<jats:p><jats:italic>Stator limbatus</jats:italic> is a phytophagous beetle native to warm regions of North and Central America, feeding on Fabaceae seeds and one of the most polyphagous species within the subfamily Bruchinae, here reported for the first time in Europe and on new hosts. Adult beetles emerged from <jats:italic>Acacia</jats:italic> spp. seeds collected in the islands of Corsica (France), and Sardinia (Italy). The wide presence in Sardinia and Corsica supports the hypothesis that this alien species was introduced several years ago. In both islands, <jats:italic>S. limbatus</jats:italic> emerged from <jats:italic>Acacia mearnsii</jats:italic> seeds, with infestation rates of up to 74.2 and 90.8% in 2019 and 2020, respectively. This seed beetle also emerged from two previously unreported host species, <jats:italic>Acacia saligna</jats:italic> and <jats:italic>A. pycnantha</jats:italic>, showing highest infestation rates of 4.0 and 95.1%, respectively. Both <jats:italic>Acacia</jats:italic> species are reported as new host associations with <jats:italic>S. limbatus</jats:italic>. Overall, seed infestation rates recorded in 2019 and 2020 indicate that <jats:italic>S. limbatus</jats:italic> is well established and that Mediterranean bioclimatic conditions are suitable for its population increase in size. This study lays the foundations for further research on known and potential host species and the spread and distribution of <jats:italic>S. limbatus</jats:italic> in Europe.</jats:p>
