Chalcorana macrops is a species of "true frog" in the family Ranidae. It is endemic to Sulawesi, Indonesia.[1][3] Common name Masarang frog has been coined for it.[3] The specific name macrops refers to the large eyes of this frog.[2][4]
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.[2][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]
