Etymology: Kneria:From Kner, that studied fishes in the Imperial Museum of Vienna, with Jean Natterer (1817) (Ref. 45335); uluguru:Named for the Uluguru Mountains, Tanzania, where the fish have first been collected; a noun in apposition (Ref. 26644). Eponymy: Dr Rudolf Kner (1810–1869) was an Austrian zoologist specialising in ichthyology. [...] This is a toponym referring to the Uluguru Mountains in Tanzania, where the species appears to be endemic. (Ref. 128868), visit book page.
Africa: restricted to the Upper Ruvu drainage on the eastern and possibly southeastern slopes of the Uluguru mountains, Tanzania (Ref. 26644). 非洲: Ruvu 流域， Uluguru 山，坦尚尼亞上游。

成熟度: Lm? range ? - ? cm Max length : 4.3 cm SL 雄魚/尚未辨別雌雄; (Ref. 26644)
背棘 (總數) : 0; 背的軟條 (總數) : 9 - 10; 臀棘: 0; 臀鰭軟條: 9 - 11. Diagnosis: small species with long head, 18.8-25.0% SL; snout relatively long, 28.6-37.0% SL, with narrow cleft and peculiar structure of the inferior positioned mouth; opercular disc of males shallow, with rounded outer edge; pectoral fin long, 14.9-17.7% SL; preanal length relatively short, 65.0-71.9% SL; 79-87 lateral line scales, which tends to increase with increasing length of the fish; distinct blackish streak from tip of snout to caudal fin, which may be coverd by dark bluish spots; dorsal fin origin clearly behind pelvic fin origin (Ref. 26644).
Body shape (shape guide): elongated; Cross section: circular.
Maximum total length recorded is 5.31cm TL; inhabits clear streams and rivers with very fast current to more gentle waterflow, but more numerous in the quieter stretches; omnivorous, but feeds mainly on algae and aufwuchs rasped off from stones; apparently no marked spawning season (Ref. 26644).
