Two subterranean-dwelling spiders new to Slovakia (Araneae: Linyphiidae)

Abstract

Studies of subterranean habitats in Slovakia revealed two rare linyphiid spider species new to the country, Pseudomaro aenigmaticus Denis, 1966 and Pseudocarorita thaleri (Saaristo, 1971). Pseudomaro aenigmaticus was recorded in the Malé Karpaty Mountains in western Slovakia. A male was captured in the limestone Plavecká Cave and a female was found in a granitoid mesovoid shallow substratum (MSS) in the Jajcajov jarok Valley. One pair of Pseudocarorita thaleri was found in the MSS in the Belinské skaly Nature Monument in the Cerová vrchovina Highland in southern Slovakia. This study also presents the characteristic habitus and habitats of the recorded spiders.
