Notes. Having not found any Sardinian specimens in the many studied collections, Penati and Vienna (2002) had considered this species, previously only generically mentioned from Sardinia in the literature, as absent from the island. A more in-depth study of the MSNG collections and of the Baudi di Selve collection (CFB) brought to light numerous specimens collected on the island in the second half of the nineteenth century and the beginning of the twentieth century, confirming the correctness of the literature records. The recent records demonstrate the ongoing presence of the species in Sardinia. Baudi di Selve, in his handwritten catalogue of the collection, ascribed the authorship of the variety delatum to Gené, probably based on an in litteris description; however, this variety has always been ascribed to Baudi himself, as he was the first to use this name in a printed work ( Baudi di Selve 1864).
