A faunistic database on the spiders of the Caucasus
Umit Kebapci just sent me a link to an article and a citation relating to spiders of NE Turkey (click on citation):
Bayram, A. & Varol, M. I. (2003): On Poecilochroa variana, recently collected in Turkey for the first time (Araneae: Gnaphosidae). Zoology in the Middle East. (30): 101-104

"... a thorough collecting of Arachnids in Transcaucasia would yield a magnificent prey because, namely in spiders, an astonishing richness in both individuals and species made itself noticeable." L. Koch (1878)
