中国库蠓属吉林亚属的分类及一新种(双翅目:蠓科)

Classification of Culicoides (Jilinocoides) and a new speciesfrom China(Diptera:Ceratopogonidea)

目的调查整理中国库蠓属吉林亚属的种类分布和分类。方法2022年在黑龙江省逊克县的猪舍、牛舍用诱虫灯采集吸血蠓,制作玻片标本进行分类鉴定;收集相关文献。结果共采获10000只吸血蠓类,经分类鉴定包括12种库蠓,其中发现了库蠓属(Culicoides)吉林亚属(Jilinocoides)一新种—类敦化库蠓Culicoides(Jilinocoides)subdunhuaensis sp.nov.。该新种与敦化库蠓Culicoides(Jilinocoides)dunhuaensis Chu,1983相近似,但后者翅长0.93 mm,径2室暗色,翅中4室、臀室无淡斑,PR 2.14,大额齿19枚与本新种明显不同。中国库蠓属吉林亚属现知有6种,本文记述了该亚属6种吸血蠓在国内的市、县分布,主要鉴别特征的测量值,编制了该亚属的分类检索表,绘制了6种雌性蠓种的形态特征图。结论中国库蠓属吉林亚属现知6种,为该亚属的分类提供了参考依据。

Objective To investigate and research the classification and species distribution of Culicoides(Jilinocoides)in China.Methods The blood sucking midges were captured with light traps from the pigpens and cattle pens in Xunke County,Heilongjiang Province of China in 2022.The species of blood-sucking midges were identified morphologically after the specimen had been slided in phenol-balsom.Relevant literature was reviewed.Results A total of 10000 hematophagous midges which including 12 species of Culicoides were collected.A new species,Culicoides(Jilinocoides)subdunhuaensis sp.nov.,was described.The new species was closely similar to Culicoides(Jilinocoides)dunhuaensis Chu,1983,but the latter one had the characteristics that the wing length 0.93mm,second radial cell dark,the cell M4 and cell A of without pale spot,palpal ratio 2.14,and mandible with 19 teeth.These characteristics were significantly different from Culicoides(Jilinocoides)subdunhuaensis sp.nov.Based on literature review,there were a total of 6 known species under Culicoides(Jilinocoides)in China.The distribution of the known species in China and the mean values of certain numerical characters were recorded.The key list and morphological feature figures of the female specimen of Culicoides(Jilinocoides)were provided.Conclusion There were 6 species known under Culicoides(Jilinocoides)in China,and the investigation results provided a reference for the classification of this subgenus.
