The common stone slab spider or stone mouse spider ( Drassodes lapidosus ) is a spider from the family of flat-bellied spiders (Gnaphosidae) and is the largest and most common species of the genus stone slab spiders ( Drassodes ).
description
The common stone slab spider is relatively light, light brown to yellow-brown in color, only the chelicerae and the area around the eyes are darker. The size information about the animals varies between 6 mm and 18 mm. The male can reach up to 13 mm, the female 18 mm.
It can also bite people, the bite being harmless other than reddening the skin.
Distribution and occurrence
The common stone slab spider is widespread throughout the Palearctic and inhabits the plains up to the low mountain ranges in Central Europe and prefers dry habitats such as dunes, meadows, light forests, but also occurs in boggy areas. It is also occasionally found in buildings. It is mainly found in the litter layer directly on the ground. The subspecies Drassodes lapidosus bidens (Simon, 1878) has so far only been found in France.
Taxonomy and systematics
The common stone slab spider is the type of stone slab spider ( Drassodes ). Walckenaer described the species as Aranea lapidosa in 1802 . Westring established the genus of stone slab spiders in 1851.
The copper stone slab spider ( Drassodes cupreus ) (Blackwall, 1834) can not be sufficiently differentiated morphologically from the common stone slab spider. Therefore Ute Grimm did not include the copper stone slab spider in her study Die Gnaphosidae Mitteleuropas . Bolzern and Hänggi examined a number of specimens of both species in 2006 and found a large variability of the distinguishing features listed in the literature so far. These merge into one another in such a way that a clear distinction between the two types is not possible. The two arachnologists therefore suggested examining other features.
