N2 - The genus Strongwellsea (Entomophthorales) has a unique pathobiology. Infected adult dipteran hosts develop a large hole in their abdomens, through which conidia are actively discharged while the hosts are still alive. We analyzed the IST II region of Strongwellsea from 29 infected hosts representing 15 dipteran species from Anthomyiidae, Fanniidae, Muscidae, and Scathophagidae. Each genotype was found on only one host species or a few closely related host species. Strongwellsea genotypes infecting flies from Anthomyiidae represented a monophyletic lineage, including the species Strongwellsea castrans, while genotypes infecting Muscidae were very diverse and clustered at different places. All three host species from Fanniidae were infected with the same Strongwellsea genotype, namely the species Strongwellsea magna. It appears that members of the genus Strongwellsea are strongly adapted to their host species and have co-evolved.
