 In a series of potto ( Perodicticus potto ) skeletons in the collections of the Anthropological Institute and Museum of the University of Zurich at Irchel , anthropologist Jeffrey H. Schwartz recognized two specimens with traits he believed distinct from all pottos , and in 1996 he used these two specimens to describe a new genus and species of primate , Pseudopotto martini . The generic name , Pseudopotto , combines the element pseudo- ( Greek for " false " ) with " potto " , referring to superficial similarities between the new form and the potto . The specific name , martini , honors primatologist Robert D. Martin . The exact provenance of the two specimens is unknown , and one is represented by a complete skeleton ( but no skin ) and the other by a skull only . Schwartz placed both specimens in a single species , but noted that further study might indicate that the two represent distinct species . He thought the relationships of the new form were unknown and difficult to assess and did not assign it to any family , but provisionally placed it closest to the family Lorisidae , together with the potto , the angwantibos , and the lorises . The discovery , published in the Anthropological Papers of the American Museum of Natural History , was featured in Scientific American and Science ; the Science account noted that Schwartz thought Pseudopotto may represent a new family of primates .
