Messor ibericus vit autour de la Méditerranée, a des reines plus petites et diffère par de petits détails des antennes, et une étude de 2025 parue dans Nature a montré que ses reines clonent des mâles de Messor structor et ont besoin de leur sperme pour produire des ouvrières : toutes ses ouvrières sont donc des hybrides.
