Five new species of eriophyoid mites of the subfamily Phyllocoptinae from China are described and illustrated, namely Tegolophus liquidambaricola sp. nov. (Anthocoptini) infesting Liquidambar formosana Hance var. (Hamamelidaceae), Abacarus paniceus sp. nov. (Anthocoptini) infesting Panicum notatum Retz. (Poaceae), Tetra armato sp. nov. (Antho- coptini) infesting Zanthoxylum armatum DC. var. armatum (Rutaceae), Pentaconvexus lambertianus sp. nov. (Acaricalini) infesting Rubus lambertiannus Ser. (Rosaceae) and Parategonotus acanthopanacinus sp. nov. (Tegonotini) infesting Acanthopanax gracilistylus W. W. Smith (Araliaceae). All these new species are free-living on the undersurface of leaves and cause indistinctive damage to the host plants.
