The European forest angle spider ( Tegenaria silvestris , Syn . : Malthonica silvestris ) is a species from the genus of the angle spiders ( Tegenaria ) in the family of funnel spiders (Agelenidae).
features
The females are 6 to 9 millimeters long, the males 5 to 6 millimeters. The forest angle spider is thus a small species within the genera Malthonica and Tegenaria . The species is dark brown with contrasting light and dark spots. A light, almost reddish stripe stretches across the back of the abdomen, as in the rust-red angle spider . The legs are also provided with alternating light, reddish brown, and dark brown rings.
The forest angle spider can be distinguished from related species by the drawing of the sternum (breast plate on the ventral side of the foreleg). In the forest angle spider, the black sternum has a light stripe that is narrowed in two places. On each side of the strip there are three bright points, separated from it.
habitat
Contrary to what its name suggests, the forest angle spider does not only occur in forests. The rare species is almost always found in the entrance area of caves in its range, so it is troglophilous . However, unlike other rock-dwelling spiders, it does not occur in houses.
In dry deciduous and coniferous forests , especially in mountainous areas, it can be found close to the ground, also on stony ruderal sites and scree slopes , less often on the edges of forests , rarely in cultivated biotopes . In a suitable habitat, it spins its funnel web under tree trunks and dead wood as well as in tree hollows. It is associated with the widespread and frequent Lepthypantes pallidus , Trochosa terricola and Histopona torpida and the wolf spider Pardosa lugubris (forest edges, hedges , forests).
nomenclature
The forest angle spider was called Tegenaria silvestris until 2005 and then renamed Malthonica silvestris . Angelo Bolzern (2007) and Marco Isaiah (2011) count the forest angle spider back to the genus Tegenaria . It can easily be confused with other species in the genus Tegenaria .
