Hyla annectans

The following description is taken from George Albert Boulenger's Fauna of British India, including Ceylon and Burma:[5]

The tongue circular, slightly nicked, and free behind. Vomerine teeth in two groups on a level with the hinder edge of the choanae. The head broader than long; snout short, rounded; canthus rostralis distinct; interorbital space as broad as the upper eyelid; tympanum distinct, about half the diameter of the eye. Fingers webbed at the base; the toes two-thirds webbed; disks are well developed. The tibiotarsal articulation reaches the tympanum or the eye. Skin smooth above, granular beneath; a strong tuberculated fold from the eye to the shoulder. Green above; 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; sides of thighs with deep black spots on a bright yellow ground; two outer fingers and two outer toes green; beneath whitish, immaculate. Male with an external subgular vocal sac and black nuptial excrescences on the thumb.

From snout to vent 2 inches (5.1 cm).

Modern sources give snout–vent length 28–39 mm (1.1–1.5 in) for males and 32–45 mm (1.3–1.8 in) for females.[3]

Hyla annectans occurs in tropical evergreen and deciduous forest at elevations of 600–2,500 m (2,000–8,200 ft) above sea level,[1] down to 100 m (330 ft) in India.[4] It can also be found in grasslands and agricultural land close to forests. It is largely arboreal. Breeding is explosive and takes place in ponds and terraced paddy fields.[1]

It is common in parts of its range, notably China. It can be threatened by habitat degradation, including water pollution. It is collected for in India. The range of this species includes many protected areas.[1]
