Phylogenies revealed a well-supported monophyletic Gyraulus clade with a broad distribution across Eastern Eurasia and the presence of several internal geographic lineages. On the two insular regions, a power-law model best described the relationship between phylogenetic and geographic distances, suggesting limited dispersal and diversification through infrequent OD events. Divergence time estimations suggested that Gyraulus diversification originated after the late Miocene. The Oriental region of Eurasia was the most frequent source of dispersal. Across all trees, 6–8 OD events were estimated throughout the entire period, primarily on oceanic islands, with a single exception on a continental island at high latitudes. OD frequently originated from non-adjacent regions, in contrast to other dispersal events. Longitudinal dispersal was more frequent than latitudinal dispersal, and geographic lineages exhibited widespread longitudinal distributions.
