Abstract
Until recently, no species of Phyllonorycter Hübner, 1822 had been recorded to feed on Juglandaceae in China. In this study, we describe two new species, P. stenopterae Lu & Liu, sp. nov. and P. tumoris Lu & Liu, sp. nov., both discovered in Shandong Province, China, feeding on Pterocarya stenoptera C. DC. (Juglandaceae). Additionally, this paper provides the first record of P. pterocaryae (Kumata, 1963) in China, along with its newly identified host plant, Pterocarya stenoptera. Detailed images of the adults, genitalia, pupae, host plants, leaf mines, and DNA barcode data of the new species are presented.
