Tariqilabeo kaladanensis, a new species of fish (Teleostei: Cypriniformes) from the Kaladan basin of Mizoram, northeast India.

A new labeonin fish, Tariqilabeo kaladanensis, is described from the Kaladan River of Mizoram, northeast India. The new species is distinguished from its congeners by having combination of the following characteristics: frenum of rostral cap exposed, folded and continuous with the subtoral fold, frenum of upper lip covered by the rostral cap, presence of dark humeral spot covering 4th and 5th lateral-line scales extending to scales immediately above and below lateral-line scales, 32-34 lateral-line scales, lacking mid-lateral stripe on the flank and possessing 28-29 gill rakers on the first-gill arch. The morphological distinction of the new species is well supported by the mitochondrial gene data with a wide genetic distance of 4.1%-12.7% (coi) and 7.2%-15.6% (cytb) from all other congeners.
