Confirmation of Metatrichoniscoides leydigii (Weber, 1880) in Belgium, 60 years after discovery (Isopoda: Trichoniscidae)

The woodlouse Metatrichoniscoides leydigii (Weber, 1880) was first recorded from Belgium in 1954. However, the collected individuals were all females incapacitating identification to species level. More intensive surveys in the autumn of 2015 revealed many new recordings with the discovery of the first male individuals. Finally, the species could be confirmed for Belgium after more than 60 years after its first discovery. The species seems to be quite common on clay soils in the north-western part of the country.
