应用聚类分析探讨我国原Metaredlichioides Chien and Yao,1974属中13个种和产于哈萨克斯坦的Ushbaspis属的模式种——Ushbaspis granulata Pokrovskaya,1965的分类。将我国原Metaredlichioides属中13个种归并和修订为4个种:Ushbaspis constricta(Chien and Yao),U.hubeiensis(Lin),U.meiziwanensis(Yin)和U.shiqianensis(Yin)。并对Metaredlichioides与Ushbaspis两个属的模式种进行定量分析,所取得的结论与张文堂(Chang et al.,1997)以定性分析提出Metaredlichioides是Ushbaspis的晚出异名的意见完全一致。 Cluster analysis was used to study the taxonomy of 13 species in the genus Metaredlichioides Chien and Yao of China, and the genus Ushbaspis in Kazakhstan, Ushbaspis granulata Pokrovskaya, 1965. Thirteen species of the genus Metaredlichioides in our country were merged and revised into four species: Ushbaspis constricta (Chien and Yao), U.hubeiensis (Lin), U. meiziwanensis (Yin) and U.shiqianensis (Yin). And the quantitative analysis of the genus Metaredlichioides and Ushbaspis is consistent with the suggestion made by Zhang et al. (1997) that qualitative analysis of Metaredlichioides is the late out of Ushbaspis.
