Two new genera and four new species of eriophyoid mites in the tribe Anthocoptini from south China are described and illustrated in this paper: Agenusetacus fagraea gen. nov. & sp. nov. associated with Fagraea ceilanica Thunb. (Loganiaceae), Kudzuacarus puerariaes gen. nov. & sp. nov. found on Pueraria montana (Lour.) Merr. (Leguminosae), Tegolophus pittosporumi sp. nov. on Pittosporum pentandrum (Blanco) Merr. (Pittosporaceae) and Tegolophus lagerstroemiae sp. nov. on Lagerstroemia speciosa (L.) Pers. (Lythraceae). The new genus Kudzuacarus differs from all genera of Anthocoptini by the opisthosoma with five narrow furrows bound by six ridges, the middle two ridges merged into one ridge at two-thirds of dorsal opisthosoma. The following features distinguish the new genus Agenusetacus from the others: both anterolateral setae on coxisterna I and antaxial genual setae absent on leg II. All new species described here, were vagrants on their respective host plant causing no visible damage.
