(Going by people important enough to have voice actors...)
Female Elezen: Alisaie, Icehart
Female Highlanders: Minfillia is half (her upper half
), but Highlander counts as Hyur, and we have plenty of those
As for the guy from CT, he is important, but...
In spite of taking a lead role in a story with more than a few main cast members, G'raha is a bait-and-switch who can't ever show up again without a literal miracle, written off just short of becoming counted as part of the recurring cast. We may never even hear his name again. I'm pretty sure they were actually counting on players expecting otherwise to increase the impact of that final twist. That he did exist may even become an excuse if they decide not to make any more important male Miqo'te.
Yeah.
So while you could argue that there is a respectable male/female balance in the main cast in spite of racial disparities, it's only male Miqo'te who have this far remained excluded. And male Keepers especially have it rough anywhere they show up. And Yugiri, well, it's more that she's the first of her kind and already more important than any male Miqo'te in-game.
I admit I'm splitting more than a few hairs, but still.
