摘要: 目的 调查西藏自治区错那县蠓的种类分布。方法 采用诱虫灯诱法在牛舍和居住区采集蠓标本,用树胶酚封片法制作玻片标本。结果 描述了发现于西藏自治区错那县的纽结阿蠓(Alluaudomyia desma Yu,2005)雄虫。鉴别特征:两复眼的小眼面间有柔毛,翅径中横脉和径2室端部各有1个暗斑,尾器第9背板后缘中部有1对角突,阳茎中叶端部呈1对指状突,阳基侧突细杆状,基部有2对钩状弯曲,端部近侧弯曲。纽结阿蠓雄虫的翅斑与龙州阿蠓(All.longzhouensis Hao et Yu,1991)相近似,但后者雄虫尾器阳茎中叶和阳基侧突的形状与纽结阿蠓雄虫明显不同。观察标本1,保存于北部战区疾病预防控制中心(沈阳110034)。结论 新发现雄虫标本特征与原描述雌虫模式标本一致。结合形态特征、采集地点和时间,鉴定为纽结阿蠓,补充了原定种所缺乏的重要的雄虫信息,为该蠓种的分类鉴定提供了依据。

Abstract: Objective To investigate the species distribution of midges in Cona county, Tibet Autonomous Region, China. Methods Midges were captured with light traps in cattle pens and residential areas in Cona county, followed by slide specimen preparation with phenol balsam. Results We described a male midge of Alluaudomyia desma Yu, 2005 found in Cona county. The identifying characteristics are:Eyes with interfacetal hairs. Wing with a dark spot in r-m cross-vein,and with a dark spot in distal portion of R2 cell. Genitalia ninthtergum apically with two angular process, adeagus with two digitate process in distal portion, parameres with rod-shaped, basal portiot with two hookted bend,and end with lateral curvature. The wing pattern of male All. desma is similar to that of All. longzhouensis Hao et Yu, 1991, but the latter male insect has distinct aedeagus and paramere appearances from male All. desma. The specimen is deposited in the Center for Disease Control and Prevention of Northern Theater Command (Shenyang, 110034). Conclusion The characteristics of the newly found male specimen, which are consistent with the original description of the female holotype specimen. Combined with morphological characteristics, collection location and time, it was identified as All. desma, which supplement important male information that was lacking in the original species, and provides a reference for the classification and identification of All. desma.
