During a survey of the gnaphosid spider fauna of Iran, two interesting species of Drassodes Westring 1851 were collected. Drassodes marusiki sp. n. (♂♀, Isfahan Province, central Iran) is described as new to science, and its relationship with the closely related D. bifidus Kovblyuk & Seyyar 2009 (Turkey) is discussed, and Drassodes robatus Roewer 1961, which was originally described from Afghanistan, is recorded for the fauna of Iran for the first time; a redescription for its male and the first description for its female are provided.
