目的 调查和了解西藏自治区（西藏）的蚊类区系。方法 2017年8-9月对藏东南地区各类型孳生地的蚊幼虫进行调查取样。结果 首次在西藏发现巨蚊属（Toxorhynchites）、尤蚊属（Udaya）和直脚蚊属（Orthopodomyia）3属及紫腹巨蚊（T.gravely）、银尾尤蚊（U.argyrurus）和拟按直脚蚊（O.anopheloides）3个物种，均为西藏地区蚊类属和种新纪录。该文将这3属及种的主要形态特征、分布区、孳生环境及其以实物作为凭证标本绘制的雄蚊尾器结构图等内容分别进行了记述和报道。结论 由于藏东南地区海拔相对较低、雨量充沛和气候环境复杂多样，蚊类属及种类都较为丰富。随着区系调查的深入，蚊类属和种的丰富度无疑还会进一步增加。

Objective To investigate and understand the fauna of mosquitoes in Tibet autonomous region. Methods Mosquito larvae of various breeding habitats in southeastern Tibet were investigated and sampled. Results Genus Toxorhynchites, Udaya, and Orthopodomyia, and species Toxorhynchites gravely, Udaya argyrurus, and Orthopodomyia pheloides were first found in Tibet. They are all new records of mosquitoes in Tibet. In this paper, the main morphological characteristics, distribution area, breeding environment of the three genera and species, and the morphology of male genitalia with the physical specimens are described and reported. Conclusion Due to the relatively low altitude, abundant rainfall and complex climate and environment in southeastern Tibet, mosquitoes are abundant. With the further investigation of the fauna, the genus and species richness of mosquitoes will undoubtedly increase further.
