I edited the map from Sagona's book

 I edited the map from Sagona's book. Added two other cultures that are mentioned but not marked in the map. 

Samtavro in Shida Kartli region of Georgia. It is in the North of Kur river. Later it correspond to historic Iberia.

Khojaly-Gadabay. Laneri et al. thinks that it was related to Lchashen culture. Later it correspond to Artsakh and Utik' provinces of Armenia. 

The borders of Colchian culture were exaggerated in that map. From Abkhazia further north starts other Iron Age culture known as Meotic which is usually linked to NWC people. Later the region was known as Colchis. 

But the land of Aia (Kolchoi) mentioned in Argonauts was almost certainly not in Colchian culture place but further south, west of Rize, and east of Synop.

Lchashen culture correspond to Etiuni tribal confederation. This culture was present in Kars, Igdir but it's pottery was rare in Erzurum. Occasionally it is also found in Agri region of Turkey. Later it correspond to Ayrarat and Gugark provinces of Armenia.

Kaiakent-Charachoi was in North East Caucasus with some presence in North Azerbaijan. It almost certainly correspond to NEC people. Their migration to south in Iron Age will create the Caucasian Albania.

Talysh or Talysh - Mugham correspond to various Iron Age tribes who were living there. Remarkably some of their pottery was found as far as in southern parts of Karabakh. 

And finally the Koban culture. Their ethnicity is unknown. But they almost certainly played an important role in the ethnogenesis of Alans. Which formed as a mixture of Scythians and Koban people.

Some scholars proposed a link between them and Tauri people living in Crimea. Some scholars want to link it with with Nakh people but that is quite unlikely.
