- Xylosandrus crassiusculus (Motschulsky) (Figs. 3E, 3F) Distribution. Native to Asia, X. crassiusculus is a cosmopolitan species, present on all continents. In Europe, it was detected for the first time in Italy in 2003 in Tuscany (Pennacchio et al. 2003) and then spread across the country in the regions of Liguria, Veneto, Friuli Venezia Giulia, Lazio, Campania and Piedmont (Gallego et al. 2017). In France the species was repeatedly intercepted in the port of Le Havre, Seine-Maritime, on wooden packaging materials from China, and then recorded in southeastern France in 2014 (Nageleisen et al. 2015), in Switzerland in 2015 (Daubrée 2016), in Spain in 2016 in the Valencia region (Gallego et al. 2017), and finally in Slovenia in 2017 (Kavčič 2018). The distribution of X. crassiusculus in France was relatively restricted until 2017, confined to east of the Alpes-Maritimes, mainly in the town of Nice in the Mont-Boron forest. At the margins of this infestation, the species was trapped in four municipalities of the same district. Despite the eradication attempts set up in 2014 for the Nice infestation, the species is now established and clearly expanding in France (Daubrée 2016). Since 2018, two new breeding populations have been discovered in south-west of France, far from the first introduction sites (Roques et al. 2019). As with Xylosandrus germanus (Nageleisen et al. 2015), X. crassiusculus seems able to quickly colonize new areas and could spread over a large part of France in only few decades.
