Species diversity of Calyptratae in Pangquangou Nature Reserve of Shanxi province

目的调查山西省庞泉沟自然保护区有瓣蝇类的种数、特有种及区系特征。方法采用昆虫学分类原理与方法。结果在山西省庞泉沟自然保护区发现有瓣蝇类6科64属142种。其中蝇科,无论在属级水平还是种级水平,均占有较大优势,分别占该保护区已知属数和种数的32.81%和49.30%。文中记录动物三界以上的广布种34种,占该保护区分布种数的23.94%,六界广布种5种,占该保护区分布种数的3.52%。特有种4种,占该保护区分布种数的2.82%。结论山西省庞泉沟自然保护区有瓣蝇类的区系特征是以古北界区系成分为主。

Objective To study the number of species, endemic species and faunal characteristics of Calyptratae in Pangquangou Nature Reserve of Shanxi province. Methods Entomological classification was used in the study. Results A total of 142 species, 64 genera and 6 families of Calyptratae were found in the nature reserve. Muscidae had the highest proportion at both genus and species levels, accounting for 32.81% of the known genera and 49.30% of known species in the region. Thirty-four cosmopolitan species distributing in 3 or more biogeographic realms were recorded, accounting for 23.94% of the known species in the area, as well as 5 cosmopolitan species which distributed in 6 biogeographic realms, accounting for 3.52%. Four endemic species were found, which accounted for 2.82% of the known species in the area. Conclusion The Calyptratae fauna in Pangquangou Nature Reserve of Shanxi province was mostly palaearctic.
