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 molecular data support the view that Sparisoma originated approximately 14-35 million years ago, probably in the tropical western Atlantic, off Brazil; there have been at least four discrete bouts of cladogenesis within the genus, with the most recent one involving four events in both the east and the west Atlantic and across the Atlantic.

TL;DR: Previous hypotheses regarding the relationships among the American grouper species and the allied genera were evaluated by examination of mitochondrial DNA sequences of the 16S ribosomal DNA region, and maximum-parsimony criteria and neighbor-joining analysis dispute the monophyly of the American Epinephelus species.
