Cenozoic Mammals of Africa

The lorisiformes are a group of strepsirrhine primates, comprising the extant galagos and lorisids, that are included together in the superfamily Lorisoidea. They share with other crown strepsirrhines the possession of a specialized tooth comb, comprising the lower canines and incisors, reduced upper incisors with a broad central diastema, and a toilet claw on the second pedal digit. Molecular, karyological, and anatomical studies confirm that galagos and lorisids are monophyletic with respect to lemuriforms from Madagascar. Earlier molecular studies produced contradictory results concerning the monophyly of lorisids and galagids, respectively. The galagos are included together in a single family, the Galagidae, restricted to sub-Saharan Africa. The later Tertiary fossil record of Lorisiformes is quite poor, being restricted to material from the middle to late Miocene of the Siwalik Group of northern Pakistan and to Miocene and Plio-Pleistocene localities in Africa.
