Objective To investigate the species composition and geographic distribution of fleas on plateau zokors (Eospalax baileyi) and consequently to clarify the fauna of zokor fleas in the Qinghai-Tibet Plateau, China. Methods Ground arrows were used to kill E. baileyi, and all fleas on the zokors were collected by combing and were then identified in the laboratory and analyzed statistically. Results A total of 282 E. baileyi were captured from 18 sampling sites, and 203 (71.99%) of them were infected by one or more fleas. A total of 835 fleas were collected, with a total flea index of 2.96 individuals per host. The hierarchical cluster analysis grouped the 18 sites into 3 main clades. Clade A was dominated by Neopsylla paranoma; clade B was dominated by N. sellaris; clade C had the fewest flea individuals. Conclusion The area around the Qinghai Lake is dominated by N. paranoma, the southeastern area of Qinghai province is a unique region for N. sellaris, and the Yellow River seems to have little influence on the fauna of fleas on E. baileyi.
