ABSTRACT. Four species of Incestophantes Tanasevitch, 1992 are described from the mountains of Middle Asia: I. barskaun sp.n. (♂) and I. susamyrtau sp.n. (♂) from Kyrgyzstan; I. ramit sp.n. (♂, ♀) from Tajikistan; and I. kaltakul sp.n. (♂) from Uzbekistan. The unknown male of I. hissaricus (Tanasevitch, 1989) comb.n. ex Lepthyphantes Menge, 1866 is described for the first time. A diagnosis of the genus Incestophantes is refined, and its species list is updated. Taking into account the new data, the Holarctic genus Incestophantes is known to contain 28 species. The mountains of South Siberia and Middle Asia are the most species‑rich regions for Incestophantes, with eleven and five congeners, respectively.
