The genus Ismarus Haliday from China is revised. Six species are recognized, of which two species are described as new: Ismarus areolatus Chen, sp. nov., and Ismarus paradorsiger Chen, sp. nov. By examining the pits along the anterolateral margin of mesoscutum and comparing them with the typical notauli in Diapriidae, we conclude that the so-called reduced notauli in Ismarus are actually foveae of the mesoscutual suprahumeral sulcus. An updated key to the Chinese species of the genus is provided.
