Abstract

To help resolve the systematic position of Myospalacine (zokors) and to clarify the phylogenetic relationships among zokor species, complete mitochondrial 12S rRNA and cytochrome b gene sequences were determined for seven zokor species from China. Phylogenetic relationships among all extant zokors, except the Siberian zokor (Myospalax myospalax) and Smith's zokor (Eospalax smithi), were reconstructed with the Chinese bamboo rat (Rhizomys sinensis) as an outgroup. Our results support the generic status of Eospalax and also support the validity of the specific status of Eospalax cansus, Eospalax baileyi and Eospalax rufescens.

摘要

为了帮助确定鼢鼠亚科（鼢鼠）的系统位置，并阐明鼢鼠物种之间的系统发育关系，我们测定了来自中国的7种鼢鼠的完整线粒体12S rRNA和细胞色素b基因序列。以中华竹鼠（Rhizomys sinensis）为外类群，重建了除中华鼢鼠（Myospalax myospalax）和斯氏鼢鼠（Eospalax smithi）之外的所有现存鼢鼠之间的系统发育关系。我们的结果支持甘肃鼢鼠属（Eospalax）的属级地位，也支持甘肃鼢鼠（Eospalax cansus）、贝氏鼢鼠（Eospalax baileyi）和罗氏鼢鼠（Eospalax rufescens）的种级地位的有效性。
