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
).
