TL;DR: The present phylogenetic hypothesis suggests that the Alcelaphini are monophyletic; that the genera Parmularius and Damaliscus share a recent common ancestry; and that the extant Hunter's hartebeest should not be removed from DamalISCus into a separate genus Beatragus as several authors have done.
Abstract: Cladistic principles are applied to a group of antelope species, three-quarters of which are extinct. Only cranial and mandibular characters are used. The present phylogenetic hypothesis suggests diat the Alcelaphini are monophyletic; that the genera Parmularius and Damaliscus share a recent common ancestry; and that die extant Hunter's hartebeest should not be removed from Damaliscus into a separate genus Beatragus as several authors have done. A re-evaluation is suggested of die systematic position of Lichtenstein's hartebeest, as being phylogenetically closer to me wildebeests, genus Connochaetes, than to the type species of the hartebeest genus Alcelaphus. Some problems arising in the application of cladistic principles to such a low ranking group, treating die fossil majority exactly equivalently with recent taxa, are discussed. Comments on recency of common ancestry as it affects hybridization potential in bovids, on speciation and extinction rates arise.

TL;DR: The Australopithecus-bearing sites of Koro Toro in central Chad yielded at least 9 species of bovids, most of which belong to genera found in North and/or East Africa, but three new species are named, probably an early offshoot from primitive Reduncines.
Abstract: The Australopithecus-bearing sites of Koro Toro in central Chad yielded at least 9 species of bovids (Ruminantia: Bovidae). They all belong to genera found in North and/or East Africa, but three new species are named. Kobus korotorensis n. sp. is quite distinct from East African species, and is probably an early offshoot from primitive Reduncines. Kobus tchadensis n. sp. is more like some East African forms. Parmularius pachyceras n. sp. should rather be compared with a North African species. This relative endemism hinders precise biochronological correlation, but the best fit is in the range 2.7 - 3.4 Ma. The lack of Tragelaphines, and an abundance of Reduncines, Alcelaphines and Antilopines definitely points towards an open environment, that was drier than most East African sites of this age.
