Abstract - A new Dimorphoreicheia Magrini, Fancello & Leo, 2002 from Central-West Sardinia (Coleoptera, Carabidae, Scaritinae) - A new taxon - Dimorphoreicheia quadrisetosa n. sp. - is described from Mount Monti Ferru (Cuglieri, Oristano), the type locality of the syntopic Typhloreicheia jucunda (Holdhaus, 1924). The new species, small and slender, looks like the geographically distant Dimorphoreicheia relicta Magrini, 2004 from Mount Gonare (Nuoro), rather than the closer Dimorphoreicheia vannii Magrini, Fancello & Leo, 2002 from Sedilo (Oristano). It is easy to differentiate the new species from the other two already known of the genus, on the basis of the characters of the aedeagus, and the number of bristles on the pronotal disc: four instead of two; further, the pronotum is much wider at base. A key to the three species of the genus is present.
