Number: 446, Pages: 13 - 23
New data on the fauna of mayflies in the Anabar River basin are given. A total of eight species of Ephemeroptera have been identified in the fauna of North-Western Yakutia for the first time. Though the mayfly fauna in this region consists mainly of East Palaearctic species, the only seven of them are characterized by arctic-alpine distribution. In general, mayfly species richness of the studied subarctic and southern rivers of Yakutia is similar.
