“…In contrast to the Polleniidae as a whole, phylogenetic relationships within the genus Pollenia are better understood. Pollenia, especially the West Palearctic representatives, has been the subject of several revisionary works (Jacentkovskỳ, 1941(Jacentkovskỳ, , 1942Zumpt 1956;Lehrer 1963Lehrer , 1967Mihályi 1976;Rognes, 1987aRognes, , 1987bRognes, , 1988Rognes, , 1991bRognes, , 1992aRognes, , 1992bRognes, and 2010, which resulted in a species-group classification system as well as two comprehensive phylogenetic studies: one using morphological data (Rognes, 1992a) and most recently using molecular data (Szpila et al, 2022). The Pollenia species-group system, established for West Palearctic species, is based on 11 species-groups (composed of 1-9 species per group) based on shared morphology (summarized in Table 1), developed by Rognes across a series of revisions (Rognes, 1987a(Rognes, , 1987b(Rognes, , 1988(Rognes, , 1991b(Rognes, , 1992a(Rognes, , 1992b(Rognes, and 2010.…”
