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 首次在西藏地区发现和捕获领蚊属（Heizmannia）的异刺领蚊（Hz.heterospina）、多栉领蚊（Hz.reidi）和线喙领蚊（Hz.macdonaldi）3个蚊种，均为当地的蚊属和种新纪录。将该蚊属及种的主要形态特征、分布区、孳生环境及其雄蚊尾器结构图等分别进行记述和报道。结论 领蚊属是典型的东洋区类群，藏东南首次发现该蚊属及种有分布，提示藏东南海拔较低的地区蚊类主要属于东洋区系。此外，该蚊属和种的发现，也显示了藏东南地区蚊类多样性较高的特征。

Objective To investigate the fauna of mosquitoes in Tibet Autonomous Region, China. Methods From August to September, 2017, investigation and sampling were performed for mosquito larvae in various types of breeding sites in southeastern Tibet. Results The genus of Heizmannia and three mosquito species of Hz. heterospina, Hz. reidi, and Hz. macdonaldi were found and captured for the first time in Tibet. They were the new records of the genera and species of local mosquitoes. This article described and reported the main morphological characteristics, distribution areas, breeding environment, and the structure diagram of male terminalia of the genus and species. Conclusion Heizmannia belongs to the Oriental fauna. The distribution of this genus and related species was found for the first time in southeastern Tibet, suggesting that the mosquitoes in southeastern Tibet with a low altitude belong to the Oriental fauna. In addition, the discovery of this genus and related species shows high diversity of mosquitoes in southeastern Tibet.
