Male Miqo'te - they have less population than females in general. Much less. Tip from Lodestone and Encyclopedia: Territoriality causes many of them to lead solitary lives, and males in particular shy from contact with others. For reasons yet unclear, female Miqo'te vastly outnumber males, a unique trait among Eorzea's races.
If we speak about Moon tribe, males there are even more rare than males in Sun clan.
Elves: Duskwight tribe is hardly represented at all. I can recall only one NPC from Lancer 1-30 level story. Why? Because they prefer to live in forest caves and caverns, avoiding cities. As for Wildwood tribe, they were pretty good represented in Ishgard. In Machinist 50-60 Story line there was a mention that in Ishgard they have a tradition, where women leave all their duties after marriage, so I assume that's the main reason why we do not see Elezen women in quests a lot.
Auri, I would say, were represented kind of equally, though not all NPC were in MSQ. But if we will recall exactly important NPC, we will have two females and two males in Azim Steppe and one (kind of two) females and one male in underwater village. Also Yugiri and some NPC in side quests, plus Auri from job quests, including DRK, WAR, NIN, WHM story lines, plus Alexander story line, etc. They are represented in their homelands as well because they are rarety outside of this and also not threatened well everywhere.
For Roes I have hard time to say, why we don't see a lot of them in MSQ. I don't see any reason for them to be really rare. Still, we did have some decent amount of them in Limsa quests, where at least Sea Wolves mainly live (Wiki mentions 17 notable Sea Wolves. Not that bad, actually. They are seem to be mostly males, though, and this is a puzzle for me).
