Our results demonstrate that specimens of this species have been collected in traps from August 2019 to November 2023 in three localities in Southeastern Spain (from Almería and Murcia provinces) and one locality in Western Mallorca (Table 1, Figure 1). The initial detection occurred in August 2019 in Aguadulce (Almería province), where two specimens were captured by light trap (Figure 2). Subsequent captures were made in the same locality during August and September 2020 using the same trapping method. In October 2021, a single specimen was captured in a light trap in Ribera de la Algaida (Almería province), a nearby locality located 5 km from the first site. In 2023, a trap baited with ethanol and alpha-pinene was installed in Aguadulce, resulting in the capture of two additional specimens, one in August and another in October. On the island of Mallorca, a single specimen was captured in October 2021 in a trapping campaign targeting the exotic Xylosandrus compactus. No further captures have been recorded in this location. In October 2022, seven specimens were captured in a trap dedicated to the early detection of exotic species, which was located adjacent to a biomass processing plant in Caravaca (Murcia province). This trap has remained active since 2021 and has not captured any further specimens of this species.
