山西省棘蝇亚科区系特征及物种分化

Fauna characteristics and species differentiation of the Phaoniinae (Diptera:Muscidae)in Shanxi province

采用区系分析法、GIS技术及生物地理学研究方法,对山西省棘蝇亚科Phaoniinae昆虫进行区系特征分析及物种分化趋势研究。在所发现的山西省棘蝇亚科Phaoniinae昆虫2族4属92种中,从其区系构成来看,山西特有种和中国其他地区特有种分别占该地区已知种的36.96%和30.44%,二者合计占总数的67.40%,占绝对优势。其次为古北界种,占总数的13.04%。尚有部分典型的东洋界种的渗入。分析了该地区该类昆虫区系构成的特点,讨论了特有种物种分化的趋势。结果表明山西省棘蝇亚科昆虫物种的丰富、多样、特有性及物种分化剧烈等特点。

To do faunal characteristics analyse and species differentiation of Phaoniinae in Shanxi province. Methods： The investigation was conducted by insect taxonomy theory, biodiversity analysis and biogeography theory. Results： A total of 92 species, 4 genera and 2 tribes of Phaoniinae were found in Shanxi province. Domestic species of Shanxi and species from other province of China accounted for 36. 96% and 30. 44% separately of all known species of the Phaoniinae in China, combined accounted for 67. 40%; Palearctic species accounted for 13. 04%. There also have some oriental species invaded. This paper analyzes the characteristics of this kind of insect fauna composition in the region; the trend of domestic species differentiation is discussed. Conclusion： Results showed that the characteristics of Phaoniinae in Shanxi province were rich , various, endemism and with high species differentiation.
