The spread of two alien species of assassin bugs, Zelus renardii Kolenati, 1857 and Nagusta goedelii (Kolenati, 1857) (Hemiptera: Heteroptera: Reduviidae) in Sardinia (Italy)

The distribution of the two alien species, Zelus renardii Kolenati, 1857 and Nagusta goedelii (Kolenati, 1857) in Sardinia is summarized and commented, with the addition of some new records, including the first populations of Z. renardii in the northern and central-west of the island (Sassari and Oristano) and the first finding of N. goedelii in central-east Sardinia (Nuoro). Further considerations on the possible pathways of the two taxa are made, and the current distribution of the two species in Italy is also discussed.
