Family Dysderidae C.L. Koch, 1837 are distributed in West Palearctic. Several species of the genus Dysdera Latreille, 1804 were recorded from Iran. A new species belonging to D. ninnii species group was found during our investigation on Darab spider fauna. The bulb has simple crest in this species group. In our new species, Dysdera sp. bulb is small. Tegulum is almost large, its length is greater than width, and bell shaped. Psembolus is shorter than tegulum. Median crest and apex are triangular. Posterior apophysis is claw-shaped with triangular growth on anterior side. Stylusis bent, short and weak.
