Textrix denticulata  (Olivier, 1789)
≤ 1900   1901-1979   1980-2005   2006 ≤
Description: Male similar to female in general appearance. Carapace dark brown with light median band. Head narrow and with steep sides, not unlike spiders of the Pardosa genus (Lycosidae). Abdomen dark brown with light horse-shoe shaped marking anteriorly. Further back on the abdomen this marking is broken in to a series of paired light spots. Between the spots and inside the horseshoe marking are vague, somewhat reddish chevrons due to less dense clothing of hairs, causing the ground colour of the abdomen to influence the colouration. Legs yellow-brown with dark annulations and rings of white hairs. Size: Female 7-8 mm; male 6-7 mm.

Genus: Textrix Sundevall, 1833. Characters of genus: The members of this genus have the posterior row of eyes strongly recurved with the medials larger than the laterals. The narrow head is clearly set off from the thorax. The species may resemble wolf spiders as they are sometimes seen running about in sunshine, but the long and segmented posterior spinners are very noticeable and give them away as funnel web weavers. There are two species in northern and central Europe, of which one occur in Denmark.

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.
