Data on mayfly fauna of transboundary basin of Khanka Lake and Razdolnaya River is presented. The basis of the fauna is formed by the species of East Palaearctic and Palearchaearctic distribution. In Khanka Lake Palearchaearctic species are prevail. Mayflies from Khanka Lake basin included in eight and from Khanka Lake in five ecological complexes. Species inhabiting both ritral and potamal zones are widely represented in lake basin. In basin of Razdolnaya River the residents of ritral or potamal, and of both these zones are represented eqiually. Similarity between mayfly local faunas of Khanka Lake basin and the Razdolnaya, Ussuri and Lower Amur rivers is shown. High similarity between faunas of Khanka Lake, Razdolnaya and Lower Amur rivers with account of unique species, which distribution is limited in Primorye by Khanka Lake, and in Khabarovskii Krai by the downstream of Amur River presents close relations between watercourses of these basins. Annotated list of mayfly species of Palearchaearctic type of distribution is presented.
