Mythimna (Morphopoliana) languida (Walker, 1858) (= consanguis auct. nec. Guenée, 1852) is recorded from South Tyrol (northern Italy) and, for the second time after Parenzan & Scalercio (1996), from southern Italy. This species can easily be confused with some other Noctuid moths. Adult moths (both sexes) and genitalia are figured. M. languida is an originally tropical species with a wide distribution area from Africa over southern Asia to Australia, but recorded in Europe just recently from Greece, Crete, Malta and southern Italy. These European records are probably due to immigration, but the species may also become sedentary in the most southern parts of Europe. It is discussed, whether such an immigration must be considered as a new phenomenon or whether the species has just been overlooked.
