Remarks.
When live, this species is most easily diagnosed by coloration characters, appearing bright orange or red on the lips, and the anterior edge the dorsal, anal, and paired fins, as well as on the upper and lower caudalfin margin. Significant diagnostic traits on preserved specimens include an anteriorly placed vent, separate anterolateral lobe, medial caudal-fin stripe, submarginal stripe on the dorsal fin, and seven branched dorsal-fin rays. A weakly developed transverse groove and proboscis with few tubercles is similar to that of
G. gotyla
but is less pronounced in
G. a r u p i
.
This species was collected primarily in central
Bhutan
, in tributaries of the Punatsangchhu and Laringkhola rivers. They are found in mid-elevation streams typically above
200 m
and below
1000 m
. They tend to be found in runs, riffles, and torrents, with few encounters in pools, with the exception of larvae and juveniles, which prefer the gravel substrate of pools. They were frequently sampled in sympatry with
Barilius
,
Neolissochilus
,
Psilorhynchus
,
and
Schistura
.
