Air blown sands areas and its habitats are very rare in Europe as well as many spider species, which occure there. Research was focused on spiders of sandy grassland and its ecotones near the town of Hodonín. Three lines of pitfall traps were used (one in grassland and two in its ecotones). Research took place in growing seasons of the years 2008, 2009, 2010 and 2011. Total number of collected adult spider specimens was 11743, they belong to 160 species and 21 families. It was found out, that 15 following species are included in the Red List of threatened species in the Czech Republic: Critically Endangered – Haplodrassus bohemicus Miller & Buchar, 1977, Sitticus zimmermanni (Simon, 1877), Titanoeca psammophila Wunderlich, 1993, Uloborus walckenaerius Latreille, 1806; Endangered – Euryopis laeta (Westring, 1861), Haplodrassus minor (O. P.-Cambridge, 1879), Micaria dives (Lucas, 1846); Vulnerable – Agroeca lusatica (L. Koch, 1875), Arctosa perita (Latreille, 1799), Haplodrassus dalmatensis (L. Koch, 1866), Myrmarachne formicaria (De Geer, 1778), Pellenes nigrociliatus (Simon, 1875), Scotina celans (Blackwall, 1841), Taranucnus setosus (O. P.-Cambridge, 1863), Titanoeca schineri L. Koch, 1872. Another 19 remarkable species were also found. The finding of one new species for the fauna of the Czech Republic [Sintula spiniger (Balogh, 1935)] and two new for the territory of Moravia [Mermessus trilobatus (Emerton, 1882) and Zelotes exiguus (Müller & Schenkel, 1895)] are the most important.
