| description | <p>The Afrotropical members of the dung beetle genus <em>Catharsius</em> Hope, 1837 (Coleoptera: Scarabaeidae) are investigated and systematically revised. Morphological phylogenetic analyses of 138 taxa and molecular phylogenetic analyses of a subset of 15 taxa are conducted. The results indicate the paraphyly of the genus with regard the monotypic genus <em>Copridaspidus</em> Boucomont, 1920 and <em>Catharsius</em> is split into five species-groups. Biogeographical ancestral state reconstruction indicates that the woodlands to the south of the Congo Basin are the location of origin of the genus, with several independent colonisations of Asia. Dispersal-vicariance analysis shows that many dispersal events rather than vicariance events are responsible for the current geographical distribution of this genus. A new tribe, Catharsiini, is erected to include the genera <em>Catharsius</em> and <em>Metacatharsius</em>. Two genera, <em>Copridaspidus</em> and <em>Catharsiocopris</em> Balthasar, 1967, are synonymised with <em>Catharsius</em>. In total, 128 African species are recognised, of which 39 species are new to science. Name-bearing type specimens of 98 of 106 described taxa were studied with four neotypes and 48 lectotypes designated. Six taxa are raised from synonymy, eleven new synonymies are established and one species is placed as incertae sedis. The <em>C. molossus</em> species group of 29 species is fully revised with the re-description of 25 species and description of four new species. For each species of the <em>C. molossus</em> species group, images of both sexes and of the male genitalia are figured, along with distribution maps. A key to the five species-groups as well as a key to species of the <em>C. molossus</em> group are provided and a gazetteer of all African localities of <em>Catharsius</em> is compiled.</p> |
