Slovakia has more than one species of Villa, so you must see more than one. I am not going to purposely contradict someones opinion. If someone has told that you have Villa fasciata, then you should call it Villa fasciata.
I have learned that this genus is in need of a taxonomic revision. I am not a taxonomist. I do not know of any work being done on this genus.
I am aware of many attempts to make keys for Villa but I do not think that the keys are valid. I have found errors with hottentotta and modesta.
I think that many years of study are necessary for keys. Overlap and variability needs to be considered. Genitalia is not even mentioned in keys, much less dna study.
I like Bombyliidae, so I am trying to collect them for study. I live in Germany, so I have no experience with Villa outside of Germany.

The patagium is not a difference between male and female, so you have a different species of Villa.
Perhaps Villa modesta.
