Distribution of the harlequin beetle, Acrocinus longimanus (Linnaeus, 1758) (Coleoptera: Cerambycidae: Lamiinae: Acrocinini), is not well known in Mexico. Using MaxEnt and statistical analysis, the distribution was characterized and degree of association with environmental variables, biogeographic provinces, altitude, and vegetation types were determined. A. longimanus specimens were sought in scientific collections, records in publications, and open-access resources. In total, 93 records were obtained, of which eight were new state records for Mexico. The species probably could occur in 20 states of Mexico. Temperature and precipitation were the most important environmental variables for creation of a distribution map. Provinces of greatest importance for distribution of the species were the Pacific Coasts, Gulf, and Petén. Altitude and vegetation type were key to distribution of the species. Knowing actual distribution of species through potential distribution models (MaxEnt) is important for understanding insect interactions and associations in ecosystems, as well as recognizing important areas to conserve.

Acrocinus longimanus (Linnaeus, 1758) (Coleoptera: Cerambycidae: Lamiinae: Acrocinini) presentaba poco conocimiento sobre su distribución en México. Gracias a las herramientas como MaxEnt, se puede tener una percepción sobre su distribución, además con estos modelos se puede determinar el grado de asociación con variables abióticas. El objetivo del estudio fue conocer la distribución potencial de A. longimanus, se determinó que las variables ambientales como temperatura, y precipitación, al igual que la altitud (msnm) son clave para la distribución de A. longimanus en México.
