记述栉眼蚤科Ctenophthalmidae Rothschild, 纤蚤属Rhadinopsylla Jordan et Rothschild, 1912角头纤蚤亚属Actenophthalmus C. Fox, 1925的2新种, 标本采自宁夏六盘山自然保护区（106°11＇N,35°45＇E）短尾鼩Anourosorex squamipes体上,模式标本均保存于军事医学科学院微生物流行病研究所医学昆虫标本馆.

The present paper deals with two new species of Rhadinopsylla Jordan et Rothschild, 1912 from Ningxia, China. Specimens were collected from a nature conservation in Liupanshan Mountain （106° 11 ＂N, 35°45 ＂E） of Anourosorex squamipes. The type specimens are deposited in the Collections of Medical Entomology, Beijing Institute of Microbiology and Epidemiology, Beijing, China. Rhadinopsylla （Actenophthalmus） liuzhiyingi sp. nov. （ Figs. 1-4） Diagnosis： The new species is similar to Rhadinopsylla （Actenophthalmus） angusta Tiflov, 1937, but differs from the latter by the following characters ： In male （ Fig. 3） , 1 ） the movable process slender, its anterior margin almost straight, and only posterior margin curved ; 2） distal arm of st. IX slender and longer, bigger in the middle part, narrow and sharp in the apex ; In female （ Fig. 2） , 3） the posterior margin of st. VII with wider sinus. Holotype ♂ , Body length 2.3 mm, paratypes 1 ♂ , 1 ♀ , Body length 2. 1 mm and 2.3 mm respectively, collected by BAI Xue-Li on Oct. 14 and 25, 2006 from Liupanshan Mountain nature conservation （2 580-2 800 m） of Ningxia Hui Autonomous Region. Etymology. New species is named in honor of late professor LIU Zhi-Ying for his excellent contributions to the research on Siphonaptera in China. Rhadinopsylla （Actenophthalmus） liguizhenae sp. nov. （ Figs. 5-8 ） Diagnosis： The new species is similar to Rhadinopsylla （Actenophthalmus） rothschildi loft, 1940, but may be distinguished by the following characters： In male, 1 ） a long thick bristle of sub-dorsal margin of clasper situated far from the dorsal margin, and the movable process slightly shorter than immovable process ; 2） the apical margin of distal arm of st. IX somewhat flat; In female, 3） the posterior margin of st. VII with a narrow and sharp sinus, its dorsal lobe large with selerotization striavinm and abdominal lobe smaller and shorter than dorsal lobe obviously. Holotype ♂ , body length 1.8 mm, paratypes 1 ♂ , 1 ♀ , Body length 2.3 mm and 2.4 mm respectively, collected by BAI Xue-Li on Oct. 17 and 24, 2006, from Liupanshan Mountain nature conservation （2 000-2 410） of Ningxia Hui Autonomous Region. Etymology. New species is named in memory of late professor LI Gui-Zhen for her outstanding contributions on classification of Siphonaptera in China.
