Spiders in a Growing City: New Country and Regional Records of Spiders (Araneae) from Tbilisi, Georgia

The spider fauna of Tbilisi was systematically documented in the early 2000 s, when 252 species were recorded from the city and its surroundings. Despite a rapid urban expansion over the past two decades, subsequent studies have increased this number to 371 species. In the present study, we provide the first Georgian records of Tolokonniella stigmatisata (Menge, 1869) (Lathyidae) and Scotargus pilosus Simon, 1913 (Linyphiidae), and record Drassodes serratichelis (Roewer, 1928) (Gnaphosidae) in the Caucasus region for the first time, all based on specimens collected in Tbilisi.
