Although Metasinopa fraasi is the only unambiguousspecies of the genus, the early Miocene species Metasinopa napaki from Uganda was originally assigned to Metasinopa by Savage, but was later moved to Paracynohyaenodon by vanValen, and is now assigned to the MioceneAnasinopa, as A. napaki. "Sinopa" ethiopica has been assigned to Metasinopa following Savage, but may be its own genus considering its youngeragerelative to M. fraasi.
