Patterns of description of new species of beetles from Mexico between 2000-2020 were analyzed. We based our study on the Zoological Record of Web of Science^™. We found 1,867 species in 61 families described in 759 papers published in scientific journals from all over the world. Scarabaeidae is the family with the most species described (352) in the last two decades, followed by Staphylinidae (198), Curculionidae (196), Cleridae (176), and Cerambycidae (175). Most species of Mexican beetle were described in Zootaxa, Coleopterists Bulletin, Insecta Mundi, Dugesiana, and Zookeys. We also provided comments on issues to consider when Zoological Record is used for analysis such as in this study.
