Myrmozercon brachiatus Berlese, 1903 (Mesostigmata: Laelapidae), originally described from Portici, Naples, Italy in 1903, is rediscovered for the first time in Iran from nests of Messor mediosanguineus Donisthorpe, using comparison with photographs of its holotype. These two female specimens were collected at Ben region, Chaharmahal va Bakhtiari Province, Iran. This new finding, far from the type locality, suggests a larger distribution of the species in the Palaearctic. A morphological description of these two specimens is provided.
