Abstract
The genus Folsomides Stach, 1922 is represented by nine species in the Ibero-balearic fauna, one of which is new to the science. Folsomides mediterraneus n. sp. is found in Northern Spain (Navarra and Zaragoza) and Central Spain (Madrid). The new species is related to the Folsomides angularis (Axelson, 1905) group and it is easily distinguishable from other species by the chaetotaxy of microsensilla. A key for the identification of Ibero-balearic species of Folsomides is given.References
