﻿AbstractThe taxonomy of the Iranian species of the dysderid spider genusDysderaLatreille, 1804 is revised. Currently, the only species of this genus known from Iran isD.pocockiDunin, 1985, albeit on the basis of a doubtful record. The following 14 species are described as new to science in this paper:D.achaemenessp. nov.(♀; Fars),D.bakhtiarisp. nov.(♂; Chaharmahal & Bakhtiari),D.damavandicasp. nov.(♂; Mazandaran),D.genoensissp. nov.(♂♀; Hormozgan),D.hormuzensissp. nov.(♀; Hormozgan),D.iranicasp. nov.(♂♀; Fars, Hormozgan),D.isfahanicasp. nov.(♂♀; Isfahan),D.mazerunisp. nov.(♀; Mazandaran),D.medessp. nov.(♂; Tehran),D.persicasp. nov.(♂♀; Golestan, Mazandaran),D.sagartiasp. nov.(♂♀; Tehran),D.tapuriasp. nov.(♂♀; Mazandaran),D.verkanasp. nov.(♂; Golestan), andD.xerxesisp. nov.(♂; Bushehr). Distribution records of all species are mapped. Also, the taxonomy ofMisturaPetrunkevitch, 1971 andSegistriitesStraus, 1967, two fossil genera currently considered inDysderidae, is discussed and the latter is transferred toSegestriidae.
