First italian record of Nemausus sordidatus (Stål, 1858) collected in southern Sicily: accidental introduction or expansion of range? (Hemiptera Heteroptera Alydidae)

The broad-headed bug Nemausus sordidatus (Stål, 1858) is reported as a new record for Italian
fauna. Several specimens have been observed on and collected from its host plant, Acacia saligna
(Labill.) H.L.Wendl. (Fabaceae), in the vicinities of Niscemi (Caltanissetta) in Sicily since 2004. The
biology and distribution of the species are briefly discussed together with the possible origin of its
presence in Sicily.
