Abstract

A new Palaearctic species of Anagrus Haliday (Hymenoptera, Mymaridae), A. (Anagrus) dmitrievi Triapitsyn & Hu, sp. n., is described, diagnosed, and illustrated from Xinjiang Uyghur Autonomous Region of China. It was reared from parasitized eggs of the leafhopper Zyginidia (Zyginidia) eremita Zachvatkin (Hemiptera, Cicadellidae) on leaves of maize. A key to the 21 named species of Anagrus known from China is provided. Zyginidiaeremita is an important economic pest in Xinjiang, occurring in approximately 90% of maize fields. The phenology and life cycle of Z.eremita is summarized. Parasitism of its eggs by A.dmitrievi in maize fields was 12–75 % (average about 38 %), thus making it a rather effective natural enemy.
