We report the first population of Aedes (Fredwardsius) vittatus in continental America, detected in Yucatan, Mexico. Phylogenetic analysis clustered the Mexican sequence with Caribbean lineages (posterior probability 0.8-0.9), suggesting introduction via the Caribbean. Given its arbovirus competence, urgent inclusion in surveillance programs is warranted.
