Chalcorana labialis, also known as the white-lipped frog, is a species of "true frog" in the family Ranidae.[1][2] As currently known, it is endemic to Peninsular Malaysia, although it might also occur in Singapore.[1] Molecular data suggest presence of three distinct lineages in the same area, one of which is not closely related to Chalcorana labialis and which could represent an unnamed species.[3]

Description edit
Adult males measure 37–48 mm (1.5–1.9 in) and adult females 44–71 mm (1.7–2.8 in) in snout–vent length.[2] The tympanum is distinct. The fingers have well-developed discs but no webbing. The toe discs are somewhat smaller; the toes have extensive webbing.[2][3] The dorsum varies from dark green to pale yellow, with or without brown spots on the back. The upper lip is creamy yellow or white. The ventral surfaces are cream-coloured. The hind limbs may have dark cross-bars.[2]

Chalcorana labialis occurs on vegetation by forest streams and swamps. It is common.[2] As of April 2019, this species has not been assessed for the IUCN Red List of Threatened Species.[4]
