Olyra astrifera, a new species of Olyrid catfish is described from the Manimalai River of south Kerala in southern Western Ghats. It can be distinguished from its congeners (except O. horae) by its adipose fin confluent of with caudal base, pectoral fins with weak serrations and strong dentitions, a greater length of the adipose fin base, a shorter distance of dorsal fin origin to origin of adipose fin and pores of the lateral line canal. It is further distinguished from O. horae by the number of anal fin rays (15 vs. 21) and the upper lobe of the caudal fin greater than one half longer than lower lobe (vs.slightly longer than lower). A neotype of Olyra longicaudata McClelland 1842 is designated from specimens collected from north-eastern India. Presence of Olyra astrifera from peninsular India is a record of the representation of the subfamily Olyrinae.
