Notes on the genus ismarus Haliday (Hymenoptera, Diapriidae) from China

Abstract

The Chinese species of the genus Ismarus Haliday, 1835, are revised for the first time. Three new species from the Oriental region of China and belonging to I. halidayi-group are described and illustrated: Ismarus longus sp. n., I. nigritrochanter sp. n. and I. parvicellus sp. n. Two species are newly reported for the Chinese fauna: Ismarus dorsiger (Haliday, 1831) and I. halidayi Foerster, 1850. A key to the Chinese species of the genus is provided. The type specimens are deposited in the Hymenopteran Collection of South China Agricultural University, Guangzhou (SCAU). © Jing-xian Liu et al.
