The first data about harvestmen in Slovakia
can be found in 1873, when Sørennsen (1873) mentioned
occurence of Nemastoma bidentatum in the vicinity of Bardejov
The first systematic investigation of Slovak opiliofauna was performed by
Czech arachnologists. Kratochvíl (1934) presented the first critical account of harvestmen from
the former Czechoslovakia. He was the first who paid serious attention to the Slovak fauna.
In 1956, Vladimír Šilhavý published a thorough manual of the harvestmen
"Fauna of Czechoslovakia – Harvestmen", with a general introductory part (Šilhavý 1956).
This manual contains detailed description of 64 species (opilionids
occuring and also species expected in the Czech Republic and Slovakia).
Since 1993, the new generation of Slovak researches begun to publish (Ivan Mihál, Boris Astaloš, Peter Mašán, Slavomír Stašiov, Peter Maršalek).
summarized informations about occurence and ecological requirements of
harvestmen in Slovakia in his monography "Opiliones of Slovakia".
Bibliography about Slovak Opiliones counts 230 papers (including 25 unpublished theses).
