''Bugtilemur'' is an extinct genus of Strepsirhine

primate Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including huma ...

, complicating the picture of the early evolution of lemurs by suggesting that lemurs originated in Asia. Described from a few teeth, the specimen possesses a lower canine that, according to Marivaux et al., confirms the presence of the strepsirrhine-specific

toothcomb A toothcomb (also tooth comb or dental comb) is a dental structure found in some mammals, comprising a group of front teeth arranged in a manner that facilitates grooming, similar to a hair comb. The toothcomb occurs in lemuriform primates ( ...

Malagasy genus and its toothcomb was shorter and broader. More recently, the structure and general presence of the toothcomb in ''Bugtilemur'' has been questioned, as well as many other dental features, suggesting that it is most likely an adapiform. The adapiform nature of ''Bugtilemur'' was confirmed in a 2016 cladistic analysis that recovered it in the family Ekgmowechashalidae, which is more consistent with the lemur fossil record.
