Mirinae is the largest subfamily and its endemism becomes evident at the tribal leveland below. Mirines of the tribe Restheniini are found throughout America, with most of the diversity confined tothe Neotropics. Prepops Reuter is the largest genus in Restheniini with 198 described species and its geographicalrange is similar to that of the tribe. The study of the distribution and areas of endemism in Miridae are scarceand non-existent for Prepops. We analyzed all the geographic records of Prepops (707 records for 181 species) inorder to identify diversity patterns and areas of endemism, using network analysis. Locality data were assignedusing museum specimens and geographic records in the literature. Additionally we used spatial data to proposehabitat preferences and geoclimatic variables important for each group of co-occurring species. The resultsindicate high species richness in subtropical regions, while the tropical belt and high latitudes appear impoverished.The Neotropical region contains 86% of the species, and the Nearctic about 11 % (but with larger speciesranges); the Andean region is sparingly represented. Twenty-three areas of endemism (and two diads), formedby 2 or more endemic species, are distributed in the Nearctic (3), Mexican Transition Zone and Caribbean subregion(5), South American Transition Zone and Amazonian, Chacoan and Paranaense subregions (15). Overlapbetween some of the areas indicates regions with high species richness and complex history. The lack of recordsfrom the Andean region (except for P. nigrus in Southern Patagonia) and dominance of strictly Neotropical species(86 %) supports the hypothesis of a Neotropical origin for the tribe Restheniini. The general arrangement ofthe units of co-occurrence of Prepops species shows a close correlation with known biogeographic regions andsubregions. Broad physiographic characteristics most commonly associated with Prepops geographical recordsare, in order of importance: broad leaf forests (wet and dry), grasslands and xeric habitats. Rev. Biol.
