侧沟茧蜂一新种(膜翅目:茧蜂科:小腹茧蜂亚科)(英文)

A new species of the genus Microplitis Foerster from China (Hymenoptera: Braconidae: Microgastrinae)

报道侧沟茧蜂1新种,即毛脸侧沟茧蜂Microplitis hirtifacialis,sp.nov..该新种与棉铃虫侧沟茧蜂M.helicoverpae Xu et He相似,区别为:前者,单眼小,高三角形;1-R1分别为其至缘室端部和翅痣长的1.5倍和1.1倍;第1背板长为其最宽处的1倍.后者,单眼大,矮三角形;1-R1分别为其至缘室端部和翅痣长的1.1倍和0.7倍;第1背板长为其最宽处的1.7倍.研究标本均保存于福建农林大学益虫室.

The genus Microplitis Foerster 1862 from China was studied. One species Microplitis hirtifacialis sp. nov. was described as new to science. The new species is similar to Microplitis helicoverpae Xu et He, but is different from the latter as shown in following contrast： Microplitis hirtifacialis, sp. Nov., 1. ocelli small, in a high triangle; 2.1-R1 1.5 × and 1.1 × as long as the distance from its tip to the tip of marginal cell respectively; 3. tergite 1 1.0 × as long as wide in maximal breadth. Microplitis helicoverpae Xu et He 1.ocelli large, in low triangle; 2.1-R1 1.1 × and 0.7 × as long as the distance from its tip to the tip of marginal cell respectively; 3. tergite 1 1.7× as long as wide in maximal breadth. Types were deposited in the Beneficial Insects Lab., College of Plant Protection, Fujian Agriculture ＆ Forestry University.
