how to export citations with italicised (e.g.) species names?


as mentioned in the subject I`ve large folders with citations of species descriptions following the rules the names being italicised - however, when I export them (with any style) I get citations without any italics…

What do I do wrong - what is the trick?

Thanks in advance

Are you saying they are in your record with correct italicization but are exported without any italics?  That is not my experience.  (see attached).  

Or that they are being imported without italicization even thought the database record is correctly italicized?

But many databases don’t reflect the title italics.
