在标本鉴定和文献汇总的基础上,对东北亚地区(包括朝鲜半岛、日本、俄罗斯远东地区、中国东北)的蜉蝣区系做了统计分析.结果显示,截至目前该地区已报道蜉蝣18科48属237种.其中俄罗斯远东地区的蜉蝣属种多样性最高,而从地区对比来看,朝鲜半岛和中国东北地区的蜉蝣区系最为相似(属种相似度分别为83%和64%).日本群岛蜉蝣区系相对独特,这可能是由于它长期与大陆分离而造成的.

The extant mayfly fauna of Northeast Asia (geographyically including Korea Peninsula, Japan, Far East Russia and Northeast China) is thoroughly investigated based on literatures and specimens. Totally 236 species in 48 genera 18 families have been reported from this area so far known. The highest generic diversity occurs in the Far East Russia, with a correspondingly highest specific diversity. The ephemeropteran faunas of the four regions are compared on both generic and specific levels, the result shows that Korea Peninsula and Northeast China mayfly faunas are more closely related (about 64% similarity on the specific level and 83% on the generic level). Compared with other places in Northeast Asia, the mayfly fauna of the Japanese archipelago on the specific composition represents some unique, it may due to long-term isolation.
