Abstract: | The fauna of the family Scathophagidae of Yakutia, including 44 species of 15 genera, was studied. 23 species are recorded from the territory for the first time. The Arctic and subarctic zones of Yakutia have been still poorly studied, and additional species are found there. The scathophagid fauna of Yakutia was compared with the faunas of the neighboring regions using the dendrogram similarity method based on calculation of the Czekanowski–Sørensen coefficient. |
