山西省芦芽山自然保护区有瓣蝇类物种多样性

Species diversity of Calyptratae in Luyashan Nature Reserve of Shanxi province

目的调查山西省芦芽山自然保护区有瓣蝇类的种数、特有物种多样性及区系特征。方法采用生物多样性研究方法及昆虫分类学原理与方法。结果在山西省芦芽山自然保护区发现有瓣蝇类10科96属243种,其中蝇科,无论在属级水平还是在种级水平,均占有较大优势,分别占该保护区已知属数和种数的42.86%和39.51%;在芦芽山自然保护区已知的243种有瓣蝇类中古北界种102种,占该保护区分布种数的41.98%,其次是古北+东洋界种58种,占23.87%,连同古北界与其他界共同分布的种共占96.30%;尚有特有种9种,占该保护区分布种数的3.70%。结论山西省芦芽山自然保护区有瓣蝇类物种多样性较高,其区系特征是以古北界区系成分为主兼具明显的地区特有化特征。

Objective To determine the number of species, diversity of endemic species and faunal characteristics of the Calyptratae fauna in Luyashan Nature Reserve of Shanxi province. Methods The biological diversity in the region was studied based on entomological classification principles and related approaches. Results A total of 243 species, 96 genus and 10 families of Calyptratae were found in the nature reserve, among which Muscidae share the highest diversity, accounting for 42.86% and 39.51% of the known Calyptratae genera and species in the region, respectively. In Luyashan Nature Reserve, there were 102 species of Palearctic out of 243 known Muscidae, accounting for 41.98% of the overall species in this region, followed by 58 Palearctic and Oriental species, accounting for 23.87%. These species, together with the Palaearctic and the other commonly distributed, accounted for 96.30% of the overall species. In addition, nine endemic species were found, making up 3.70% of the known species in the area. Conclusion In Luyashan Nature Reserve of Shanxi province, the Calyptratae fauna has high species diversity and is characterized by Palearctic elements and significant regional features.
