【Abstract】 A new genus, Paraphyllocoptes, and five new species, Paraphyllocoptes shiwanshanensi (type species: Paraphyllocoptes), Epitrimerus piper, Phyllocoptes machilus, Vasates guangxiensis and Disella cylindrokeluphae are described from Guangxi Zhuang Autonomous Region,China. Type specimens are deposited in the College of Agriculture, Guangxi University. All measurements are given in micrometers.Paraphyllocoptes gen.nov.Spindleform, shield with anterior lobe, dorsal tubercles situated in front of hind margin, dorsal seta pointing inward and backward, seta on genu of hindlegs absent, featherclaw simple, 6-rayed. Thanosome with arcuate tergites. Coxae and ventral setae present.Type species: Paraphyllocoptes shiwanshanensis sp. nov. Etymology. The genus name is derived from the name of the genus “Phyllocoptes”, and para,Greek.Remarks. This new genus belongs to Phyllocoptinae. It resembles Phyllocoptes Nalepa, 1889, but can be distinguished by seta on genu of hindlegs absent and dorsal setae pointing inward and backward.[KH*2D]1 Paraphyllocoptes shiwanshanensis sp.nov.
