Textrix denticulata, the toothed weaver, is a funnel web spider of the family Agelenidae found in much of Europe. It was described by the French entomologist Guillaume-Antoine Olivier in 1789. An older name coined by Martini & Goeze in 1778, Aranea cruciger, has been declared a nomen oblitum, allowing Olivier's later name to stand.
The male Textrix denticulata is similar to the female in general appearance. The carapace is dark brown with a light median band. The head is narrow, with steep sides, not unlike wolf spiders of the genus Pardosa. The abdomen is dark brown with a light horse-shoe shaped marking towards the anterior which breaks down into a series of light spots towards the posterior. There are vague, somewhat reddish chevrons due to the relatively thinner coating of hairs between the horseshoe mark and the posterior spotting which causes the background colour of the abdomen to be visible. The legs are yellow-brown with dark annulations and rings of white hairs. The body length of the female is 7–8 mm, that of the slightly smaller male 6–7 mm.
