Three new species of the genus Mileewa, M. huapingana sp. nov., M. lamellata sp. nov. and M. coeomacula sp. nov., are described from Guangxi, Sichuan and Guizhou Provinces of China in the paper. The type specimens are deposited in the Institute of Entomology, Guizhou University. 1 Mileewa huapingana sp. nov. （Figs. 1-5, 16） Body length （incl. tegm. ）： ♂ 5.5-6.0mm. This species is quite similar to M. ussurica Anufriev and M. rufrvena Cai et Kuoh in appearance, but it can be distinguished by： pygofer appendage undivarecate; aedeagus with two paired spiniform processes, the two spiniform processes not closed basally and the apical one stronger than the preapical one. Holotype ♂, Huaping （25°18＇ N, 110°18＇ E, alt. 900 m）, Guilin County, Guangxi Province, China, 31 july 2007, coll. by MENG Ze-Hong. Paratype 1 ♂ , same data as holotype. 2 Mileewa lamellata sp. nov. （Figs.6-10, 17） Body length （ind. tegra. ）： ♂ 4.1-4.4 mm, ♀ 4.3-4.6 mm. This species is allied to M. mira Yang et Li, but can be readily distinguished from the latter by： crown without yellow-white stripe; scutellum apex black; apical cell 1st base of forewing with a white patch; pygofer appendage median area with lobiform extension; aedeagus anterior portion pedicel short, apex cuspidal, anterior median region dorsad dilatata and the dilatata area apex produced into paired process; subgenital plate preapical area inner margin with small setae and apex with unique long setae. Holotype ♂, Huaping （25°18, N, 110°18, E, alt. 900 m）, Guilin County, Guangxi Province, China, 30 July, coll. by MENG Ze-Hong. Paratypes： 4 ♂♂, 5 ♀♀, same data as holotype. 3 Mileewa coeomacula sp. nov. （Figs.11-15, 18） Body length （incl. tegm. ）： ♂ 5.0-5.4 mm, ♀ 5.7 mm. This species is similar to M. branchiuma Yang et Li, but differs in the crown apex without yellow-white stripe; forewing fore margin preapical area with a white patch; aedeagus basal area not dorsad growing a long process. Holotype ♂ , Mayanghe （28°30＇ N, 108°30＇ E, alt. 800m）, Yanhe County, Guizhou Province, China, 27 Sep. 2007, coll. by MENG Ze-Hong. Paratypes： 1 ♂ , Shuimogou （32°24＇ N, 105°48＇ E, alt. 1 100m- 1 200 m）, Guangyuan County, Sichuan Province, China, 17 Aug. 2007, coll. by MENG Ze-Hong; 1 ♀, Shuimogou （32°24＇ N, 105°48＇ E, alt. 1 100 m- 1500m）, Guangyuan County, Sichuan Province, China, 18 Aug. 2007, coll. by XING Ji-Chun.
