Tegenaria parietina  (Fourcroy, 1785)
≤ 1900   1901-1979   1980-2005   2006 ≤
Description: Carapace dark brown with wide, light-coloured central and lateral bands. Margin with three dark-brown patches in each side. Older specimens may have less contrast between light and dark areas and sometimes even appear uniform grey partly due to dense clothing with light hairs. Sternum with three equal-sized patches opposite coxa I, II, and III, and with light median band, however these markings are usually absent in older specimens. This is a long-legged species with the length of legs almost five-times the body lenght in males, much less so in females. Legs light yellow-brown with darker annulations especially on the femora. Legs of older individuals often uniform brown. Abdomen with yellow-brown central band flanked by fairly large light pathes, and some smaller, dark ones. Sides of abdomen with smaller spots in the same colours. Abdomen of older specimens is lighter, sometimes uniform light brown with long, relatively thin hairs. Size: Female 11-20 mm; male 11-17 mm.

Genus: Tegenaria Latreille, 1804. Characters of genus: Head prominent, protruding. Thoracic part of carapace oval. Posterior row of eyes slightly procurved with the medials marginally smaller than laterals. Trapezium formed by medial eyes widest behind. Clypeus higher than twice the diameter of an anterior medial eye. Chelicerae strong with distinct lateral condyles. Labium longer than broad. Carapace and legs with coverage of plumose hairs, however only discernible as plumose at high magnification. Tibia and patella of legs I less than 1.5 times the length of the carapace. Abdomen oval, rather elongate with dense hairing usually with markings consisting of paired spots or chevrons. Posterior spinners long, more than twice the length of anteriors and widely separated. Males with similar markings as the females but slimmer and with relatively longer legs. Many species have characteristic markings on the sternum which may aid species identification. Members of Tegenaria possess a thick and short embolus originating from subapical part of the embolus (Guseinov et al. 2005). Formerly, the genus also included species with long, filamentous embolus originating basally or subbasally, but these species have been transferred to Malthonica (Guseinov et al. 2005).

Family: Agelenidae C. L. Koch, 1837 (Funnelweb Weavers). Characters of family: The agelenids belong to the group of entelegyne, ecribellate spider families having 8 eyes and 3 tarsal claws. The members of the family are characterized by the often very long, two-segmented posterior spinnerets, which taper toward the tip. The long spinners are visible even when the spiders are viewed from above. Another character for the family is the tarsal trichobothria, which are arranged, in a single row and increases in length toward the distal end. However, this character is shared with species that have been transferred to other genera in recent times. The carapace is characterized by often having the head (cephalic region) narrow and very clearly separated from the wider thoracic region. The eyes are equal sized and arranged in 2 rows of 4. The curvature of the posterior row of eyes is characteristic for some of the commoner European genera with some having this eye row recurved, straight or procurved. Sternum is heart-shaped and sometimes with markings which may aid species identification. Labium is as wide as long. Many species have long slender spinose legs and are capable of fast runs. The abdomen is oval and tapering posteriorly usually with species-specific colour patterns dorsally in various shades of brown and grey. Both the carapace and the abdomen are often densely covered by plumose hairs but this is only visible when using a lens or stereomicroscope. Epigyne is often large but the differences between related species sometimes small and a stereomicroscope is therefore required for proper identification. The male palp has a tibial apophysis. The shape of the apophysis is sometimes visible with a lens facilitating reliable identification of live males. In this respect it is an advantage to confine the specimen in a glass tube.
