The present paper describes four new species of the genus Helina from Qinghai, China, i.e. Helina alpigenus sp. nov., Helina apicicauda sp. nov., Helina bispina sp. nov. and Helina largideleta sp. nov. All type specimens are deposited in the Institute of Zoology, Chinese Academy of Science. 1 Helina alpigenus sp. nov. (Figs.1-4) This new species resembles Helina prominenicauda Wu, 1989, but it differs from the latter in the pra present, about half length of the second notopleural bristle, knees orange, hind tibia with a row of setae on middle section of posterior surface; distal part of cerci narrower. Holotype♂, Batang, Yushu, Qinghai, 4100m, 22 June 1964, by WANG Shu-Yong; paratype 1♂, same data as holotype, 2♂♂, Guinan, Qinghai, 3200m, 13 June 1957, by ZHANG Yi-Ran.2 Helina apicicauda sp. nov. (Figs.5-8) This new species is similar to Helina latitarsis Ringdahl, 1924, but it differs from the latter in the male eyes bare; pra absent; mid tibia with 2 ad and 2 p setae; surstyli slender, apical part of cerci narrow. Holotype♂, Batang, Yushu, Qinghai, 4200- 4500m, 15 June 1964, by WANG Shu-Yong.3 Helina bispina sp. nov. (Figs.9-11) This new species is allied to Helina truncata Fang et Fan, 1987, but it differs from the latter in the male frontal vitta at the narrowest point about as wide as fronto-orbital plate; pra about 2/5 length of the second notopleural bristle; surstyli slender, subapical part of cerci narrower. Holotype♂, Yushu, Qinghai Province, 3750m,12 June 1964, by WANG Shu-Yong; paratype 1♂, same data as holotype.4 Helina largideleta sp. nov. (Figs.12-15) This new species is similar to Helina deleta (Stein, 1914), but it differs from the latter in the male parafacial 1.5 times as wide as the width of antennal flagellomere; body moderately wide, abdomen ovate, tergites 3, 4 and 5 each with a pair of large quadrate spots; outer projections of apical part of cerci rather wider and larger in posterior view. Holotype♂, Batang, Yushu, Qinghai, 4200- 4500m, 15 June 1964, by WANG Shu-Yong.
