Exostoma is a genus of sisorid catfishes native to Asia. These species are distributed in the Brahmaputra drainage of north-eastern India, and east and south to the Salween drainages in Burma. E. berdmorei is found in the Sittang and Salween drainages in Burma.[1] E. labiatum is known from the Brahmaputra drainage in north-eastern India, but has also been recorded in the Salween drainage in Burma, the Ayeyarwady drainage in China, and the Brahmaputra drainage in Tibet and Burma.[1][2] E. stuarti is from the Ayeyarwady River of Burma and India; however, it has not been collected since its original discovery.[1][3] E. labiatum is found in mountain rapids.[2]

In a 2007 checklist of sisorid and erethistid catfishes, Thomson lists E. stuarti and E. vinciguerrae as valid species.[1] In a 2007 checklist of catfishes, Ferraris lists these two species as species inquerendae, noting that these species are either treated as valid or as synonyms of E. labiatum.[4]
