The analysis was carried out in three stages. First, a PAE was carried out to define a general regionalization scheme for the MTZ, identifying areas and microareas of endemism for the entire area. Then PAEs were undertaken for each province. Third, a PAE was carried out to determine the relationship between the provinces of the MTZ. The analysis of the entire MTZ resulted in four areas and 57 microareas of endemism, while in the independent analysis of each province, five areas and 67 microareas of endemism were obtained. Both analyses coincide basically in the location of the areas and microareas of endemism, which are subordinated to biogeographic units defined by different authors. In the consensus cladogram of the third stage of the analysis, the Transmexican Volcanic Belt (TVB) is the sister area to the Sierra Madre Occidental (SMOC); then, they are the sister area to the Sierra Madre Oriental (SMOR); and finally the previous provinces are united in a trichotomy with the Sierra Madre del Sur (SMS) and the Chiapas Highlands (CHIS). It is assumed that the differences found when comparing our results with different cladistic biogeographic studies of the MTZ reflect the complexity of the study area. Since the data used to perform the analyses are not uniform, and both geographical units and taxa are different, the comparison between different analyses is difficult.

The morphological and the combined matrices analyzed with TNT yielded a single most parsimonious cladogram that allows recognition of two main lineages within the Pantomorus-Naupactus complex in North and Central America. One is represented by the species formerly placed in Phacepholis and the Pantomorus species group II sensu Sharp, ranging along the Pacific coast of Central America and Mexico and reaching the Great Plains of North America in the United States, yet not occurring in South America. The other lineage is represented by the species of Naupactus and Pantomorus species group I, with closer relationships to the South American species of these genera. The Pantomorus group I includes the type species of the genus (P. albosignatus Boheman) wh...

Their evolution may have been driven by geological and environmental changes. Our main goals were to explain the biotic diversification of this tribe in South America and to test previous hypotheses on the relationships between distribution areas.LocationNeotropical South America.MethodsWe compiled geographical records for 165 species of South American Naupactini. We then applied a track analysis and a parsimony analysis of paralogy‐free subtrees to obtain generalized tracks and a general area cladogram, respectively.ResultsWe retrieved 11 generalized tracks that coincided broadly with biogeographical areas of Neotropical South America: Northern Venezuelan, Galápagos Islands, Ecuadorian, Yungas, Cerrado, Caatinga, Puna+Pacific coastal deserts, Chacoan, Atlantic+Parana forests, Monte and Pampean. The single general area cladogram obtained showed the following topology: ((Northern Venezuelan–Ecuadorian) (G...
