Carabid species richness and phylogenetic diversity were evaluated in the four biogeographic provinces present in the state of Hidalgo, Mexico. Using a list of species and incorporating records obtained from a review of the Coleoptera Collection of the Autonomous University of the State of Hidalgo, 752 records were obtained, which included 138 species classified into six taxonomic categories. The provinces with the highest species richness are the Sierra Madre Oriental and the Chihuahuan Desert; those with the lowest species richness are the Transmexican Volcanic Belt and the Veracruzan province. The Chihuahuan Desert was the province with the greatest phylogenetic diversity, and the Sierra Madre Oriental the least diverse. This highlights the usefulness of complementary estimates in diversity analyses in regions with a variety of disparate biogeographical histories. [ABSTRACT FROM AUTHOR]
