Leaf-mining moths of the genus Phyllonorycter Hübner (Lepidoptera: Gracillariidae: Lithocolletinae) associated with Malvaceae in China, with descriptions of one new species

摘要

Until recently, only one species of Phyllonorycter Hübner, 1822 has been known to feed on Malvaceae in China, i. e. the lime leaf miner P. issikii (Kumata, 1963) associated with Tilia spp. Here we describe a new species, Phyllonorycter bilobae T. Liu sp. n., found in Shaanxi and Shandong provinces in China feeding on Grewia biloba var. biloba G. Don and G. biloba var. parviflora (Bunge) Hand.-Mazz. (Malvaceae). Images of the adult, male and female genitalia, host plant, and the leaf mines of the new species are provided. Additionally, detailed distribution data of P. issikii in Shandong province (China) is given.
