De miljoenpoot Archiboreoiulus pallidus nieuw voor de fauna van Nederland (Myriapoda: Diplopoda)

The millipede Archiboreoiulus pallidus, new to the Dutch fauna (Myriapoda: Diplopoda) Some specimens of the millipede Archiboreoiulus pallidus (Brade-Birks, 1920) were found in April 1996 in ‘het Bovenste Bos’, a deciduous forest south of Epen, in the province of Limburg. Two weeks later, a visit was paid to the collection of the Plant Protection Service and this resulted in a second record of this species. This specimen was found in June 1977 in an agricultural field near Maastricht, about 15 km west of Epen (province of Limburg). This is the first record of A. pallidus for the Dutch fauna. This species is morphologically very similar to Blaniulus guttulatus. The most important characteristics in which A. pallidus differs from B. guttulatus are described and illustrated. A short introduction to the ecology of A. pallidus is given and the distribution in Europe is shown. With this new species, 47 millipedes are now known to occur in the Netherlands.
