【Abstract】 Three new species of Psilotreta are described and illustrated from China,i.e.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 slightly 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 monophyletic,as evidenced by two synapomorphies:absence of DC on male forewings and with R3,R4 and R5 sharing the same base.更多还原
