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.
六个核基因的分子变异为一个新的鲤形目科，即鱚科的确认提供了实质性的系统发育证据，该科包括神秘的南亚泥鳅属 Ellopostoma。目前的六个泥鳅科形成一个单系群，Nemacheilidae 是鱚科的姐妹群；而 Vaillantellidae 则是除了鮡科以外的所有科的姐妹群。虽然 Cobitoidea 超科包括八个科，但尽管进行了广泛的分子分析，这个鲤形目内的大型分支的单系性仍然是一个令人困扰的问题，需要进一步研究。
