%X In a study on Fanniidae biogeography, Dominguez & Roig-Ju ent (2011) argued that the family had a Pangeic origin, Late Jurassic/early Cretaceous (~146 Ma). However, recent literature on Diptera supports that Schizophora radiation occurred during Cenozoic. Fanniidae is a widespread taxon and it was interpreted under the maximum vicariance paradigm; the consequence was an analysis with no alternative hypothesis, but Pangeic origin. We verified that Fanniidae historical narrative was incongruent with the Gondwana sequential break-up. A second analysis, assuming the Fanniidae origin during early Paleocene (65 Ma), showed congruence with recent geological events and with the Muscidae diversification, a closely related Muscoidea family. Our hypothesis suggests that the Fanniidae originated in Paleogene and they were affected by few events of vicariance and several expansions during Cenozoic. En un estudio sobre biogeograf赤a de Fanniidae, Dom赤nguez & Roig-Ju ent (2011) argumentaron que la familia era de origen Pangeico, Jur芍sico superior/Cret芍ceo inferior (~146 Ma). Sin embargo, literatura reciente sobre Diptera, confirma que la radiaci車n de Schizophora ocurri車 durante el Cenozoico. Fanniidae es un tax車n ampliamente distribuido y fue interpretado bajo el paradigma de m芍xima vicarianza; la consecuencia, fue un an芍lisis sin hip車tesis alternativas, pero de origen pangeico. Nosotros verificamos que la narrativa hist車rica de Fanniidae es incongruente con la quiebra secuencial de Gondwana. Un segundo an芍lisis, asumiendo el origen de Fanniidae durante el Paleoceno inferior (65 Ma), mostr車 congruencia con eventos geol車gicos recientes y con la diversificaci車n de Muscidae, una familia de Muscoidea pr車ximamente relacionada. Nuestra hip車tesis sugiere que Fanniidae se origin車 en el Pale車geno y fueron afectados por pocos eventos de vicarianza y muchas expansiones durante el Cenozoico.
