在入境船舶上采获毛蠓属一新种(双翅目:蠓科)

A new species of genus Dasyhelea Kieffer(Diptera:Ceratopogonidae) collected on an entry ship

该文报道了在秦皇岛港检疫锚地停泊的来自韩国的一艘入境船舶上捕获的输入性毛蠓一新种光阳毛蠓(Dasyhelea kwangyangi Nie,Yu et Bo sp.nov.)。该新种阳茎中叶和阳基侧突与纳赤台毛蠓(Dasyhelea nachitai Yu et Liu,2005)近似,但其阳茎中叶和阳基侧突端突均明显短于本新种。本新种尾器形态与Dasyhelea faciigera Kieffer,1924也很相似,但该种阳基侧突中突端部无缺裂与本新种鉴别。模式标本收藏于军事医学科学院微生物流行病研究所医学昆虫标本馆(北京市丰台区东大街20号,100071)。

A new species, Dasyhelea kwangyangi Nie, Yu et Bo sp. nov., was recorded, which was captured in an entry ship came from Korea at the anchorage of Qinhuangdao port. The aedeagus and parameres of the new species are closely allied to Dasyhelea nachitai Yu et Liu, 2005, but the latter is distinctly characterized by short aedeagus and apical dilation of parameres. The new species is also closely allied to Dasyheleafaciigera Kieffer, 1924, but no crena on the apical dilation of the median apophysis of parameres of the latter is significantly different from that of the new species. The type specimens are preserved in the medical insect specimens Museum, Fengtai East Street No. 20, Beijing 100071, China.
