  A pseudoscorpion clinging to a cave salamander: phoresy or failed predation? Abstract Pseudoscorpions are well known for phoretic associations with arthropods, but interactions with amphibians are rarely documented. Here we report a pseudoscorpion attached to the left palpebral region of an adult male Italian cave salamander, Speleomantes italicus , observed during a visual survey in a karst cave in Tuscany, Italy. The pseudoscorpion, assigned on the basis of visible morphology and locality to Chthonius cf. elongatus , was grasping a minute cutaneous fold on the lower margin of the left upper eyelid with one chela while the salamander moved slowly over the rock surface. No handling was performed and the initial contact between the two animals was not observed. The event therefore cannot be interpreted unambiguously, but may represent opportunistic phoresy or defensive attachment following a failed predation attempt. To our knowledge, this is the first published observation of a ...

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

Abstract

The spider fauna of Tbilisi was systematically documented in the early 2000s, 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.
