The author found syntopic specimens of Euscorpius italicus and E. tergestinus inside and nearby an abandoned fortress in Verona Province, Veneto, Italy. This discovery highlights a possibility of coexistence of congeneric species not only in the same territory, as already observed, but also in the same habitat and microhabitat, bringing some interesting questions about interspecific competition within the genus Euscorpius.
