Abstract: Objective To investigate the fauna and distribution of fleas in the southeast of Tibet autonomous region, and to provide a basis for further research on flea fauna in the region. Methods Linzhi in the southeast of Tibet was taken as the area for research, and the small mammals and their parasitic fleas in the farming areas of different altitudes were taken as the study subjects; the small mammals were captured using large-size mouse traps and their parasitic fleas were investigated and sampled, and the obtained specimens were classified and identified in the laboratory. Results From the specimens of the genus Genoneopsylla Wu, Wu et Liu, 1966, female specimens of G.zhiyini Wu, Ge et Lan, 2003 were identified for the first time. The morphology and characteristics of the female flea species were described in this article. Conclusion Up to now, four species of the genus Genoneopsylla distributed in Tibet have been identified. With increasing investigation and taxonomic study of the fleas, the number of species of the genus will become larger.

摘要： 目的 调查和了解西藏自治区（西藏）东南部蚤类区系与分布的状况，为进一步开展该地区蚤类区系的研究奠定基础。方法 以藏东南林芝市为调查研究的空间范围，不同海拔高度农耕区的小型兽类及其寄生蚤作为研究对象，应用大号鼠夹捕获小型兽类并对其体表寄生蚤进行调查取样，所获标本在实验室分类和鉴定。结果 在所获继新蚤属（Genoneopsylla Wu，Wu et Liu，1966）标本中，首次发现了支英继新蚤（G.zhiyini Wu，Ge et Lan，2003）的雌性标本。该文将此蚤种雌性的形态和特征进行了记述。结论 迄今，西藏已知分布的继新蚤属共4种。随着蚤类调查及分类研究的深入，该属的种类还会进一步增加。
