TL;DR: A new genus of lacertid for the lineage including A. vauereselli and the new Itombwe species is described, highlighting the conservation importance of the Albertine Rift, especially the Itombw Plateau, a unique region that is severely threatened by unchecked deforestation, mining and poaching.
TL;DR: The Equatorial African group of lacertids comprises nine species which share a number of derived features and appear to constitute a holophyletic assemblage and Adolfus jacksoni has most features in common with the hypothetical ancestor of the group, while Holaspis guentheri and the species of Gastropholis are the most derived forms.
Abstract: The Equatorial African group of lacertids comprises nine species which share a number of derived features and appear to constitute a holophyletic assemblage. Revision of the group using morphological characters analyzed by parsimony and compatibility methods results in the following taxonomic changes: Lacerta jacksoni = Adolfus jacksoni, Lacerta echinata = Gastropholis echinata, Bedriagaia tropidopholis = Gastropholis tropidopholis, Bedriagaia moreavi = Gastropholis prasina, the latter species being validated and removed from the synonymy of Gastropholis vittata. Adolfus jacksoni has most features in common with the hypothetical ancestor of the group, while Holaspis guentheri and the species of Gastropholis are the most derived forms. Geographical variation in Adolfus alleni is described and what is known of the ecology of the Equatorial group summarized. Most are forest dwellers with the majority of the more primitive forms living on tree boles and among litter and timber on the forest floor (Adolfus jac...
