Eastern gorilla
Grauer's gorillas and mountain gorillas were previously thought to be two of the three subspecies of one single species, the gorilla ("Gorilla gorilla"). However, genetic research has shown that the two eastern subspecies are far more closely related than the western subspecies: the western lowland gorilla ("G. gorilla gorilla"), which justified the separate classification. The two eastern subspecies are now classified as "G. beringei".
Brown greater galago
The brown greater galago ("Otolemur crassicaudatus"), also known as the large-eared greater galago, is a nocturnal primate, the largest in the family of galagos. As opposed to smaller galago species it would climb, walk or run rather than leap.
