Callilepis nocturna (Linnaeus, 1758), Xysticus acerbus Thorell, 1872 en Pardosa proxima (C.L. Koch, 1874) gevonden bij Heerlen (Aranaea, Gnaphosidae, Thomisidae, Lycosidae)

Callilepis nocturna (Linnaeus, 1758), Xysticus acerbus Thorell, 1872, and Pardosa proxima (C.L. Koch, 1874) are rarely collected in the Netherlands. In 2003 and 2005, these species were observed in the most southern part of the Netherlands, close to the city of Heerlen. All three species were caught on a large roadside verge of the highway A76 with a species-rich and flowery hay-meadow vegetation (Arrhenatheretum elatioris). Two males of Xysticus acerbus were found here in the spring of 2003. One male of Callilepis nocturna was found in 2005 and this paper presents the first description of a finding place for this species in the Netherlands in at least 126 years. In 2005 also one male was found of Pardosa proxima, a lycosid spider with its main distribution in southern Europe. All the previous finding places in the Netherlands of the three species are given, and some other new localities for Xysticus acerbus and Pardosa proxima.
