Diagnosis. Garra tengchongensis can be easily distinguished from its congeners with a proboscis in the Irrawaddy River and Salween River basins by its smooth snout. Garra tengchongensis can be further differentiated from congeners with a smooth snout in the Irrawaddy River and Salween River basins by the combination of the following characters: two pairs of barbels (vs. no barbels in G. nujiangensis); 12 circumpeduncular scales (vs. 16 in G. chakpiensis, G. nambulica, G. namyaensi, G. poecilura, G. spilota and G. ukhrulensis); 36–39 lateral scales (vs. 33–35 in G. abhoyai; 38–40 in G. chakpiensis; 34 in G. nambulica, and G. notata; 31 in G. namyaensi; 29 in G. poecilura; 30–31 in G. spilota; 40–41 in G. ukhrulensis).
Distribution. The species occurs in the Daying-jiang and Longchuan-jiang, both tributaries of the Irrawaddy River basin in west Yunnan, China.
Remark. The specimens from the Daying-jiang and Longchuan-jiang in west Yunnan were identified as G. kempi by Chu & Cui (1987, 1989). Zhang & Chen (2002) separated them from G. kempi and described a new species, G. tengchongensis. Garra tengchongensis can be distinguished from G. kempi by having the combination of the following characters: cylindrical anterior body (vs. depressed); a smaller mental adhesive disc, disc length 36.1–51.3% head length (vs. a large disc, disc length 42.9–50% head length) (Zhang & Chen 2002); a blunt snout (vs. broadly rounded); individuals smaller, adult standard length usually shorter than 10 cm and a few longer than 10 cm (vs. body larger, stand length in most adults longer than 10 cm).
