Pseudaspidapion botanicum sp. n. from China is described and figured. Its host plant is Grewia biloba G.Don var. parviflora (Bunge) Hand.-Mazz (Malvaceae: Grewioideae). The genus Harpapion Voss, 1966 is recorded as new for China and Vietnam and two comb. n. are proposed: Harpapion vietnamense (Korotyaev, 1985) (from Aspidapion) and H. coelebs (Korotyaev, 1987) (from Pseudaspidapion). A key to the known species of the genus Pseudaspidapion from China is presented.We thank Marek Wanat for kindly providing us references and many good advices, Boris A. Korotyaev for lending paratypes, Steven R. Davis for doing the linguistic review before submission, Yang Ganyan for collecting specimens, Zhou Dakang for providing information about the host plants, Yin Ziwei and Nico M. Franz for providing the brush-pencil Plug-ins of Adobe Illustrator. We also thank two anonymous reviewers whose suggestions considerably improved our work.
