Seven tribes are all exist in Afrotropical region, 4 tribes in palearctic, 3 in Oriental and2 in Australian region respectively. 7个族在非洲区均有分布,古北区有4个族、东洋区3个族、澳洲区2个族。
Similarity coefficient analysis of the four regions shows that the similarity from greater to smaller is: Oriental, Palearctic, Australian and Afrotropical Regions; 依种类分布情况对4大动物区的相似性分析表明,东洋区与古北区关系最为密切,其次是澳洲区,与非洲区的相关性较小,这与地球演化历史是相吻合的。
