Chalcorana macrops

Chalcorana macrops grows to at least 45 mm (1.8 in) in snout–vent length. The eyes are very large. The head is rather large with a rounded snout. The tympanum is distinct. The fingers are rather and long slender and have well-developed discs. The toes are two-thirds webbed and have discs that are somewhat smaller than the finger discs. Skin is smooth or with a few small warts dorsally. Dorsal colouration is olive-brown. The sides are greyish and marbled with dark brown. Males have an internal vocal sac.[3][4]

Chalcorana macrops occurs along canopy-covered streams—its presumed breeding habitat—in primary and secondary lowland forests at elevations of 300–1,000 m (980–3,280 ft) above sea level. It is threatened by habitat loss caused by smallholder farming. Also water pollution from agriculture is a threat. Some of its habitat is protected by the Lore Lindu National Park.[1]
