Molecular variation in six nuclear genes provides substantive phylogenetic evidence for the recognition of a new cypriniform family, the Ellopostomatidae, to include the enigmatic Southern Asia loach genus Ellopostoma . The current six loach families form a monophyletic group, with the Nemacheilidae as the sister group to Ellopostomatidae; Vaillantellidae forms the sister group to all families exclusive of Botiidae. While the superfamily Cobitoidea includes eight families, the monophyly of this large clade within the Cypriniformes remains a vexing problem despite extensive molecular analyses and is in need of further investigation.
