Abstract

We analyzed species richness and ecogeographic patterns of Scarabaeinae (Coleoptera: Scarabaeidae) in Jalisco, Mexico. Occurrence data were compiled from digital databases, literature, and entomological collections, yielding 6,042 records for 86 species. A current richness model was generated using 100 km² grid cells, and species distribution models were constructed using MaxEnt to estimate potential richness. We also performed a principal component analysis based on 23 climatic variables to identify climatic affinity groups. Our results show that the areas with the highest current and potential richness are located in the Sierra Madre del Sur and the Pacific Coast provinces. We identified four main climatic groups that correspond to biogeographic provinces. These findings provide a comprehensive overview of Scarabaeinae diversity in Jalisco and highlight both sampling gaps and priority areas for future studies. The classification of species based on climatic affinities reveals a richness gradient and suggests distinct assemblage structures driven by environmental conditions.
