(Clerck, 1757) (Barn funnel weaver)
Male and female with similar in general appearance. Carapace greyish-brown with wide irregular bands in median line and sides. Abdomen light yellowish-brown with light grey indistinct markings forming vague chevrons at rear. The whole spider is clothed with long hairs, particurlarly the head region and the abdomen. Legs with faint annulations. Sternum dark with a narrow light median band flanked by three pairs of rather indistinct spots.
Almost exclusively in houses, rarely outdoors.
Known from most of Denmark but the species is much rarar than

is virtually cosmopolitan in distribution and occurs in houses in almost all climates.
Female 8-11 mm; male 6-9 mm.
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
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
(Guseinov et al. 2005).

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.
