( Figs. 3E , 9 , 10A and 10B )

Garra orientalis : Chu & Cui 1987 (in part): 93–96 (Baoshan, Nu-jiang drainage; Wanding, Longchuan-jiang drainage; Mangshi [=Luxi], Mangshi-he; Yingjiang, Daying-jiang drainage); Chu & Cui 1989 (in part): 275–277 (Daojie, Nu-jiang drainage; Wanding, Longchuan-jiang drainage; (Mangshi [=Luxi], Mangshi-he; Nabang in Yingjiang, Irrawaddy River drainage; Chen 1998 (in part): 178–179 (Daojie in Baoshan, Nu-jiang drainage); Zhang et al. 2000 (in part): 239–241 (Yingjiang, Irrawaddy River drainage).

Garra salweenica Hora & Mukerji 1934 : 365–368 (Takaw, Kengtung State, Burma) [Salween River drainage]; Zhang & Chen 2002: 462 (Salween River basin); Zhang 2005 (in part): 14 (Liuku, Yunnan, China) [Nu-jiang drainage]; Chen 2013 (in part): 311 (Nu-jiang drainage and Nanting-he drainage, Yunnan, China).

Material examined. KIZ 2006000826 , 1 ex., 111.4 mm SL, Yunnan: Longling: Sanjiangkou, Nu-jiang (upper of the Salween River ) ; KIZ 2006011052 , 1 ex., 110.3 mm SL, Yunnan: Longyang (= Baoshan): Bawan, Nu-jiang ( upper Salween River ) ; SWFC 1510004 , 1 ex., 98.8 mm SL, Yunnan: Longling: Sanjiangkou, Nu-jiang ( upper Salween River ) ; SWFC 1510005–1510010 , 6 ex., 96.2–134.5 mm SL, Yunnan: Longyang (= Baoshan): Mangbang, Nu-jiang ( upper Salween River ) ; SWFC 1510019 , 1 ex., 86.0 mm SL; Yunnan: Lushui: Hongqiba, Nu-jiang ( upper Salween River ) .

Diagnosis. Meristic and morphometric data are shown in Tables 3 and 4. Garra salweenica can be easily distinguishted from its congeners without a proboscis in the Irrawaddy River and Salween River basins by having a well-developed transverse lobe and proboscis. It can be further distinguished from congeners with a transverse lobe and proboscis in the Irrawaddy River and Salween River basins by the combination of the following characters: the tri-lobed proboscis (vs. a unilobed proboscis in G. elongata , G. gotyla , G. gravelyi , G. litanensis , G. qiaojiensis , and G. rotundinasus ; the bi-lobed proboscis in G. bispinosa ); the tip of the upper caudal-fin lobe with a black blotch (vs. without a blotch in G. fuliginosa , G. qiaojiensis , G. rotundinasus , and G. surgifrons ; a black, longitudinal mark on median rays in G. elongata ); the proboscis slightly triangular in shape from the dorsal view, the middle lobe obviously projects forwardly (vs. proboscis quadrate in shape from the dorsal view, and middle lobe slightly protruding forward in G. surgifrons ), the transverse lobe and the proboscis with larger and denser tubercles (vs. the transverse lobe and the front area of the proboscis with smaller and fewer tubercles in G. surgifrons ); dorsal profile of body obviously curved (vs. profile almost straight in G. surgifrons ); 32–34 lateral scales (vs. 39–40 in G. elongata ; 34–35 in G. qiaojiensis ; 35–37 in G. rotundinasus ); 16 circumpeduncular scales (vs. 12 in G. qiaojiensis , G. litanensis , and G. rotundinasus ).

Distribution. Garra salweenica is only known from streams in the southern Shan States, Myanmar and Nujiang in Yunnan, China, all belonging to Salween River basin.
