Arctosa personata? => Arctosa sp.
« am: 2018-09-16 20:54:26 »
Rep. of Georgia, Gori, 15.09.2016.
Unfortunately this is the only photo (specimen was no collected).
Can anyone confirm the determination?

Not A.personata, it is not even recorded in Georgia

The thing that it's not recorded in Georgia means almost nothing.
Btw, it's recorded from neighbouring Azerbaijan.

Interestingly, personata is given in WSC as Western Mediterranean, and all taxonomic references are from that region. Wondering how reliable the references from the Eastern side of the "hole" are. But on the other hand, it fits habitually well.

These eastern records of A. personata in Turkey and adjacent countrieds need to be verified, because all came from more or less unreliable faunistic works and there is a large distribution gap covering the Balkan region, Greece, Bugaria etc., while the species is relatively common e.g. on the Iberian Peninsula.  There are currently several poorly known Arctosa-species in the region, e.g. Arctosa ravida, simoni, lagodechiensis, and most probably some are still to be described. It is possible that this is a eastern sibling species of A. personata, while it seems, at least currently, biogeographically inplausible that A. personata has such a disjunct distribution in Europe.

I do not see any possibility to determine this animal seriously.

Thnak you Simeon and Tobias for your reasonable opinions.
Yes, I was thinking the same (about reliability of references from Caucasus and possible sibling species).
