political terminology question

Someone I work with is trying to figure out the generic term for a female political leader. He claims that there definitely is such a term but he can’t remember it. So what I’m looking for is a word that means “female political leader” that isn’t just a feminine form of a gender neutral term like president. I’ve tried searching the internet but my google searches aren’t pulling up anything usefull. Can anyone help me out here?

A female President is a President. A female Prime Minister is a Prime Minister.

“President” and “Prime Minister” ARE generic terms. There’s no need for a feminine version of those terms.

I don’t suppose your friend is seeking a term like “matriarch” (which is a female ruler, not necessarily a political leader).
