A new species of nemacheilid loach, Aborichthys uniobarensis, is described from the Senkhi stream, upper Brahmaputra basin in Arunachal Pradesh, northeastern India. Aborichthys uniobarensis is distinguished from all congeners by the presence of 6–14 fused oblique bars along the dorso-lateral margin of the body, 21–28 oblique bars along the flank, vent closer to the snout tip than to the caudal fin base and caudal fin oval shaped with upper half more extended than lower.

Aborichthys uniobarensis sp. nov.
Diagnosis: Aborichthys uniobarensis is diagnosed from all congeners by the presence of 6–14 fused oblique bars along the dorso-lateral margin of the body (vs. rarely fused). Further, it chiefly differs from all congeners by the following combination of characters: 21–28 oblique bars on the body, dorsal and ventral adipose crests low, vent closer to the snout tip than to the caudal-fn base, caudal fin oval shaped with upper half more extended than lower, and comprised of two concentric black to light brown bars in male.
Etymology: The species name is from the Latin unio means ‘fuse or meet‘, and barensis refer to vertical oblique bars along the body, in allusion to most of the paired bars dorsally fused. A noun in apposition.
