Identification:
This small tree frog species has a head-body length of approximately 27-38 mm. It lacks vomerine teeth (teeth on the roof of the mouth). The snout is relatively long and rounded anteriorly. There are no skin tubercles on the eyelids or heel. The skin is smooth, lacking serrated skin fringes along the arms and legs. The dorsal surface (head and body) is gray-green or moss-colored, featuring a brown Y-shaped mark on the back. The dorsal surfaces of the limbs exhibit dark transverse stripes. The throat and belly are cream-colored, with small, dark speckles.
Biology and Ecology:
This species is arboreal (tree-dwelling) and appears only during the rainy season in the limestone mountains of eastern Cao Bang province, at elevations of 400-650 meters above sea level. Notably, this tree frog does not inhabit streamsides but rather resides in limestone valleys or cave entrances, relatively far from water sources. The species name is dedicated to the World Association of Zoos and Aquariums (WAZA) in recognition of their contributions to the conservation of wildlife, including amphibians.
Distribution:
The species has been newly discovered in the limestone mountains of eastern Cao Bang province.
