24, see text Tidarren is a genus of tangle-web spiders first described by Ralph Vary Chamberlin & Wilton Ivie in 1934.

[3] Though it is uncertain why they do this, it may be done to increase mobility, as the palps are disproportionately large compared to the size of the body.

Females of the Yemeni species T. argo tear off the single remaining palp before feeding on males.

The palp remains attached to the female's epigynum for about four hours, continuing to function despite being separated from the male's body.

[4] As of April 2019[update] it contains twenty-four species:[1] "Tidarren".
