The taxa of the new genus Coelosynapha gen. n. in a dataset of 6500 sequences of Nordic Sciaroidea clearly separates the two species in distinct BINs. Locally in the Nordic Region, the genus Palaeodocosia Meunier, 1904 show highest similarity with Coelosynapha, while species of both Synapha and Coelosia are more distant.
