Discherodontus , a new genus of cyprinid fishes from southeastern Asia

Three species of southeast Asian barbins were found to have two rows of pharyngeal teeth, a character unique among barbins. These species also share several other characters which indicate their close relationship, and allow the taxonomic recognition of the genus. Members of this new genus, Discherodontus , are found in the Mekong, Chao Phrya, and Meklong basins of Thailand and the Pahang basin of the Malay peninsula. The new genus appears to be most closely related to Chagunius of Burma and India, and a group of at least six genera of the southeast Asia-Sunda Shelf basins.
