Abstract: The morphological variation of Gansu zokors (Myospalax cansus)was studied from morphological data from five geographical populations. The results indicated that 34 morphological variables are significantly different among these populations.The comparison of female and male morphological variables showed that 30 variables are significantly different,so Gansu zokors have characteristics of sexual dimorphism,and different analyses should be made among males or females respectively. Q-cluster analysis uncovered that,for males,the Lintao population and the Ledu population are most similar, the Zhenyuan population and the Fuxian population are most similar,and Guyuan population is closer to the Zhenyuan and Fuxian populations. For females,the same results occur,but the Guyuan population is closer to the Lintao and the Ledu populations. Based on the synthetic analysis from morphologics,Gansu zokors should be divided into 3 geographical taxa: a Lintao-Ledu unit,a Guyuan unit and a Zhenyuan-Fuxian unit.
Key words: Gansu zokors (Myospalax cansus), Geographical population, Morphological variation, Q-cluster analysis, Sexual dimorphism
