Comments. Dysdera hungarica Kulczyński, 1897 is one of the most widely distributed species of Dysderidae , known to range from Austria to the Caucasus. There are over 25 records of it in the Caucasus, and all of them are situated along the Caucasus Major Mountain range.

There are three subspecies of D. hungarica present in the Caucasus.According to Dunin (1992b), the nominative subspecies occurs in the Northern Caucasus and the southern part of Azerbaijan. It is relatively smaller than the other subspecies, with a carapace length of 2.5 (vs. 4 and 5 in the other subspecies), and is found at lower elevations ranging from 300 to 900 m.

Dysdera hungarica atra Mcheidze, 1979 , on the other hand, lacks proper illustrations and is limited to the eastern part of the Caucasus Major. It inhabits higher elevations, ranging from 700 to 2400 m. Another subspecies, Dysdera hungarica subalpina Dunin, 1992 , is known only from North Ossetia and is reported at elevations from 1000 to 2500 m. These three subspecies can also be distinguished by differences in their spination patterns. The subspecies-level identification of the present material is primarily on the basis of the collection localities of the specimens.

Distribution. Caucasus Major: northern Azerbaijan and eastern Georgia.
