Researchers from the Zoological Survey of India and the Andhra Pradesh Biodiversity Board have rediscovered the Sri Lankan golden-backed frog (Hylarana gracilis) in the Koundinya wildlife sanctuary, Andhra Pradesh, marking its first sighting in India in two centuries. This discovery increases India’s freshwater frog species count to 20. Bharath Bhupathi and his team identified the species using morphological and DNA barcoding tools. The rediscovery underscores historic land bridges between India and Sri Lanka, with genetic analysis indicating minimal divergence between populations.
