Clypeogethes elongatus (Rosenhauer, 1856) in Sardinia (Coleoptera: Nitidulidae, Meligethinae)

Clypeogethes elongatus (Rosenhauer, 1856) is a pollen-beetle occurring in SW Mediterranean areas, from Southern Iberian Peninsula to most of the North Africa; in Italy, this uncommon species was thus far known only from the Island of Pantelleria (southern Sicily). Recent researches in S Sardinia allowed to find a small relic population of this species in Cagliari (San Michele hill), where it is cer-tainly associated with early-flowering Brassicaceae, on chalk-based rocks.
