Molecular phylogenetic analysis of archival tissue reveals the origin of a disjunct southern African Palaearctic weevil radiation
[Aim] We test three alternative hypotheses for the disjunct Mediterranean–southern African distribution of endophagous weevils within the genera Rhinusa and Gymnetron (Coleoptera: Curculionidae): (1) a Palaearctic origin with dispersal to southern Africa; (2) a southern African origin with dispersal...

| Summary: | [Aim] We test three alternative hypotheses for the disjunct Mediterranean–southern African distribution of endophagous weevils within the genera Rhinusa and Gymnetron (Coleoptera: Curculionidae): (1) a Palaearctic origin with dispersal to southern Africa; (2) a southern African origin with dispersal to the Palaearctic; and (3) a widespread ancestral distribution fragmented by vicariance. Divergence times are estimated to provide an approximate temporal framework for the evolution of the group and to evaluate potential palaeogeographical scenarios. |
