中国库蠓属带纹亚属地理分布及一中国新纪录种(双翅目:蠓科)

Geographical distribution of Culicoides(Beltranmyia)(Diptera:Ceratopogonidae)and a new record species in China

目的调查、整理我国库蠓属带纹亚属的地理分布。方法于2010-2020年在中国10省(自治区)29市、县(区)的林区、居住区、牛舍、羊舍、鸡舍、猪舍,采用人帐诱、诱虫灯诱和挥网采集蠓标本,同时收集相关文献,利用Excel 2010软件对数据进行整理和分析。结果共采获库蠓属带纹亚属19种,结合文献,中国库蠓属带纹亚属现知有39种,共分布在中国27省(自治区、直辖市)135市、县、区,其中环斑库蠓分布在27省(自治区、直辖市)91市、县、区。区系分布研究结果表明,古北界分布29种,东洋界分布16种,2界共有分布6种;带纹亚属在中国动物地理区划东北区分布有20种、华北区8种、蒙新区8种、青藏区5种、西南区6种、华中区11种和华南区5种。描述了中国一新纪录种,同色库蠓[Culicoides(Beltranmiya)homochrous Remm,1968(雄虫)]。观察标本保存在北部战区疾病预防控制中心(沈阳110034)。结论中国库蠓属带纹亚属包括39种,分布在中国27省(自治区、直辖市)135市、县、区;环斑库蠓在我国古北界和东洋界的7个动物地理区均有分布,为中国广布种。

Objective To investigate and research the geographical distribution of Culicoides(Beltranmyia)in China.Methods From 2010 to 2020,midges were captured with human-baited net traps,light traps,and insect nets in the woods,residential areas,cattle pens,sheepfolds,chicken houses,and pigpens in 29 counties/cities in 10 provinces/autonomous regions of China.Relevant literature was reviewed.Excel 2010 software was used for data analysis.Results A total of 19 species of Culicoides(Beltranmyia)were captured in this study.Based on literature review,there are a total of 39 known species under subgenus Beltranmyia.They are distributed in 135 counties/cities in 27 provinces/autonomous regions of China,and C.circumscriptus is distributed in 91 counties/cities of 27 provinces/autonomous regions.According to fauna distribution,29 species are in the Palaearctic realm,16 species in the Oriental realm,and 6 species in both the Palaearctic and Oriental realms.The zoogeographic distribution of Beltranmyia in China is 20 species in Northeastern region,8 in North China,8 in Mongolia-Xinjiang,5 in Qinghai-Tibet,6 in Southwest region,11 in Central China and 5 in South China.A new record species in China was reported:C.(B.)homochrous Remm,1968(♂).Conclusion There are 39 known species under Culicoides(Beltranmyia)in China,which are distributed in 135 counties/cities of 27 provinces/autonomous regions.Culicoides circumscriptus is a widely distributed midge species in China that is present in the seven regions of both Palaearctic and Oriental realms.The specimen is deposited in the Center for Disease Control and Prevention of Northern Theater Command(Shenyang 110034).
