Tidarren is a genus of tangle-web spiders first described by Ralph Vary Chamberlin & Wilton Ivie in 1934.
Males are much smaller than females, and they amputate one of their palps before maturation, entering their adult life with only one palp. 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. It may also be done because only one palp is needed.
