Abstract


During the malacological survey in the Dalma Wildlife Sanctuary and different regions of Saranda forests of Deccan peninsula in Jharkhand, an unusual Florida’s native freshwater mollusc Seminole Rams-Horn, Planorbella duryi from South Karo River was encountered. Earlier, this non-indigenous species was reported from the Godavari River in the Nasik district of Maharashtra state of India although there was confusion on the presence of Planorbella scalaries and Planorbella duryi. Occurrence of P. duryi, has been confirmed along with distribution, ecology, and probable dispersal hypothesis has been discussed.
