Xylocopa (Koptortosoma) aestuans (Linnaeus, 1758)

Distribution. First recorded for Europe by Flaminio et al. (2023) from Sicily, Italy. The record of this species in Witt (2022) was actually X. virginica (L.) (see the correction of Witt & Westrich 2024). It is currently unclear whether it is established in Europe. Outside Europe the species is found in Southeast Asia including Java, Malaysia, and Singapore eastwards to Lombok.
