A male crowned lemur (right) grooms the dominant female (2nd pic)
Crowned lemurs exhibit a strict matriarchal social structure where the dominant female leads the troop. She holds exclusive priority access to the best food resources and sleeping spots. Males will even groom her and defer to her during foraging. --NIH website
Crowned lemur social groups typically consist of 5 to 6 individuals, which include multiple adult males and females. Dominance allows the matriarch to maintain her energy reserves, which are vital for nursing and rearing offspring. --Atlanta Zoo
So evidently these cuties (and cousins of ours) work like meerkats in terms of social hierarchy. I first learned about such watching the lovely, excellent Meerkat Manor documentary TV show. More than just about any other animal docu I've ever watched, it gave a frank, nuanced look at the daily lives of meerkats, to the point that it almost seemed like a soap opera at times.
The first season is available to watch for free, here:

Note: despite the two animals looking somewhat similar, lemurs belong to the Primate order, and mongooses to the Carnivoran order, specifically the Feliform (cat-shaped carnivores) suborder. The other major suborder in Carnivora is of course the Caniforms (dog-shaped carnivores).
Duke U. in N. Carolina runs a "lemur center" and put together a nice web intro here:
