Subtribe Oiocerina Pilgrim, 1934

Diagnosis.—Small to medium sized bovids with homonymously twisted horncores inserted above the orbits and occasionally extended over the short or absent pedicles; well−developed lateral notch present on the crown of the cornual process (i.e., the pedicle–horncore contact), and continuous with a basolateral sulcus on the horncore variously dividing the lateral surface of the latter into an anterior and a posterior portion; horncores parallel to subparallel in their proximal part, and moderately to strongly divergent distally; postcornual groove positioned laterally or absent; supraorbital foramina located within pits; temporal ridges reduced or absent; basioccipital relatively short and usually bearing a medial groove, as well as closely spaced anterior tuberosities.
