Rod: Centromerus

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.

Total of 92 spider species were found in the peat bog Na loučkách (Krušné hory Mts., distr. Chomutov). Findings of 19 species are considered as significant: Robertus scoticus, Anguliphantes tripartitus, Aphileta misera, Centromerus pabulator, Drepanotylus uncatus, Gonatium rubens, Helophora insignis, Hilaira excisa, Kaestneria pullata, Maro lepidus, Oryphantes angulatus, Palliduphantes ericaeus, Poeciloneta variegata, Semljicola faustus, Walckenaeria alticeps, Pardosa sphagnicola, Pirata uliginosus, Iberina difficilis, Talavera parvistyla. Species Maro lepidus, Talavera parvistyla, Palliduphantes ericaeus, Semljicola faustus are highly endangered. Palliduphantes ericaeus is reported from the Czech Republic for the first time.
