genus_authority = Chamberlin & Ivie,1934 "Tidarren" is a genus of spiders. The males are much smaller than females.
The males of this genus amputate one of their palps before maturation and enter their adult life with one palp only, probably to increase mobility, because the palps are really large compared to their tiny size.
In the Yemeni species "
Tidarren argo ", the remaining palp is then torn off by the female. Spider males use their palp to transfer semen into the female. The separated palp remains attached to the female's epigynum for about four hours and apparently continues to function independently. In the meantime the female feeds on the palpless male.Distribution
"Tidarren" species occur in Africa, and in Middle and South America.
