Abstract: This paper described that three new species of the genus Helina RobineauDesvoidy,1830 from China,namely H.meiguica sp.nov.,H.guica sp.nov. and H.dianica sp.nov.. All type specimens are deposited in the Medical Entomological Collection Gallery,Institute of Microbiology and Epidemiology,AMMS,Beijing,China.1 Helina meiguica sp.nov.(Fig.1)Male: Body length 8.0 mm.This new species is similar to Helina yaanensis Feng et Xue,2003,however,the postscutum of the former without a fuscous mid stripe but the latter's with it; wing near to r-m and m-m cross veins of the former slightly clouded,but of the latter cloudless; surstyli of the former crescentshaped in lateral view,and hiding behind cerci in posterior view,but the latter's cylindershaped,and at the sides of cerci in posterior view.Female: Unknown.Holotype ♂,Sichuan: Meigu (1 800 m; 28°17′N,103°10′E),10 July 1975,coll. by Ni Tao.2Helina guica sp.nov.(Fig.2)Male: Body length 7.0 mm. This new species is similar to Helina longiquadrata Xue et Wang,1986,however,submedian stripe on scutum of the former not reach to scutellar sulcus,but the latter's reaching it; fore femur of the former yellow,that the latter's largely black; fore tibia of the former without P seta,but the latter's with one; cerci of male of the former round in profile in posterior view,but the latter's rectangle.Female: Unknown.Holotype ♂,Guangxi:Honggu (1 200 m),25 Mar.1979,coll. by Ye Zhongmao; paratype l♂,Guangxi:Muban (1 300 m),20 May 1957,coll. by Xue Jingmin,1♂,Yunnan:Kunming (1 800 m,25°04′N,102°38′E),07 Apr. 1953,coll. by Ye Zhongmao.3 Helina dianica sp.nov.(Fig.3)Male: Body length 9.0 mm. This new species is similar to Helina emeishanana Guan,Feng et Ma,2001,however,the submedian stripe on scutellar of the former reaching to scutrllar sulcus,but the latter's not reaching it; wing near to rm and mm cross veins of the former with clouds,but the latter's cloudless; the distal part of cerci of male of the former with one outer projection in posterior view and robust in lateral view,the latter's without projection in posterior view and gaunt in profile.Female: Unknown.Holotype ♂,Yunnan:Deqin (2 400 m; 28°15′N,99°08′E),21 July 1991,coll. by Pan Fenggeng.
