Gracixalus patkaiensis, Alcalus fontinalis and Nidirana noadihing: In Arunachal Pradesh’s Namdapha-Kamlang protected area network along the Myanmar border, scientists discovered 3 new frog species belonging to new genera, including Gracixalus patkaiensis, Alcalus fontinalis and Nidirana noadihing. According to the lead researcher Abhijit Das of the Wildlife Institute of India, “Our initial observations show a dominant influence of southeast Asian faunal elements in the lower elevations and largely Himalayan ones in the upper reaches. However, more surveys are needed to ascertain these faunal boundaries,” he said. Namdapha region, located on the border, faces many anthropogenic pressures that pose conservation challenges,.The discoveries bring India’s amphibian species count to around 470.
