Investigation of spiders (Araneae) of the Nature Monument Jesličky (South Moravia, Czech Republic)

Faunistic records of spiders (Araneae) in the Nature Monument Jeslicky (South Moravia, Czech Republic) are presented. Spiders were collected by pitfall trapping in 2009 and by sweeping of the herb vegetation in 2011. During the both periods a total of 847 specimens were collected, from which 617 adult spiders were determined. We found 88 species belonging to 20 families. Seven species listed on the Red List of Invertebrates of the Czech Republic were recorded: Titanoeca schineri L. Koch, 1872, Scotina celans (Blackwall, 1841), Haplodrassus dalmatensis (L. Koch, 1866), Ozyptila pullata (Thorell, 1875), Ozyptila simplex (O.P-Cambridge, 1862) and Marpissa nivoyi (Lucas, 1846). To the most significant finding belongs a very rare and endangered (EN) Micaria guttulata (C. L. Koch, 1839). A significant and rich finding of bioindicators of the well preserved steppe habitats Atypus piceus (Sulzer, 1776), Eresus kollari Rossi, 1846 and Alopecosa sulzeri (Pavesi, 1873) are to be mentioned.
