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 Anisandrus maiche (Kurentzov, 1941) and Cnestus mutilatus (Blandford, 1894) or the click beetle Monocrepidius posticus (Eschscholtz, 1829)), while for others (e.g. the scarab beetle Archophileurus spinosus Dechambre, 2006), data confirm their establishment and highlight a possible expansion phase. The false powderpost beetles Ptilineurus marmoratus (Reitter, 1877) and the longhorn beetle Xylotrechus chinensis (Chevrolat, 1852) are two new additions to the Italian fauna, while the establishment of the monotomid beetle Monotoma americana Aubé 1837 is confirmed.

In the perspective of an increasingly globalised world in which goods and people move at an ever-increasing speed, maintaining a high level of attention towards non-native and invasive species is fundamental (
Methods for capturing specimens have been quite diverse and included direct collection (e.g. litter/organic debris sifting, beating tray, sweeping net;
Eastern Palearctic species, established in European Russia (
The data confirm that the species is widely distributed and relatively common in northern Italy, Lombardy in particular. Although Anisandrus maiche is a modestly polyphagous species on broadleaf trees (
Ambrosiophilus atratus is an ambrosia beetle native to the Eastern Palearctic now established in France, Italy and Slovenia (
Ambrosiophilus atratus is a highly polyphagous species, capable of developing in both hardwoods and conifers (
The finding of the specimen in Molfetta, more than 170 km from the area of the first recording (see
Species of Nearctic and Neotropical distribution (
Species of phytosanitary relevance (e.g.
Species native to the Oriental and Eastern Palearctic Regions, established in North America (
Cnestus mutilatus is a somewhat polyphagous species (
Species native to China, Japan, Korea and Taiwan, recorded multiple times in Austria, France, Germany, Great Britain, Italy, Poland, Sweden, Switzerland and the Netherlands; observations indicate established populations only in France (
The recollection of the single specimen in Ronchi dei Legionari, in nature, suggests the existence of an established population in the area. However, given the close vicinity of the Monfalcone port, a well-known port of entry for non-native species (
Species native to the Neotropics and now established in both the Nearctic and Western Palearctic (
Species included in the CABI Invasive Species Compendium; to date, there is no information on the real economic or environmental impact of this non-native species (
North American species (
The finding of additional specimens confirms the establishment of this species in the Italian territory, as the occurrence of this taxon was so far limited to the only vague indication given in
Taxon native to China, Indonesia, Japan and introduced in Germany, Sweden and USA (
The two records, which occurred in different regions and in nature, clearly indicate the establishment of the species in the Italian territory. Ptilineurus marmoratus is a negligible pest in the countries of origin, where it has been recorded damaging stored grains (
Species widely distributed in southeast China and Japan (
Psacothea hilaris is facing a substantial expansion phase in northern Italy (
Species of Oriental origin and now established in Asia, North, Central and South America, Africa (including Madagascar) and Oceania (
Sinoxylon unidentatum has been recorded multiple times in Europe (
Species of North American origin and established in Central and South America, Europe, the Oriental Region and in the Near East (
Stelidota geminata is an relevant pest of strawberries in North America (
Species of Nearctic origin, established both in Italy and Spain (
Species of Eastern Palearctic origin, introduced in Europe and North America (
In Italy, Trichoferus campestris was first detected in Piacenza in 2000 (
Species native to East Asia, introduced in Europe (
In Europe, Xylotrechus chinensis was first officially reported in 2013 in Catalonia (
The faunistic records here presented further demonstrated how Italy, due to its climatic and environmental peculiarities, is rather predisposed to host and foster the establishment of non-native beetles; in confirmation, it is sufficient to note that most of the species that have arrived in recent decades are all undergoing a substantial range expansion. It is also interesting to note that species new to the Italian fauna are already present at the European level, indicating a general homogenisation of the non-native fauna due to species natural spreading and unintentional human-mediated transport amongst EU countries. The latter could be the case for the recent arrival of Xylotrechus chinensis, whose Italian population may originate from infested areas in Spain or France, rather than a random introduction from countries of origin (a hypothesis that requires further investigation). Given the enormous diversity of species and adaptations that characterise Coleoptera, maintaining a national level of monitoring and data collection would not be possible without the continued support of the non-professional entomological community, as well as from citizen-science initiatives. In particular, especially for species that are more conspicuous and identifiable by photography, at least in the first instance, careful monitoring of social networks can help to collect totally unexpected observations.
