Hyla annectans is a species of tree frog in the family Hylidae. It is found in Asia south of the Himalayas in northeast India (Assam, Nagaland, Manipur, and Meghalaya), northern Myanmar, and northern montane Vietnam and southwestern and central China (Yunnan, Guizhou, Sichuan, Hunan). There are isolated records in northwestern Thailand and adjacent Myanmar. There is uncertainty whether Hyla gongshanensis from China should be recognized as a distinct species. This widespread species has many common names: Jerdon's tree frog, Assam treefrog, Indian hylid frog, green leave frog, or Southwestern China treefrog.
