Taxonomy
Originally described as Galago alleni by Waterhouse (1838), the species was placed in a separate genus, Sciurocheirus by Gray in 1863. The species was split into three taxa, alleni, cameronensis, and gabonensis by Eisentraut (1973) and Groves (1989) 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).

Physical description
Bioko Allen's bushbaby has a head-body length of 20–28 cm with a 23–30 cm tail and weighs 300–410 g.
