根据成虫标本、骨骼标本、蝌蚪和卵的21个形态特征，重建了Oreolalax属17种的系统发育。确定了4个种组，其中最原始的是普通野生稻种组，其次是魏戈尔迪野生稻种组，其次是亚洲野生稻种组，第三是亚洲野生稻种组，而最新的多样性种组是平江野生稻种组。根据系统发育树上形态特征的进化趋势，提出鼓室、鼓环、小柱、勺状软骨和趾间网状结构的演化反映了从水生到陆生的习性变化。因此，Oreolalax被认为是进一步研究从水生到陆地的形态特征演化的重要代表属。(C)2009年中国和中国科学院国家自然科学基金。爱思唯尔有限公司出版，《科学》中国出版社出版。版权所有。
A phylogeny of 17 species in the genus Oreolalax is reconstructed based on 21 morphological characters from adult specimens, skeleton specimens, tadpoles and eggs. Four species groups are recognized, of which the O. rugosus species group is the most primitive, the O. weigoldi species group is the second, the O. omeimontis species group is the third and the O. pingii species group is the most recently diversified. Based on the evolutional tendency of the morphological characters on the phylogenetic tree, it is proposed that the evolution of tympanum, tympanic annulus, columella, spoon-like cartilage and the web between toes reflect the habit changes from aquatic to terrestrial. Thus, Oreolalax is regarded as one important representative genus to study further the evolution of morphological characters from aquatic to terrestrial.
