The present paper describes and illustrates four new species of the genus Helina Robineau-Desvoidy,1830 from China,i.e.Helina borehesperica sp.nov.,H.xingkaihuica sp.nov.,H.dasyouraea sp.nov.and H.acocerca sp.nov.The type specimens are deposited in the Medical Entomological Collection,Institute of Microbiology and Epidemiology AMMS,Beijing,China.1 Helina boreheaperica sp. nov. （Figs.1-4） Tills new spedes resembles H. harbinensis Zhang et Ma, 1997. but can be distinguished from the latter by the following characters： 1 ） abdomen black dark wholly on syntergite 1 ＋ 2 dorsal, but the latter with a pair of lateral black spots; 2） parafacialia about 1.3 times as wide as antennal flagellomere, but the latter about 2 times as wide as one; 3） mid femur with end broke of pv on basal half. but the latter with spinelike of one; 4） surstyfi of male 2 dmes as wide as its long, but the latter have been equal on each other in lateral view; 5 ） anal cerci rectangularly, but the latter cross-width. Holotype ♂ , Manasi （ 44°28＇N, 86°30＇E; 2 100m）, Xinjiang, 20 June 1976, coll. by YE Zong-Mao. Etymology. The specific name refers to the type locality in northwest region of China. 2 Helina xingkaihuica sp. nov. （Figs. 5-8） This new species resembles to H. deleta （Stein, 1914）, but can be distinguished from the latter by the following characters： 1 ） frons about 1.8 times as wide as the frontal oceUar diameter, but the latter narrower than the one; 2 ） surstyli of male very short, shaped.A to crescent-moon in lateral view, and bided behind the anal cerci in posterior view, but the latter as long as anal cerci, and cylinderlide in lateral view, that＇ s seating the both sides of anal cerci in posterior view; 3） 1st to 3rd tarsomeres of anterior leg with a pair of feelling-hairs respectively, but the latter without it. Holotype ♂ , Xingkai Lake （45°20＇N, 133°10＇E）, 150m; Heilongjiang Prov., 24 June 1971, coll. by YE Zong-Mao. Etymology. The specific name refers to the type species locality in Xingkai Lake, Heilongjiang Prov. of China. 3 Helina dasyouraea sp. nov. （Figs.9-12） This new species resembles H. prominenicauda Wu, 1989, but can be distinguished from the latter by the following characters： 1 ） length of lateral lobe of 5th sternite as 1/6 as basal part, but the latter about equal with each other; 2） 7 ＋ 8 synstemite with setae-mats on dorsal surface, but the latter without one; 3） length of surstyfi of male longer than the anal cerci markedly, but the latter about as long as one in lateral view; 4） anal cerci of male without inner process on apical part in posterior view, but the latter with it. Holotype ♂ , Manasi （ 44°28＇N, 86°30＇E; 2 100m）, Xinjiang, 20 June 1976, coll. by YE Zong- Mao. Etymology. The specific name refers to the caudal part of dorsal surface of abdomen with setae-mats. 4 Helina acocerca sp. nov. （Figs. 13-16） This new species resembles to H. cinerellioides Fang et Fan, 1992, but can be distinguished from the latter by the following characters： 1 ） eyes bare, but the latter densely covered with long hairs; 2） cross veins r-m and m-m without doud, but the latter with ones; 3） apical part of anal cerci without inner of lateral process in posterior view, but the latter with it; 4 ） surstyli of male is knifelike on profile in lateral view, but the latter cylinderlike. Holotype ♂ , Manasi （ 44°28＇N, 86°30＇E; 2 loom）, Xinjiang, 15 June 1976, coll. by YE Zong- Mao. Paratypes 2 ♂♂ , same as holotype. Etymology. The specific name refers to the anal cerci of type species sharped and compressed on distal part in posterior view.
