I don't think women were considered to have magic potential in any ancient stories so there wouldn't actually be an example. But wizard and mage are basically synonyms: wizard being proto germanic in origin and mage being Persian in origin so any female mage is a female wizard.
There are examples of male witches, about 25 percent of the witches executed during historic witch hunts were men.

I haven't heard of female mages in traditional fiction or myth, either, though I also don't think it would be incorrect. There have been many magical female characters in traditional literature and myth, but they have not been called wizards (or mages). They have been mostly enchantresses, sorceresses and, yes, witches.
