potto are in the dentition. Sarmiento notes, however, that captive specimens may develop abnormalities in the teeth and that some dental characters Schwartz uses are quite variable, sometimes even from one side of the same individual to another. The third upper molar (M3) is more reduced in the false potto than in any other prosimian, according to Schwartz, but Leon notes that western pottos also have a relatively small M3. The third upper premolar (P3) is also reduced, resembling the condition in the fork-marked lemurs (Phaner). Stump writes that small P3s are also common in western pottos, although the false potto's P3 is shaped differently. Groves notes that P1 is quite long, another point of similarity with the fork-marked lemurs. The lower premolars are compressed laterally in Pseudopotto, the cusps on the cheekteeth are higher, and the cristid obliqua (a crest connected to the protoconid cusp) is at a relatively buccal position (in the direction of the cheeks). In AMZ 6698, skull length is 59.30 mm (2.335 in) and length of the right humerus is 57.65 mm (2.27 in). Distribution and status According to records in the Anthropological Institute and Museum, AMZ 6698, the holotype, is from "Equatorial Africa", and AMZ-AS 1730 is from the "Cameroons". According to mammalogist Ronald Nowak, these designations imply that the latter came either from modern Cameroon or far eastern Nigeria (British Cameroons) and the former from Cameroon or a neighboring state. In 1999, Simon Bearder claimed, citing a personal communication by C. Wild, that Pseudopotto had been seen in the wild and in 2001, ornithologist Christopher Bowden noted the occurrence of Pseudopotto on Mount Kupe in Cameroon, also citing C. Wild. However, the IUCN Red List notes that while sightings of the false potto at 820 to 940 m (2690 to 3080 ft) on Mount Kupe had been reported, surveys had failed to confirm its occurrence there, though pottos, some with long tails, had been found. The false potto was formerly included under the potto in the Red List, however, , it is treated as a synonym of the Central African potto (Perodictitus edwardsi) due to the evidence that it is a distinct species being considered insufficient. The American Society of Mammalogists instead synonymizes it with the West African potto (P. potto).
