About Kurixalus berylliniris Wu, Huang, Tsai, Li, Jhang & Wu, 2016
Adult male Kurixalus berylliniris measure 29–42 mm (1.1–1.7 in) in snout–vent length, while adult females measure 28–46 mm (1.1–1.8 in). The species has a moderately slender, somewhat flattened overall body shape. Its head is wider than it is long. The tip of the snout is pointed, and the snout appears obtuse when viewed from the side. The canthus rostralis is curved and prominent. The tympanum is distinct, measuring about half the diameter of the eye, and a supratympanic fold is present. The limbs are slender. The tips of the fingers and toes are expanded into discs. The fingers have slight webbing, while the toes are approximately half-webbed. Dorsal skin is granular and covered in small tubercles. This species has two distinct color morphs: dark and light. The dark morph ranges from dark green to deep tan, marked with a black X-shaped blotch alongside other irregular blotches; its tympanum is light yellowish-brown with small dark spots. The light morph is light emerald green, and its dorsal X-shaped pattern is obscured. The venter is cream-colored, with tiny black spots scattered across the gular region. The iris ranges from emerald to light green. This species is found in eastern Taiwan, south of central Hualien. It occurs on the eastern slopes of the Central Mountain Range and in the Coastal Mountain Range. Kurixalus berylliniris has been recorded in moist broad-leaf forests and forest edges, at elevations between 225 and 1,250 m (738–4,101 ft) above sea level. It is an arboreal species. Its eggs and tadpoles have been found in small water pools contained in decaying trunks of the tree fern Cyathea spinulosa. The tadpoles of this species are oophagous. Specific threats to Kurixalus berylliniris have not been confirmed. While deforestation has generally slowed in Taiwan, loss of the tree holes that the species uses for breeding is a potential threat. This species is not known to occur in any protected area.
