Faunal study on syrphids of Lishan Nature Reserve in Shanxi Province

Among the syrphids samples collected from Lishan Natural Reserve as part of an ongoing survey of Syrphids fauna in Shanxi Province,107 species,47 genera and 11 tribes in three subfamilies of Syrphidae were recognized,in which 69 species and 30 genera of 4 tribes were identified to belong to the biggest subfamily Syrphinae,37 species and 16 genera of 6 tribes were Eristalinae,and only one species from Mierodontinae. Among them,one species,Spilomyia manicata( Rondani,1865),was recorded from China for the first time,64 species were newly recorded to Shanxi Province,and 7 species were undefined. The records of Syrphidae in Shanxi Province reached 159 species according to the survey. Based on the analysis of 100 known species and 47 genera in the fauna of Syrphids from Lishan Natural Reserve,the results showed that Palaearctic region and Oriental region were predominant,and elements of Palaeretic species were slightly more abundant than those of Oriental species. According to the distributional types,the subfamily Syrphinae multizoogeographical genera are predominant( 70. 21%),while the proportion of single-zoogeographical genera is relatively low. The results showed that the fauna of Syrphids of the Lishan Natural Reserve in Shanxi Province is transitional and complex.
