Genus Hyainailouros Biedermann, 1863

Type species: Hyainailouros sulzeri Biedermann, 1863 ; Middle Miocene (MN 6) of Veltheim, Switzerland .

Remarks.—A revised synonymy was provided by Lewis and Morlo (2010), but following Morlo et al. (2007) we additionally recognize Megistotherium Savage, 1973 , as a junior synonym of Hyainailouros . In this contribution, we focus on the African members of this genus.

Our recognition of Megistotherium as a junior synonym of Hyainailouros ( Morlo et al. 2007) contrasts with the view of Borths et al. (2016) and Borths and Stevens (2019), who view the genus as the sister taxon to Leakitherium Savage, 1965 . The material from Buluk does not contribute new evidence toward resolving this issue.
