Distribution

Cosmopolitan species of tropical and subtropical origin; in Europe, it has been introduced and established in Croatia, France, Italy, Malta, Portugal (Azores), Spain (including the Canary Islands), Russia and Ukraine ( Mifsud and Knížek 2009, Knížek 2011). The data provided here represent the first record of the species in continental Portugal (Fig. 6 ).

Notes

All specimens were collected using black multi-funnel traps set up at 5 m above the ground and baited with a multi-lure blend of longhorn beetle pheromones ( Fan et al. 2019), ethanol and alpha-pinene.

Hosts

An extremely polyphagous species with several hundred host plants, belonging to 81 different families. The most represented hosts are: Anacardiaceae (9 species), Cucurbitaceae (7 species), Euphorbiaceae (14 species), Fabaceae (72 species), Fagaceae (7 species), Juglandaceae (8 species), Malvaceae (24 species), Moraceae (25 species) and Sapindaceae (9 species) ( Browne 1961, Schedl 1962, Bright and Skidmore 1997, Bright and Skidmore 2002, Atkinson 2022).

Identification remarks

Kambestad et al. (2019) have shown that under the name Hypothenemus eruditus exists a complex of cryptic species whose identity is not yet defined. Since it is not clear which of these taxa is really present on the European territory, in the present contribution, we refer to Hypothenemus eruditus in sensu lato.
