In lemur society are the males or females in power

I hope this helps:Primate Factsheets: Ring-tailed lemur (Lemur catta) Behavior

I just recently got to watch some lemurs at the zoo. They are wonderful to watch. They sit with their legs stretched out in front of them like people on the beach. There was a lemur of another species they let hang out with them and even curled up with it. They are very social.
