摘要：In this study we establish the biogeographical affinities of the Scarabaeoidea dung beetle fauna in the drysoutheast of the Mexican Plateau and analyze species diversity and how it changes with site, soil and vegetation type.Beetles were systematically captured in 6 windows in the region between Perote, Veracruz and El Seco, Puebla. A totalof 9 species and 960 beetles belonging to Scarabaeinae, Aphodiinae and Trogidae were captured. Canthon humectushumectus and Phanaeus quadridens were found in greater abundance in cattle pastures. Trox plicatus is the only speciescaptured in the badlands. The beetle fauna of this landscape is poor owing to a combination of circumstances, mainlythe soil, recent volcanic activity and limited food availability. The results obtained are compared with those of 2 otherdry landscapes in central Mexico (Metztitlán and Tehuacán). Our landscape shares 50% of its species with Metztitlánand 37.5% with Tehuacán. The species shared between all 3 landscapes are Canthon (B.) puncticollis, Onthophaguslecontei and Labarrus pseudolividus. The fauna was characteristic of the southern Mexican Plateau, but poorer in boththe number of species and individuals; some species—expected from a biogeographic perspective—were missing.Key words: copronecrophagous beetles, Mexican High Plateau, Scarabaeinae, Aphodiinae, geographic distribution
