Chorotype. Palaearctic.

Ecology. A widespread and common species in various habitats, more frequent in mountainous areas. Bivoltine in parts of its range.

Notes. In the absence of material, the discovery of Dilophus sardous sp. nov. brings some doubt about the occurrence of the closely related D. femoratus in Sardinia (which however remains possible). The specific identity of the species of this group may only be confirmed by the study of male genitalic characters or by detailed molecular studies. Accordingly, D. femoratus is provisorily deleted from the list of Sardinian species, pending the examination of possible relevant material.
