The false potto is a lorisoid primate of uncertain taxonomic status found in Africa. Anthropologist Jeffrey H. Schwartz named it in 1996 as the only species of the genus Pseudopotto on the basis of two skeletal specimens of uncertain provenance that had previously been identified as pottos. Schwartz thought the false potto could represent a separate family, but other researchers have argued that the supposed distinguishing features of the animal do not actually distinguish it from the potto; specifically, the false potto shares several features with West African pottos. The false potto generally resembles a small potto, but according to Schwartz it differs in having a longer tail, shorter spines on its neck and chest vertebrae, a smaller, less complex spine on the second neck vertebra, an entepicondylar foramen (an opening in the humerus, or upper arm bone), a lacrimal fossa (a depression in the skull) that is located inside the eye socket, a smaller upper third premolar and molar, and higher-crowned cheekteeth. However, many of these traits are variable among pottos; for example, one researcher found entepicondylar foramina in almost half of the specimens in his sample of pottos.
