During an arachnological survey in the Šumava National Park in 2016, two very rare spider species were discovered: Araneus saevus (Araneidae) was recorded for the second time, 45 years after its first report in the Czech Republic. The species is therefore no longer regionally extinct, and can be considered critically endangered. Theridion boesenbergi (Theridiidae) was recorded for the first time in the Šumava Mts. Ecological characterisation of the species is improved, being more psychrophilous than was previously expected. Almost all collected specimens of both species from the Czech Republic are deposited in the National Museum in Prague.
