The goldspotted oak borer Agrilus auroguttatus Schaeffer is an invasive pest of three Quercus species in southern California, U.S.A. As a native and potentially indigenous exotic species, its distribution and potential damage is largely unknown in Mexico. We used the maximum entropy algorithm to determine the bioclimatic variables that may explain the distribution of A. auroguttatus , as well as its interaction with the distribution of known hosts in Mexico. Our model calculated high suitability for A. auroguttatus in the biogeographical provinces of California, the northern and southern areas of Sierra Madre Occidental and the northwestern area of the Mexican Plateau; moderate suitability was projected in the Baja California, Sonora and Sierra Madre Occidental provinces. Potential distribution of A. auroguttatus was overlapping with native ranges of Quercus agrifolia , Quercus emoryi Torrey and Quercus hypoleucoides A. Camus. Precipitation of the coldest quarter (23.6%), isothermality (23.5%), precipitation seasonality (17.3%) and mean temperature of the coldest quarter (11.2%) contributed most to explaining its distribution in Mexico. The geographical interaction (i.e. the likelihood that the habitat would be suitable for coexistence) of A. auroguttatus with its hosts in Mexico was projected in the California province (46 382.60 km 2 , probably as an exotic species) and the northwestern areas of Mexican Plateau and Sierra Madre Occidental provinces (74 013.45 km 2 , probably as native). Determining the areas of environmental suitability for A. auroguttatus and its host distribution can focus ground surveys, contribute to management efforts and assist in the development of risk assessments for Mexico.
