Garra birostris Nebeshwar & Vishwanath, 2014

( Fig. 6 )

Garra birostris Nebeshwar & Vishwanath 2014: 104 , fig. 5. Type locality: Dikrong River and Doimukh, Papum Pare district, Arunachal Pradesh, India. Holotype: MUMF 4302 .

Material examined. 1 Specimen, 88.7 mm SL, CNR 13037; Bhutan: Samdrup Jongkhar: Tikrikhola, D.B. Gurung & R.J. Thoni, October 20, 2013.

Remarks. This species was encountered in a stream in southeastern Bhutan. It was identified by its prominent bi-lobed proboscis, tubercle pattern on the rostral lobe and depressed rostral surface, caudal-fin pigmentation, and overall body shape. There is a slight difference in snout shape when viewed ventrally compared to Nebeshwar & Vishwanath’s specimen, however, based on only one specimen, we cannot definitively separate it from G. birostris . It was collected in close proximity to localities in Arunachal Pradesh where Nebeshwar & Vishwanath collected G. birostris . It is possible that this species, and others described by Nebeshwar & Vishwanath (2014), have already been described by early ichthyologists who’s descriptions remain vague, and without holotypes. We therefore gave priority to those species names available with ample and precise diagnostic traits.
