Two specimens -one represented by a virtually complete skeleton and adult dentition and the other by skull, mandible, and mixed dentition- in the collections of the Anthropological Institute and Museum, University of Zurich-Irchel, that had been cataloged as Perodicticus potto do not possess the salient features of this prosimian primate. Although these specimens are cladistically lorisiform, and in some features are variably similar, especially to Arctocebus, Nycticebus, and Perodicticus, they do not share the suite of apomorphies that unites these extant lorisids plus the fourth genus, Loris, as a clade. The postcrania (preserved for one specimen) are primitive relative to those of lorisids in having a long tail and lacking a distinctly hooked ulnar styloid process. Both specimens are dentally primitive relative to lorisids in retaining a more buccally emplaced cristid obliqua and lacking deep hypoflexid notches on the lower molars, as well as in having relatively longer lower middle and last premolars. Nevertheless, these specimens appear to be more closely related to the lorisid clade than the more well-known lorisiform groups, the cheirogaleids and the galagids. In light of their dissimilarity to any other known lorisiform primate, a new genus and a new species are named to accommodate this previously unrecognized prosimian.
