Hello!

I can’t understand to what genus it is correct to refer the butterfly, which is listed on this forum as _Favonius quercus_ (Linnaeus, 1758) Blauer Eichen-Zipfelfalter.  
Three names are used in different sources:

- _Favonius quercus_ (Linnaeus, 1758)
- _Quercusia quercus_ (Linnaeus, 1758)
- _Neozephyrus quercus_ (Linnaeus, 1758).  
As far as I understand, these names are synonyms (were relevant at some point in time), but which one is relevant now? From the literature I was able to understand that the species used to belong to the genus _Quercusia_ (Settele et al., 2008, page 29), but this genus is now included in the genus _Favonius_. However, the position of the genus _Neozephyrus_ is not clear to me. I am confused by this term from wikipedia

Link to wiki Favonius genus [https://en.wikipedia.org/wiki/Favonius\_(butterfly)](https://en.wikipedia.org/wiki/Favonius_(butterfly))  
_Favonius quercus_ (Linnaeus, 1758) is now _Neozephyrus quercus_ in North Africa, Europe and Asia Minor’

I understand that wikipedia is not a reliable source of information (moreover, articles about butterflies lack references to literature), but from my experience with butterfly taxonomy, everything that was written in wikipedia was eventually confirmed by other academic literature, but in _Neozephyrus quercus_ case I did not find any information.

Could you please explain to me the status of _Neozephyrus quercus_ and suggest a reliable source of information on this topic. Thank you.
