In 2024, this upload with a picture of genitals included, was made on iNaturalist, showing Euborellia arcanum (=Anisolabella ryukyuensis according to molecular data from Petr Kočárek) on Mauritius:

It has been found at a hotel and some specimens are now in Germany, Bavaria, where the uploader is trying to breed them. If he succeeds, he'll send me some specimens for storage.

2009, a morphologically similar earig was observed on Réunion:

An exact identification by picture is not possible, but it is likely to be the same species too or another related species, most probably Anisolabella sp.

Possible ways of introduction could have been tourists from East Asia, North America or Europe.
