Two newly recorded genera Stenodyneriellus and Lissodynerus with three new species from China (Hymenoptera, Vespidae, Eumeninae)

Abstract

These two genera Stenodyneriellus Giordani Soika and Lissodynerus Giordani Soika are newly recorded from China. Three species, namely Stenodyneriellus similiguttulatus sp. n. from Yunnan, S. maolanensis sp. n. from Guizhou, and S. depressus sp. n. from Yunnan, are described and illustrated. Stenodyneriellus guttulatus (de Saussure, 1862) and Lissodynerus septemfasciatus feanus (Giordani Soika, 1941) are newly recorded and illustrated from China. A key to the Chinese species of Stenodyneriellus is provided.
