Binomial name: Hyla annectans, Thomas Caverhill Jerdon, 1870
Jerdon's tree frog (Hyla annectans) is a species of tree frog found in southwestern and central China, northeast India (Assam, Meghalaya, Mizoram, Arunachal Pradesh and Nagaland), northern Myanmar, extreme northern Thailand, and Viet Nam. It probably occurs more widely than current records suggest in Southeast Asia, especially in areas between known sites. It is known from elevations between 600 and 2500 m above sea level.
The tongue is circular, slightly nicked, and free behind. Vomerine teeth are in two groups on a level with the hind edge of the choanae. The head is broader than long, with a short, rounded snout; the canthus rostralis is distinct, and the interorbital space is as broad as the upper eyelid. Thetympanum is distinct, about half the diameter of the eye. The fingers are webbed at the base, the toes are two-thirds webbed, and the disks are well developed. The tibiotarsal articulation reaches the tympanum or the eye. The skin is smooth above, and granular beneath; a strong tuberculated fold runs from the eye to the shoulder. In color, the species is green above, with a dark, lateral streak, light-edged above, ending in two or three deep black spots, separated or confluent on the groin, which is bright yellow. The sides of thighs have deep-black spots on a bright-yellow ground color; the two outer fingers and two outer toes are green, and beneath is whitish and immaculate. The male has an external subgular vocal sac and black nuptial excrescences on the thumb.
From snout to vent, this frog is 5.1 cm long.
Its distribution includes the Khasi Hills, and Kakhyen Hills, Upper Burma.
The species was thought to have been extinct since 1870, but was later rediscovered after a three-year search that began in 2007.
