Abstract:This is a part of the cooperative project-studies on biological control of Tamarix insect pests between the Chinese Academy of Agricultural Sciences,Ministry of Agriculture,People’s Republic of China and the Agricultural Research Service,Department of Agriculture,United States.Totally,362 leaf hoppers on Tamarisk and other plants were collected in Northwestern China from 1992 to 1994. Among them 4 species are new to science.The type specimens are deposited in the Insect Collections of Anhui Agricultural University.The new species are diagnosed as follows.1.Idiocerus kuohi Cai,sp.nov.(Fig.1) Similar to I. ulmus Fang,but differs from the latter in the smaller size,the brownblack face and the form of aedeagus. :Length 3.0mm,incl. tegm. 5.0mm. Holotype (8059),Xinjiang,15km NE Aksu,11515km,9 July 1992,Wang Ren & C.J.DeLoach,sweeping Elaeagnus angustifolia.2.Circulifer xinjiangensis Cai,sp. nov.(Fig.2)Externally as C. obscurinervis Lindberg,but differs in the smaller size and the structure of aedeagus. :Length 2.0 mm,incl. tegm. 2.9 mm.
