| abstract | During a field survey in 2019, three new species of eriophyoid mites were collected from Melicope pteleifolia, in Rongan county, Guangxi Zhuang Autonomous Region, China. Aceria melicope sp. nov. causes blister-like galls on the upper side of the leaves, forming thickened, wrinkled and distorted leaves. Phyllocoptruta pteleifoliae sp. nov. and Diptilomiopus ronganensis sp. nov. are vagrant on the leaves and no apparent symptom was observed. |
