The squirrel galagos are a group of four species of strepsirrhine primates. They are classified in the genus Sciurocheirus of the family Galagidae.1

Originally a single species was described, Galago alleni, by Waterhouse (1838), and the species was placed in a separate genus, Sciurocheirus by Gray in 1863.2 While some listings still included them in Galago,3 the species was split into three taxa, alleni, cameronensis, and gabonensis by Eisentraut (1973) and Groves (1989)4 which were then later elevated to species status by Groves (2001) as S. alleni, S. cameronensis, and S. gabonensis and followed by Groves (2005) and Nekaris (2013).32 The IUCN and American Society of Mammalogists both list S. cameronensis as a subspecies of S. alleni (as listed below). In 2013, another species, S. makandensis was described.56
