Nicolas,
Vipera ebneri only occurs on Talysh mountains (Azerbaijan) Elbruz mountains (Iran), "south" of Caspian sea.
Vipera eriwanensis (also formerly ssp. of ursinii) occurs in Armenia and adjacent Turkey (and Iran?).
The only other "ursinii" would be lotievi, but now included into renardi (V. r. lotievi).
Beside dinniki, the only other small viper occuring in mountain Georgia is Vipera darevskii, which looks very similar to dinniki, although only grey morphs are known.
All these vipers are very hard to determine!
Seems to be impossible by pictures only!
At least, from the picture, there is no pronounced canthus rostralis (a sharp edge of snout from eye to eye) visible, which would point to V. darevskii !?
