Ingerophrynus is a genus of true toads with eleven species. Ten of the species in this genus used to be thought to be species of the genus "Bufo". In 2007 a new species, "Ingerophrynus gollum", was added to this genus. This species is named after the character Gollum created by J. R. R. Tolkien. These species live in Southern Yunnan and Indochina; peninsular Thailand and Malaya to Sumatra, Borneo, Java, Nias Island, and Sulawesi.
