The Toronto Zoo’s meerkats are kept in the African Rainforest Pavilion, something which I knew was biogeographically inaccurate when I first looked at their website at age 8.
Though you could argue that it’s not a geographically-themed area anymore, the Toledo Zoo’s Tembo Trail used to be called the African Savanna, and when it first opened with the new name it solely displayed African species. However, it is now home to North American river otters, grizzly bears, yaks, Bactrian camels, reindeer, Tasmanian devils, and an Indian rhinoceros alongside African elephants, common hippopotamus, and meerkats.
Detroit Zoo has ring-tailed lemurs in their Asian Forest, Japanese Macaques in their African Grasslands, and tree kangaroos in their American Grasslands. Though to be fair the geographic theming of all these areas is pretty loose.
