中国阳蝇属区系研究(双翅目:蝇科)

A study on faunistic distribution of genus Helina in China

阳蝇属迄今在全世界已知400余种,本文报告了阳蝇属的属征、生物学及分类概况.在已有标本采集记录和资料的基础上,讨论了我国阳蝇属已知种的区系分布特点.结果表明我国阳蝇属种类极其丰富,已知176种,约占世界阳蝇已知种数的44%;在世界动物地理区划中,古北界种81种,东洋界种73种,古北和东洋界共同种13种,全北界种9种;在我国动物地理区划中,西南区、华北区和东北区的种类最为丰富;在我国已知的阳蝇中有140种为地方性种.

There are 400 known species of Genus Helina in world so far,this paper reports generic character,bionomics and classification of Genus Helina.Specimen records and published literature were used to investigate faunistic distribution characteristics of known species in the china.The results indicate that species of Genus Helina in China are plentiful with 176 known species,it is 44 percent of known species in the world.In China,81 species have a Palaearctic distribution and 73 species have a Oriental distribution.There are three regions,including South Western China,North China and Northeast China,that have high species diversity.140 species are the proportion of the endemic species.
