Beduka koynayensis (common names: Humbali Village toad, chrome-yellow toad, Koyna toad) is a species of toad in the family Bufonidae. It is endemic to the Western Ghats of India where it is known from Koyna (including Koyna Wildlife Sanctuary[1]) in the Maharashtra state.[2] Formerly included in the genus Bufo and Xanthophryne, it is currently the type species of genus Beduka.[4]
History
Beduka koynayensis has been described twice using the same materials[5] collected in connection with the Koyna Hydroelectric Project:[3] first as Bufo koynayensis by Soman in 1963, and then as Bufo sulphureus by Grandison and Daniel in 1964.[5]
Description
Beduka koynayensis are relatively small toads: adult males measure 24–32 mm (0.94–1.26 in) in snout–vent length.[5] The body is covered by small warts with black tips and dark brown in colour; there are yellow patches on the flanks, thighs, and shoulders. The tympanum is indistinct.[3]
Habitat and conservation
Beduka 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]
