26 A. Šestáková, A. Mock, J. Christophoryová & P. Gajdoš of soil and rock fragments of about 2 cm in diameter. Here, we used the same type of subterranean sampling devices as in locality A (Mock et al. 2015). The traps were exposed from May 2012 to October 2013. Microphotographs of specimens were taken using Ca- non EOS 100D and 1000D digital cameras mounted on a stereomicroscope (Intraco Micro STM 823 5410 and Zeiss Stemi 2000-C) and processed using the EOS Utility soft- ware. Digital images were combined with Zerene Stacker v. 1.04 and measurements were taken using AxioVision v. 4.6. The voucher specimens are deposited in 70% ethanol in the collection of the first author. Spiders were identified by V. Růžička, and the male of Pseudomaro aenigmaticus was con- firmed by T. Blick. Nomenclature follows the World Spider Catalog (2017). Results and discussion Araneae (Linyphiidae) Pseudocarorita thaleri (Saaristo, 1971) Material examined. SLOVAKIA: Cerová vrchovina High- lands, 1 ) , 1 ( – Belinské skaly, subterranean sampling devices, jar at 15 cm below the surface, 12.X.2012–2.V.2013 (leg. T. Šašková and A. Mock). Female (Fig. 5): Body length 1.07 mm. Prosoma 0.52 mm long and 0.44 mm wide. Male (Fig. 6): Opisthosoma missing. Prosoma 0.61 mm long and 0.46 mm wide. This tiny linyphiid species was described as Maro thaleri by Saaristo (1971) based on a single female collected in the Aus- trian Alps.Thaler (1980) added a description of the male, re- vising an older collection of spiders from the Austrian and Swiss Alps. The species was placed in the genus Maro with some hesitation. After the male was found, Wunderlich (1980) created a monotypic genus Pseudocarorita for this spe- cies based on its similarity to the genus Carorita . Habitat. Pseudocarorita thaleri occurs mainly in litter (Nent- wig et al. 2017), but is also regularly found in trunk eclec- tors in the low mountain ranges of Germany (Blick 2011) and occasionally in caves; it is considered a trogloxene (Blick pers. comm.). The type specimen was captured in Austria by sieving pine needles in an Alpine montane forest at 900 to 1000 m a.s.l. (Saaristo 1971). Additional Alpine records were documented from different localities at 435 to 2190 m a.s.l. (Thaler 1980). In the Czech Republic the species occurs in ragged terrain at lower altitudes in the litter of various fo- rests, such as oak, alder and spruce (Buchar & Růžička 2002). Fig. 3: Locality B.
