A total of 2906 specimens of spiders were collected in the mountain valley of the Chomutovka brook in the Krušné hory Mts. between years 2000 and 2020. A total of 336 species were found. According to their abundance and degree of threat, 86 of them belong to significant and rare species. Most significant species are: Achaeridion conigerum, Brommella falcigera, Clubiona corticalis, Dipoena erythropus, Ero tuberculata, Gonatium hilare, Neon levis, Nusoncus nasutus, Pardosa sordidata, Phycosoma inornatum, Talavera thorelli a Theridion boesenbergi.
Spiders and pseudoscorpions on old pedunculate oaks (Quercus robur) with tree cavities were studied in a Central European floodplain (South Moravia, Czech Republic). Altogether 322 specimens from 47 spider taxa and 71 specimens of six pseudoscorpion species were collected during 2010 and 2011 from tree cavities using two methods. More specimens and species of spiders were obtained from flight interception traps and more specimens and species of pseudoscorpions were obtained from pitfall traps. Remarkable records represent typical cavity dwellers, i.e. the spider Midia midas (Simon, 1884), the pseudoscorpions Larca lata (Hansen, 1884) and Apocheiridium ferum (Simon, 1879), the latter occurs mostly under tree bark. Five arachnid species are listed in the Czech red list: Midia midas, Leptorchestes berolinensis (C. L. Koch, 1846), Dipoena erythropus (Simon, 1881), Larca lata and Dendrochernes cyrneus (L. Koch, 1873).
