In this paper, we provide new taxonomic and faunistic data on the dysderid spider genera Dysdera Latreille, 1804 and Harpactea Bristowe, 1939 based on material collected in the Caucasus region. We identified a total of seventeen species, of which D. atabekia sp. n. (♂♀; Goychay and Ismayilli districts, Azerbaijan), H. abasgiana sp. n. (♂♀; Republic of Abkhazia, Georgia), and H. dunini sp. n. (♂; Zagatala district, Azerbaijan) are described as new to science and their distributions are mapped. Furthermore, three new records are provided: D. daghestanica Dunin, 1991 from Krasnodar Krai, D. concinna L. Koch, 1878 from Iran, and D. mazini Dunin, 1991 from Azerbaijan. By examining the type series of Harpactea caucasia (Kulczyński, 1895), we found that at least a part of Dunin's records of this species refer to H. abasgiana sp. n., and his figures of this species in fact refer to an undescribed species. Brief notes are provided on the northernmost distribution limits of Dysderidae.
