中国蚤蝇亚科物种多样性及分布格局探讨(双翅目:蚤蝇科)

采用世界及中国动物地理区系划分方法对中国蚤蝇亚科昆虫的分布格局、区系及多样性进行了探讨。中国已知17属,58种,其中特有种27种,占中国已知种数的46.55%。在世界动物地理区系中,以东洋区成分占有优势。中国蚤蝇亚科存在10种比较明显的分布类型,以全北界和东洋界共有分布型和世界广布型占优势;其次为中国特有分布型和东洋界特有分布型;跨多个动物区分布的属数量呈下降趋势。蚤蝇亚科昆虫分布特点为自南向北物种丰度递减;从东到西,特有类群增多。

Species Diversity and Distribution Patterns of the Phorinae in China (Diptera: Phoridae)

The distribution pattern,fauna and diversity of the subfamily Phorinae in China were studied by using the method of zoogeographical region.The known species and genera in China are 58 and 17,of which the endemic species is 46.55%.In terms of the world geographical distribution,groups in the Oriental Region are distinctly predominant.The distribution patterns of genera are segregated into 10 categories,among which the Holearctic and Oriental Region and the widely distributed pattern is predominant.The second is Chinese endemic distribution pattern and Oriental endemic distribution pattern.The genera of multiregional distribution pattern tends to being decreased.The feature of distribution is that the abundance of species is decreased gradually from the south to the north of China.The endemic groups is increased from the east to the west of China.
