ABSTRACT
Fairyfly (Hymenoptera, Mymaridae) egg parasitoids of the tea green leafhopper Empoasca (Matsumurasca) onukii Matsuda (Hemiptera, Cicadellidae), an economically important pest in Asia of the tea plant, Camelliasinensis, were identified from specimens reared in Japan. Using a combination of genetic and morphological evidence, Anagrus (Anagrus) rugmanjonesi Triapitsyn & Adachi-Hagimori, sp. n., is described and illustrated. It is shown to be different from the most similar A.turpanicus Triapitsyn & Hu, an egg parasitoid of a leafhopper pest of cultivated grapes which is known from Xinjiang Uyghur Autonomous Region in China. Mitochondrial and nuclear ribosomal DNA sequence data provide clear evidence for the separation of A.rugmanjonesi from A.turpanicus and other members of the Anagrusincarnatus Haliday species complex. A key to females of the Japanese species of Anagrus Haliday is given. Two other species of Mymaridae, Aresconenocki (Subba Rao & Kaur) and Stethyniumempoascae Subba Rao, are also identified, albeit the latter one only tentatively. Both latter taxa are newly recorded from Japan, and E.onukii represents their new host association.
