Pannonic salt marshes revealed six new spiders to Slovakia (Araneae: Gnaphosidae, Linyphiidae, Lycosidae, Theridiidae)

Pannonic salt marshes – important habitats for ground-active spider communities

“…Our results indicated that salt marshes are not only important for their high species richness, but also because they are inhabited by many rarely recorded and endangered species. We revealed the occurrence of 28 threatened and 18 potentially threatened species listed in the Red list of Slovakia (Gajdoš & Svatoň 2001). Another 11 faunistically important species were documented from Slovakia only recently, six of them from salt marshes (Gajdoš et al 2019).…”

“…Faunistically important is also the finding of Micaria rossica Thorell, 1875, which was reported from only one locality in the Malá Fatra (Svatoň 1983(Svatoň , 1984. The recently published species Gnaphosa rufula (L. Koch, 1866) from Slovakia (Gajdoš et al 2019) was found so far only in the Bokroš saltmarsh.…”

Another 11 faunistically important species were documented from Slovakia only recently, six of them from salt marshes (Gajdoš et al 2019). We also collected three new species for the Slovak fauna ( Dactylopisthes digiticeps , Ozyptila sanctuaria and Pardosa tenuipes ).…”

“…Interestingly, Z. mundus has also recently been reported from salt marshes on the Atlantic coast of southwestern France (Ridel et al 2021). Two other species, Metopobactrus deserticola Loksa, 1981 (endemic of the Pannonian region) and Gnaphosa rufula , can be included in this group because they show a strong association to xerothermic saline habitats (Gajdoš et al 2019). The species Zodarion italicum (Canestrini, 1868), only recently published for the first time from Slovakia (Gajdoš et al 2023), shows spreading tendencies in Europe, therefore we expect its expansion in Slovakia as well.…”

“…In the period 2016–2019, we collected about 10,000 individuals of spiders. Initial results revealed six species new for our fauna (Gajdoš et al 2019). The most interesting records of rare spider species are summarized here, including the discovery of three new species for the Slovak fauna: Ozyptila sanctuaria (O. Pickard-Cambridge, 1871) Dactylopisthes digiticeps (Simon, 1881) and Pardosa tenuipes L. Koch, 1882.…”
