TRIBE MACHAIRODONTINI GILL, 1872

Remarks: Most recent authors use Homotheriini to refer to the scimitar-toothed cat, including, e.g. Amphimachairodus, Homotherium, Lokotunjailurus Werdelin, 2003 Xenosmilus Martin et al., 2000, and sometimes Machairodus Kaup, 1833 (Turner & Antón, 1997; Werdelin et al., 2010). When Machairodus is included in this tribe, which is adopted here, the correct tribe name should then be Machairodontini Gill, 1872 . In addition to the abovementioned genera, and the new genus described below, some smaller-sized species, e.g. derived species of Paramachaerodus like P. maximiliani McKenna & Bell, 1997, have a potential affinity to this tribe.
