Data on the spider fauna from the forest ecosystems of the Děvín National Nature Reserve (South Moravia, Czech Republic) are presented. The research was carried out on 15 randomly chosen research plots in oak-hornbeam forest stands within different management regimes. Spider sampling was done by pitfall trapping from May to October 2016. Overall, 3683 adult spiders belonging to 22 families, 70 genera and 116 species were collected. The families Linyphiidae, Lycosidae, Gnaphosidae and Thomisidae exhibited high species richness. The most abundant species were Pardosa lugubris (Walckenaer, 1802) and Trochosa terricola Thorell, 1856. Faunistically remarkable species were Atypus piceus (Sulzer, 1776), Drassyllus villicus (Thorell, 1875), Gnaphosa montana (L. Koch, 1866), Panamomops affinis Miller & Kratochvíl, 1939 and Walckenaeria monoceros (Wider, 1834). The record of Gnaphosa montana is one of the first accounts of this psychrophilic spider from European lowlands. Of the identified species, 23 are listed in the Red List of Threatened Species in the Czech Republic (EN – 1 species, VU – 12 species, LC – 10 species).

Members of the genus Gnaphosa belong to the largest gnaphosid spiders. They are particularly interesting in nature conservation as their distribution is mainly restricted to disappearing natural non-forest habitats. In Europe, several Gnaphosa species groups occur. The exclusively Palaearctic group G. bicolor is characterised by a retrolaterally-shifted embolus, which occupies at least part of the middle one-third of the palpal bulb; females have laterally expanded epigyne and often have very elongated median epigynal ducts (Ovtsharenko et al. 1992). So far four species of this group have been identified in Europe, with a fifth species found in Central Asia (G. tarabaevi Ovtsharenko, Platnick & Song, 1992). Two of the European species, G. bicolor (Hahn, 1831) and G. badia (L. Koch, 1866), are well known and their taxonomy and nomenclature is stable, but the same does not hold true for the other two.

The taxonomy and nomenclature of the rare European gnaphosid spiders Gnaphosa alpica and Gnaphosa modestior have been confused. Simon (1878) first described females of G. alpica from southwestern Alps. Almost twenty years later, Władysław Kulczyński described two more species, Gnaphosa modestior (single male from northeastern Croatia, and females from central Hungary and southwestern Romania) and G. laeta (single female from northeastern Hungary) (Chyzer & Kulczyński 1897), however the author expressed doubts about the species status of G. laeta and suggested that it may be an abberant female Gnaphosa modestior. Ovtsharenko et al. (1992) later published a review of the north Asian Gnaphosa, including the species from Europe, in which they come to incorrect conclusions regarding the identities of the three aforementioned species/names due to a lack of available material. Recently, we were given the opportunity to review this group of species through the study of new material. We redescribe Gnaphosa modestior and G. alpica (including designation of the lectotype and first description of a male) and describe a new, closely related species G. dolanskyi sp. n. from the southeastern Europe and adjacent regions of Asia. Further, we remove G. laeta from synonymy of G. alpica and suggest it to be a synonym of Gnaphosa modestior.

Results of the exploration of the araneofauna and the entomofauna in West Bohemian heathlands are presented. Spiders and carabid beetles were collected during the vegetation seasons in 2011 and 2012 by the method of pitfall trapping. In total, 3188 specimens of 171 Araneae species and 2168 specimens of 93 Carabid species were determined. The most frequent spiders were Xerolycosa nemoralis (Westring, 1861), a common forest species. The following identified species are listed among the endangered spiders in the Czech Republic in the category „endangered“: Alopecosa schmidti (Hahn, 1835), Micaria dives (Lucas, 1846),  Peponocranium orbiculatum (O. P.-Cambridge, 1882), in the category „vulnerable“: Centromerus incilium (L. Koch, 1881), Evansia merens O. P.-Cambridge, 1900, Metopobactrus prominulus (O. P.-Cambridge, 1872), Arctosa figurata (Simon, 1876), Arctosa lutetiana (Simon, 1876), Pardosa nigriceps (Thorell, 1872), Gnaphosa bicolor (Hahn, 1833), Xysticus striatipes L. Koch, 1870, Evarcha laetabunda (C. L. Koch, 1846) and Trichopterna cito (Blackwall, 1841). The most remarkable species of the Carabids were the Amara equestris equestris (Duftschmid, 1812), Amara pulpani Kult, 1949, Bradycellus ruficollis (Stephens, 1828), Carabus arcensis arcensis Herbst, 1784, Carabus problematicus harcyniae Sturm, 1815, Cymindis axillaris axillaris (Fabricius, 1794), Cymindis vaporariorum (Linné, 1758), Masoreus wetterhallii wetterhallii (Gyllenhal, 1813), Olisthopus rotundatus rotundatus (Paykull, 1790). Studied material was reposited at the Department of Zoology of the West Bohemian Museum in Pilsen.
