Abstract
A new gall wasp species, Plagiotrochus hepingensis sp. n. is described from Hunan Province, China that forms integral galls on the central vein on the abaxial leaf blade surface of Quercus (Cyclobalanopsis) glauca (Fagaceae). The morphological characters of the new species are described and photographed and data on the diagnosis, distribution, and biology are given. Additionally, a specific region of the COI gene was amplified using the primers HCO-2198 and LCO-1490 and compared for both the new species and Plagiotrochus masudai Ide, Wachi & Abe.
