Resumo: | Sphecodes majalis, a new bee species for the Netherlands (Hymenoptera: Apidae)  A population of Sphecodes majalis was found on a limestone grassland near Maastricht  (Limburg). On several occasions more than 10 female and several male specimen were observed.  Sphecodes majalis is a parasite of Lasioglossum pallens, which was recorded for the first time in the  Netherlands in 1997. Since then L. pallens has become well established in the southern part of  the province of Limburg. At the locality where S. majalis was found, L. pallens occurs in large  numbers. In April many dozens of males swarm along the woodland edges. The less conspicuous  and solitary females mainly nest in dense Festuca rubra swards with a thick litter layer,  rather than in the open Mesobromion plant community. At these nesting sites the largest  numbers of S. majalis were observed.  As S. majalis was recently found in nearby Belgium, its appearance in the Netherlands was  expected. Yet the Belgian-Dutch occurrence seems to be situated way outside the known  distribution area, the nearest sites being located in southern Germany and western Switzerland.  In well-studied Germany S. majalis is long known from one locality in Bavaria without any sign  of expansion. All Swiss records however are made since 1970. It is therefore hypothesized that  the recent expansion has followed a south-western route, i.e. through France, where the knowledge  of the distribution of bees is rather patchy.
