Arachnofauna přírodní rezervace Louky pod Kumstátem (Česká republika)

Abstrakt: In 2009, the arachnofauna of Louky pod Kumstátem Nature Reserve was studied. Spiders were collected between 18.iv.2009 and 25.x.2009 using pitfall traps. Land snail shells were collected in the winter of 2009–2010 to find hibernating spiders. In total 675 individuals (550 adult spiders) were collected, and identified as 69 species of 17 families. Six endangered species listed on the Red List of Invertebrates of the Czech Republic were recorded. These included the wolf spider Alopecosa solitaria (Herman, 1879) and the thermophilic crab spiders Ozyptila pullata (Thorell, 1875) and O. simplex (O. Pickard-Cambridge, 1862). The endangered Euryopis quinqueguttata Thorell, 1875 and Myrmarachne formicaria (De Geer, 1778) were only collected from land snail shells. The critically endangered Dysdera hungarica Kulczyński, 1897 was probably the most important discovery, known only from the warmest locations of South Moravia.
