最近的分子生物学研究表明，该属是从啮齿动物亚科仓鼠（Cricetinae）进化而来。利用线粒体12 S rRNA和细胞色素B基因的全序列对这一结论进行了验证。根据我们的分析，Myospalax似乎是一个包含Spalacinae和Rhizomyinae亚科的分支的姐妹，所有这三个谱系似乎都是Muroidea总科的基础。基于这三个谱系的位置，我们建议，他们被放置在一个不同的家庭，Spalacidae，而不是归入家庭Muridae的亚科。最后，我们的分析表明，Myospalax的早期位置作为一个成员的仓鼠是一个单一的错误识别的标本，这是不是Myospalax的结果。(C)2003年爱思唯尔公司All rights reserved.
Recent molecular studies have concluded that the genus Myospalax evolved from within the rodent subfamily Cricetinae. This conclusion was tested using the complete sequences from the mitochondrial 12S rRNA and cytochrome b genes. Based on our analyses, Myospalax appears to be sister to a clade containing the subfamilies Spalacinae and Rhizomyinae, and all three of these lineages appear to be basal to the superfamily Muroidea. Based on the position of these three lineages, we suggest that they be placed in a distinct family, the Spalacidae, rather than subsumed as subfamilies in the family Muridae. Finally, our analyses suggest that the earlier placement of Myospalax as a member of the Cricetinae is the result of a single misidentified specimen, which was not a Myospalax. (C) 2003 Elsevier Inc.
