– Seine-Maritime, Le Havre, in the harbour, N 49.48070°, E 0.14384°, 11.IX.2023, Lindgren funnel trap baited with a multipheromone blend of cerambycids implemented with plant volatiles, 1 ex., INRAE-URZF leg. ( LNEF-ONF). Idem , 08.VIII.2014, on wood packaging material imported from Sri Lanka GoogleMaps , 1 ex., PEC76 leg.( ANSES). Since its first finding in Mions ( Rhône), on January 29, 2014, by the SRAL Rhône-Alpes in pallet wood coming from Indonesia ( Brustel & Aberlenc, 2014) , this species is now regularly intercepted in France.

Status in France. – Only intercepted.

Geographical distribution. – Native to tropical and subtropical areas of Asia, it was introduced to Europe in France, Germany, Great Britain, Greece, Italy, Malta, Poland, Russia, Spain, Switzerland and Ukraine (Borowski, 2007; Brustel & Aberlenc, 2014; Chittaro & Sanchez, 2019; Lykidis et al., 2016; Nardi & Mifsud, 2015; Ruzzier et al., 2023; Savoldelli & Regalin, 2009) where it does not seem to have established. It was also introduced in tropical and subtropical areas of Africa, Oceania, and the Americas where it appears established (Wilstermann & Schrader, 2019). It is also considered introduced to Japan (Iwata & Nakano, 2006). In that respect, this species has become cosmopolitan.

Remarks. – This species presents a low phytosanitary risk in Europe where it does not yet appear to have been established. However, in Ukraine and Moldova it is on the list of quarantine pests (Wilstermann & Schrader, 2019). In Italy, it was able to do its complete cycle in buildings and cause notable damage to all the pallet wood stocked (Savoldelli & Regalin, 2009). It is polyphagous and infests the sap wood of dry dead/felled trees including wooden packaging. Due to its low damage potential for living plants, S. unidentatum does not pose any phytosanitary risk for EU Member States (Wilstermann & Schrader, 2019). This species is mainly introduced into Europe with packaging, pallet, or construction wood. If the damage does not concern living trees, it can sometimes be significant on timber and wooden objects, sometimes cultural ( Lykidis et al., 2016).
