Chorotype. East-Mediterranean; it replaces D. lineare in south-eastern Europe and Turkey ( Mayor 2007b). In the Balkan Peninsula the two species have been sometimes found together ( Croatia, northern Greece) (Liberti unpublished). Common in central and southern Italy, present in Sicily (probably not in North Africa). Sardinia appears to be the western limit of its distribution area.

Notes. Very similar species to D. lineare , from which it can be easily distinguished by the rounded elytral apex (not sharp as in D. lineare ). Rather common and widespread in Sardinia and already reported for the island by Bertolini (1899 –1904) and Porta (1929). Recorded from Nuoro ( MCSNG, in Mancini collection, det. Pic) by Gridelli (1950).
