Historical biogeographic analysis of the family Fanniidae (Díptera: Calyptratae), with special reference to the austral species of the genus Fannia (Diptera: Fanniidae) using dispersal-vicariance analysis

The purpose of this study was to achieve a hypothesis explaining the biogeographical history of the family Fanniidae, especially that of the species from Patagonia, the Neotropics, Australia, and New Zealand. We used "dispersal-vicariance analysis" (DIVA), an event-based parsimony method,...
