The eastern dwarf galagos are a group of five species of strepsirrhine primates of the family Galagidae, native to East Africa. They were formerly classified in the genus Galagoides but have been moved to their own genus, Paragalago, based on genetic evidence, and supported by differences in vocalizations and morphology. [1] The three western/Congolian species remain in Galagoides.

The two genera are not sister taxa and thus apparently evolved their small sizes and some morphological similarities via parallel evolution, although members of the eastern group tend to be larger. They are separated by the East African Rift. Paragalago is actually sister to the genus of 'lesser galagos', Galago , which are similar in size. [1] There is limited sympatry between Paragalago and the much more widely distributed Galago. Paragalago members range in mass from 60 to 250 g, considered small to medium-sized among galagids. [1]

All five species have been evaluated by the IUCN. P. orinus is considered to be vulnerable, P. rondoensis to be endangered, P. zanzibaricus is listed as near threatened, while P. cocos and P. granti are of least concern.

The Taita mountain dwarf galago, found in the Taita Hills, is unclassified. [2] Based on vocalizations, it may be the Kenya coast galago. These dwarf galagos are present in very small forest fragments and are in immediate danger of extinction.

Erythrocebus is a genus of Old World monkey. All three species in this genus are found in Africa, and are known as patas monkeys. While previously considered a monotypic genus containing just E. patas, a 2017 review argued that, based on morphological evidence and heavy geographic separation between taxa, E. patas should be split back into distinct species as recognised in the 19th century.

Lesser bushbabies, or lesser galagos, are strepsirrhine primates of the genus Galago. They are classified, along with the other bushbaby and galago genera in the family Galagidae. They are probably the most numerous primate in Africa, and can be found in every large forest on the continent, inhabiting forested areas, savannas, riverine bush and open woodlands.

It lives in an area reported in 2012 to be less than 100 square kilometers and is threatened by habitat loss due to logging. While it was discovered in the 1950s, the Rondo dwarf galago was deemed data deficient until 1996. In 1996, the Rondo dwarf galago was fully described as a species. It is now listed as one of "The World's 25 Most Endangered Primates."

<span class="mw-page-title-main">Angolan dwarf galago</span> Species of mammal

The Angolan dwarf galago is a species of dwarf galago native to Angola, and was named after western Angolan Kumbira Forest. Though 36 individuals of the Angolan dwarf galago were identified in September 2013, it was declared as a new species in 2017, and is now the nineteenth species of galago to be identified. Its call, described as "A loud chirping crescendo of longer notes, followed by a fading twitter", was enough to separate it as a new species, without any genetic identification, due to its uniqueness.
