Two new Diptacus and one new Trimeroptes species (Acari: Diptilomiopidae) from China

Abstract

Two new Diptacus species and one new Trimeroptes species (Acari: Eriophyoidea: Diptilomiopidae) are described and illustrated from China: Diptacus suichangensis sp. nov. on Aralia chinensis L. (Araliaceae) and Diptacus pyracanthae sp. nov. on Pyracantha fortuneana (Maxim.) Li (Rosaceae), and Trimeroptes longlinensis sp. nov. on Carpinus sp. (Betulaceae). These new species were found to be vagrant on the lower surface of their associated plants leaves, albeit with no apparent damage observed.
