摘　　要：本文的三新种为若尔盖犹伊螨Eviphis ruoergaiensis sp.nov.,南充犹伊螨E.nanchongensis sp.nov.,王朗犹伊螨E.wanglangensis sp.nov.。This paper deals with three new species of the genus Eviphis from Sichuan, China. All the type specimens are deposited in the Sanitation & Anti-Epidemic Station of Sichuan Province. 1. Eviphis ruoergaiensis sp. nov. (figs. 1-5)This new species is similar to Eviphis himalayaensis Ma et Piao and Eviphis ostrinus (Ko-ch), in having one invaginated incision and one lyrifrom organs on the slender peritrematal plate, but differs from them in: 1) without small sclerites behind the genito-ventral plate; 2) tri- tosternal base narrow triangular in shape; 3) dorsal setae 26 pairs in number; 4) ventral setae 10 pairs in number.Holotype ♀ and paratypes 18♀♀ collected from Tahgke, Ruoergai County of Sichuan Province (33°23.’N, 102°28’E), June-September 1960, off rat nest and Myospalax fontanieri.2. Eviphis nanchongensis sp. nov. (figs. 6-10)This new species resembles Eviphis huainanensis Wen, in having slender peritrematal plate, St3 and posterior setae of coxae Ⅱ and Ⅲ spur-like, but differs from the latter in the following characters: 1) dorsal setae 29 pairs (vs. 30); 2) ventral setae 7 pairs (vs. 9); 3) sternal plate subrectangular in shape; 4) anal plate pear-like in shape.Holotype ♀ was found from Nanchong County, Sichuan Province (30°47’N, 106°05’E) in the house of a patient, August 1963.3. Eviphis wanglangensis sp. nov. (figs. 11-15)This new species is near to Eviphis convergens Berlese, in having broad peritrematal plate, but differs from the latter in the following characters: 1) peritrematal plate with two invagin-ated incisions and three lyriform organs; 2) nine pairs of ventral setae in the region posterior to coxae Ⅳ; 3) one pair of platelets behind the genitoventral plate.Holotype ♀ and paratypes 3 ♀♀ were collected from Wanglang Natural Reserves, Pingwu County of Sichuan Province (32°59’N, 104°06’E) in June 1983 of Apodemus chevrieri and Eothenomys eva.
