Scientists from Wildlife Institute of India discovered 13 new Raorchestes bush frog species across Northeast states (6 in Arunachal Pradesh, 3 Meghalaya), using genetics, acoustics, and morphology. The findings, from 2019-2024 surveys in 81 sites, raise India's bush frog count to 95, highlighting hidden biodiversity.
Discovery Details
Led by PhD scholar Bitupan Boruah with Dr. Abhijit Das (WII) and Dr. Deepak Veerappan (UK), the study spanned 2019-2024 across eight states, including 25 protected areas. Supported by National Geographic and Meghalaya Biodiversity Board, it examined 204 specimens and century-old museum samples.
Scientific Approach
An integrative taxonomy—mitochondrial DNA, nuclear genes, morphology, and bioacoustics—confirmed the species, resolving longstanding confusions. Seven found in protected areas like Namdapha Tiger Reserve; one in Nagaland's community forest. All endemic, boosting regional Raorchestes from 15 to 28 species.
