A faunistic database on the spiders of the Caucasus
The content of the German journal ‘Arachnologische Mitteilungen’ is available as PDF articles. However, the four most current journals are restricted to members of the ARAGES or subscribers of this journal respectively.
Even though the journal focusses on the arachnofauna of Central Europe, some articles are related to Caucasian spiders.

"... 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)
