P. apiculata sp. nov., P. superposita sp. nov. and P. monacantha sp. nov., bringing the number of Chinese Psilotreta species to 32, about 50 % of the world fauna of the genus （67 species）. Psilotreta apiculata group, including P. apiculata sp. nov. and P. superposita sp. nov., is recognized by three synapomorphies： the maxillary palp with segment Ⅱ slighdy shorter than segment Ⅰ, and absence of both intermediate appendage of X and paramere. Psilotreta monacantha group, including P. monacantha sp. nov. only, is also probably monophylefic, as evidenced by two synapomorphies： absence of DC on male forewings and with R3, R4 and R5 sharing the same base.
