Xanthophryne koynayensis (common names: Humbali Village toad, chrome-yellow toad, Koyna toad) is a species of toad in the Bufonidae family. It is endemic to the Western Ghats of India where it is known from Koyna (including Koyna Wildlife Sanctuary[1]), Maharashtra.[2] Formerly included in the genus Bufo it has been since made the type species for the genus Xanthophryne and is a sister species of Xanthophryne tigerina.[3]

Xanthophryne koynayensis are relatively small toads: adult males measure 24–32 mm (0.94–1.26 in) in snout–vent length.[3]

Xanthophryne koynayensis is a rare species. Its natural habitats are moist to wet evergreen forest and dry riparian grassland. It is threatened by habitat loss caused by agriculture and clear cutting of forests.[1]
