Identification:
This tree frog species is small, with males smaller than females. Male snout-vent length ranges from 21.4 to 24.5 mm, while females measure 26.8 to 27.3 mm. The skin is pale green. The rear of the forelimbs, the front of the thighs, and the groin are dull yellow. Black spots are present on the flanks, belly, and thighs. The snout is pointed and triangular. The head length is equal to the head width, and the tibia is visible.
The nostrils protrude slightly and are oval-shaped, positioned closer to the mouth than the eyes. The tympanum diameter is approximately one-third the diameter of the eye. The tympanum is elevated above the surrounding skin. The legs are long. The toe pads on both forelimbs and hind limbs are relatively large, and the hind limb webbing is short. The vocal sac is well-developed, producing various sound types.
Biology and Ecology:
This species typically forages after rain and is found on tree leaves in evergreen forests at an altitude of 800–1000 m.
This new tree frog species was named after Professor Hoàng Xuân Quang, a herpetologist from Vinh University of Education.
