scales: 12-14 predorsal scales (Ref. 35836). Live specimens are rather dark greenish brown, the back being darker, with usually greenish fins (Ref. 35836). In alcohol the basic color is a dull yellowish brown, the back being darker (Ref. 35836).
Body shape (shape guide): fusiform / normal.
Labeobarbus osseensis especially occurs near rocky substrates in water of less than 3 m deep (Ref. 35836). It feeds on adult insects and macrophytes (Ref. 35836).
