Eustigmaeus is one of the largest genera in this family and currently contains 102 species (Fan 2005; Fan & Zhang 2004, 2005; Doġan 2005; Faraji et al. 2007; Cheng & Fan 2008). In Turkey, 20 species are known (Doġan 2007; Doġan et al. 2011). In this paper one species, Eustigmaeus varius sp. nov., is described as new. Another species, Eustigmaeus lacuna (Summers) , originally found in U.S.A., is newly recorded for the Turkish fauna and redescribed. In addition, 12 known species are recorded from new localities.
