Notes on braconid wasps (Hymenoptera, Braconidae) parasitising on Agrilus mali Matsumura (Coleoptera, Buprestidae) in China

Braconid parasitoids reared from Malussieversii and Malusdomestica trees in NW China infested by Agrilusmali Matsumura (Coleoptera, Buprestidae) are illustrated and discussed. Six species were found parasitising Agrilusmali in NW China, namely, Atanycolusivanowi (Kokujev) (Braconinae), Doryctesundulatus (Ratzeburg), Pareucorystesvarinervis Tobias, Polystenusrugosus Foerster, Spathiussinicus Chao, and Spathiusbrevicaudis Ratzeburg (Doryctinae). All listed species are newly recorded parasitoids of Agrilusmali. Pareucorystesvarinervis and Spathiusbrevicaudis are new records for the Chinese fauna, but Spathiusbrevicaudis has been recorded from Taiwan before. Both sexes of Spathiusbrevicaudis are redescribed here to allow inclusion in the recent revision of the Chinese Spathius species. An identification key to the six braconid parasitoids of Agrilusmali in NW China is provided.
