摘要
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幼蚊进行调查取样、标本制作和分类鉴定。结果在林芝市墨脱县采获1批伊蚊属(Aedes)标本,经鉴定其中发现伊蚊属双角蚊亚属(Subgenus Diceromyia)的沃氏伊蚊〔Aedes(Diceromyia)whartoni Mattingly,1965〕,该亚属和物种首次在我国西藏自治区和云南省发现,为我国蚊亚属和物种新纪录。该文中将双角蚊亚属及物种的主要形态特征、地理分布区、孳生环境及其雄蚊尾器结构图等内容分别进行了简述和报道。结论迄今,西藏已知伊蚊属共16种。
Objective To investigate the fauna of mosquitoes in Tibet Autonomous Region, China. Methods From August to September, 2017, investigation and sampling, specimen preparation, and taxonomic identification were performed for mosquito larvae in various types of breeding sites in southeastern Tibet. Results A batch of specimens of the genus Aedes were collected in Motuo county, Linzhi. Among them, Aedes(Diceromyia) whartoni Mattingly, 1965 was identified.The subgenus and species, which were first found in Tibet Autonomous Region and Yunnan province, were a new record of subgenus and species in China. This article briefly describes and reports the main morphological characteristics,geographical distribution, breeding environment, and male terminalia structure of the subgenus Diceromyia and the species whartoni of Aedes. Conclusion Up to now, 16 species of Aedes are known in Tibet.
