A new species of filament barb has been described from the southern tip of India in the most recent issue of the Journal of Threatened Taxa.
Authors K Rema Devi, TJ Indra and JD Marcus Knight name the new barb Puntius rohani after Rohan Pethiyagoda for his work on Indian and Sri Lankan fishes.
It is distinguished from other filament barbs by the presence of a black club-shaped blotch the caudal peduncle, the absence of any other body colour pattern in front of the blotch, and the absence of black bands near the tip of the caudal-fin lobes.
