New records of non-native Coleoptera in Italy.

Abstract

In the last decades, climate change and globalisation have been exacerbating the introduction of non-native beetles worldwide. Due toits peculiar territory, climate and geographical position in the middle of the Mediterranean Basin, Italy is one of the European countries with the highest number of intercepted, adventive and established non-native beetles, some of which are invasive. In this perspective, producing new faunistic records and continuously updating reliable and easily accessible distributional data is a fundamental step in investigating and potentially preventing further species introduction. The aim of this contribution is to report and discuss new faunistic records of non-native Coleoptera in Italy. For some species, new records enlarge the previously-known distribution (e.g. the ambrosia beetles Anisandrusmaiche (Kurentzov, 1941) and Cnestusmutilatus (Blandford, 1894) or the click beetle Monocrepidiusposticus (Eschscholtz, 1829)), while for others (e.g. the scarab beetle Archophileurusspinosus Dechambre, 2006), data confirm their establishment and highlight a possible expansion phase. The false powderpost beetles Ptilineurusmarmoratus (Reitter, 1877) and the longhorn beetle Xylotrechuschinensis (Chevrolat, 1852) are two new additions to the Italian fauna, while the establishment of the monotomid beetle Monotomaamericana Aubé 1837 is confirmed.
