03D2BC57FF8DFF8BFC2B0EE72C37FA54.taxon	discussion	1) Acartauchenius scurrilis (O. P. - Cambridge, 1873) – occurs sporadically and scarcely in xerothermic grasslands and also live near ants (Nentwig et al., 2020). It was documented also warm dry oak forests, sand habitats, stone habitats, etc. and from anthropogenic habitats (e. g. vineyards). Host ants: Lasius niger L., L. avus Fabricius, Formica rufa L. and Tetramorium caespitum L. (Cushing, 1997; Buchar, Růžička, 2002). Obenberger (1949) and Miller (1971) mentioned only T. caespitum. Apparently, it highly prefers the last ant species (Franc, 2007). Recent record: Domaníky (48 ° 15 ʹ 35.30 ” N, 18 ° 58 ʹ 44.08 ” E, 208 m a. s. l.), andesite rocky grassland, in the colony of T. caespitum, May 4, 2020, 3 ♂ and 2 ♀. A relatively large number of records from Slovakia are available (Gajdoš et al., 1999; Franc, 2007). The further recent record: Jurský Šúr surroundings (7769), April 2009 – 2011, 2 specimens (Dankaninová, Gajdoš, 2012); Malé Kršteňany (7376), April 2015 (Franc, Fašanga, 2017); Dolné Vestenice (7276), April – May 2010 (Melicherčíková, 2010). 2) hvyreosthenius biovatus (O. P. - Cambridge, 1875) – occurs sporadically and rarely together with ants (Nentwig et al., 2020) especially in forests and grasslands of warmer areas, though it may be locally abundant. Host ants: Formica polyctena Foerster, F. pratensis Retzius, F. fusca L. and F. sanguinea Latreille (Cushing, 1997; Buchar, Růžička, 2002), also F. lugubris Zetterstedt (Robinson, 1998). Miller (1971) mentioned the same ant species except as F. polyctena, while Obenberger (1949) noted only F. pratensis and F. rufa. It has also occasionally been recorded away from ant nests (Roberts, 1987). Recent records: Hajnáčka (48 ° 12 ʹ 46.74 ” N, 19 ° 56 ʹ 17.93 ” E, 290 m a. s. l.) in the colony of Formica rufa in the older deciduous forest (beech, oak and hornbeam) February 17, 2019, more than 10 ♀ V. Franc and V. Hemala lgt.; Banská Štiavnica – the ‘ Little Water Damʹ (48 ° 28 ʹ 05.48 ʺ N, 18 ° 53 ʹ 03.94 ʺ E, 778 m a. s. l.), in the colony of F. rufa in a mixed forest February 14, 2020, 8 ♀, V. Franc and V. Hemala lgt. et coll. Only a few records from Slovakia are available, for example: the town of Banská Bystrica (7280) (Franc, 2007) and surroundings (Franc, 2005); the Hronská pahorkatina hills (804), Dudich et al. 1940 (in Gajdoš et al., 1999); Malanta near the town of Nitra (7674 d) (Gajdoš, 1993) and in the town Žilina (6778) (Kratochvíl, Miller, 1937). It is a little-known species, due to its hidden way of life, but it actually seems to be rather abundant.	en	Franc, Valerián, Hemala, Vladimír (2020): New remarkable records of myrmecophilous spiders (Araneae) in Slovakia.

03D2BC57FF8EFF89FC3C0D2E2C2BFEE2.taxon	discussion	3) Mastigusa arietina (Th orell, 1871) – this scattered species occurs rarely in warm habitats, especially open forests (Fig. 1) and on xerothermic slopes. Th ey live under bark or in formicaries (Nentwig et al., 2020). Host ants: in the nests of the ants Lasius brunneus and L. fuliginosus (Brian, 1977). Th ey are not speci ed in the literature, it obviously may live together with a large range of ant species. New recent records: Jalovec (49 ° 09 ʹ 28.00 ʺ N, 19 ° 37 ʹ 54.70 ʺ E, 768 m a. s. l.), in the colony of Formica rufa near the chapel (Fig. 1), March 10, 2019, 1 ♀ and 2 juveniles V. Franc and V. Hemala lgt. Th is mountain record at the foot of the Západné Tatry Mts is highly notable!; Banská Štiavnica – the ‘ Little Water Dam’ (48 ° 28 ʹ 05.48 ʺ N, 18 ° 53 ʹ 03.94 ʺ E, 778 m a. s. l.), in the colony of F. rufa in mixed forest February 14, 2020, 1 ♀ and 1 juvenile, V. Franc and V. Hemala lgt. et coll. Th e following records from Slovakia are available, for example: the Rohy National Nature Reserve near the town of Detva (7482 a / c), in a under-stone colony of Lasius niger, March 3, 1991, 1 ♂; the village of Plášťovce (7879 b), in the colony of Messor muticus Nylander, on a xerothermic slope, April 1, 1994, 2 ♀ [together with the very rare leiodid-beetle Attaephilus arenarius Hampe!]; the Rykynčice village (7779 d), in the same circumstances, April 9, 1994, 2 ♂, 1 ♀, all records V.
