【Abstract】 In this paper four new species of Calliphorini collected from mountainous region of western Sichuan Prov. during 1981～1990 are described. The holotype specimen of the first species is deposited in the institute of Entomology, Shenyang Normal University, Shenyang, and those of the others are deposited in the Shanghai Institute of Entomology, Academia Sinica, Shanghai, China. 1. Paradichosia mingshanna sp.nov.(Fig.1～5) ♂:Body length 9.0mm. This new species is closely related to Paradichosia tsukamotoi (Kano,1962) but differs from the latter in:Eyes densely covered with hairs; male cercus expanded sidely and separated each other on basal three fourths in posterior view; the distal part of paraphallus bent forward in obtuse angle in lateral view; surstylus wider than usual form in lateral view. ♀:Unknown. Holotype ♂, Mt. Ment(1 450m; 30°03′N,103°01′E),Mingshan County, Sichuan Prov., 29-Ⅳ-1987,Coll.by Feng Yna. 2. Gymnadichosia aterifemora sp.nov.(Fig.6～10) ♂:Body length 6 5mm. This new species is closely related to Gymnadichosia pusilla Villeneuve, 1927, but differs from the latter in:Femora almost wholly fuscous black except for the distal apices yellow; pregonites on basal part straight in lateral view; hypophallus on basialula developed; inner margin of surstylus with long hairs basally. It is also closely related to Gymnadichosia pusilla tribulis Villeneuve, 1933, but differs from the latter by having scutellum on both of lateral and ventral surfaces yellow; interfrontalia present. ♀Unknown. Holotype ♂, Mt. Paoma (2 800m; 30°07′N;101°58′E), Kangding, Sichuan Prov., 01-Ⅸ-1982, coll.by Feng Yan; paratype 1 ♂, 10-Ⅶ-1986, same as holotype. 3. Bellardia peopedana sp.nov.(Fig.11～15) ♂:Body length 5.0mm. This new species is closely related to Bellardia menechma (Séguy, 1934),but differs from the latter by having the lateral lobe of 5th sternite On postinner angle squarely; male cercus coalescent on basal half in posterior view; pregonites slightly an isosceles triangle in profile in lateral view; surstylus subapical part on postmargin not protruding; paraphallus of aedeagus slender and longer on both of pieces left and right, and further separated each other in posterior view. ♀:Unknown. Holotype ♂, Yaan(Weiganding, 800m;29°59′N,102°57′E),Sichuan Prov.,29-Ⅲ-1981,coll. by Feng Yan; paratypes 2 ♂♂, 24-Ⅲ-1981, same locality and collector as holotype. 4. Onesia occidentalis sp.nov.(Fig.16～20) ♂:Body length 7 0～10 0mm; body and legs black. This new species is closely related to Onesia flora Feng, 1998, but differs from the latter by having 9th tergite not backward elongate into cover surstylus; surstylus long plank-like, that is about 6.0 times of its width in lateral view; distal part of aedeagus apicialula is ladder-shaped in posterior view. ♀:Unknown. Holotye ♂,Mt. Erlang (Forest Farm, 2 750m; 29°54′N,102°08′E),Sichuan Prov., 20-Ⅷ-1984,coll. by Feng Yan; paratypes; 12♂♂,same as holotype; 1♂, 25-Ⅴ-1984;1♂,14-Ⅸ-1990,above same locality and collector as holotype; 4♂♂, Mt; Jiaoding(3 550m;29°23′N,102°51′E),Sichuan Prov., 01-Ⅷ-1986, Same collector as holotype.更多还原
