Distribution. Morocco, Algeria, Europe, Caucasus (World Spider Catalog 2020).This species has been reported in many European countries, but seems to be lacking in the northern part of Europe, including the Baltic region and Scandinavia (Nentwig et al. 2020, van Helsdingen 2013, 2020). It was first found and described in Germany (Wunderlich 1994), and thereafter recorded in Europe in Hungary (Mikhailov & Szinetár 1997), Belgium and the Netherlands (Roberts 1998), Ukraine, Bulgaria and Moldavia (Mikhailov 2003, Polchaninova & Prokopenko 2019), Switzerland (Pozzi & Hänggi 1998), Great Britain and France (Merrett 2001), Czechia (Buchar & Růžička 2002), Slovenia (Kuntner 1997), Serbia (Grbić & Savić 2010), the European part of Russia (Ponomarev & Polchaninova 2006, Sozontov & Esyunin 2012, Ponomarev & Khnykin 2013), the European part of Turkey (van Helsdingen 2013), North Macedonia (Komnenov 2014), Spain and Greece (Bosmans et al. 2017), Croatia and Bulgaria (Blagoev et al. 2018), Italy (Pantini & Isaia 2019), Cyprus (Bosmans et al 2019) and now in Slovakia. Bosmans et al. (2017) inadvertently confused the country names Slovenia and Slovakia, thus giving the impression that the occurrence of this species in Slovakia had already been published by Kuntner & Šereg (2002).

The species has so far been confirmed in Slovakia at three of the localities described above, but we consider it likely that C. pseudoneglecta might have been mistaken in the past with the very similar species – C. neglecta. A review of old records of C. neglecta in Slovakia is therefore called for. This has already been done elsewhere: the first reports of C. pseudoneglecta from Great Britain included reassignment of older reports of C. neglecta (Merrett 2001).

Body size. Female: body length 5.94–7.41 mm; prosoma length 2.38–2.47 mm, width 1.85–1.94 mm; opisthosoma length 3.72–5.14 mm, width 2.29–2.98 mm.

General appearance of the female from dorsal and ventral side is as depicted in Figs 3–4 and its epigyne as in Figs 5–6.

Male: body length 5.01 mm; carapace length 2.40 mm, width 1.78 mm; opisthosoma length 2.36 mm, width 1.60 mm. General appearance of the male from dorsal side as depicted in Fig. 7; its bulbus is shown in Fig. 8 and details of the tibial apophysis in Fig. 9.

Habitats. This species is classified as xerophilic and thermophilic (Buchar & Růžička 2002, Isaia et al. 2007), but very little is known about its biology. It has been recorded in dry meadows and on warm, south-exposed slopes (Nentwig et al. 2020). In Germany, it was reported from a vineyard fallow adjacent to semi-dry grasslands (Wunderlich 1994). In Britain, it has been recorded on sand dunes with sparse vegetation on fore-dunes and also on dense grassland on stabilised dunes (Merrett 2001). It has also been recorded on sand dunes in Belgium and the Netherlands (Russell-Smith 2009). However, further south in Europe, it was collected in oak forests in France (Le Peru 2007), in deciduous woodland forest edges in Serbia (Grbić & Savić 2010), and from relatively dry to mesophilic grassland habitats in Germany and Hungary (Russell-Smith 2009) and Serbia (Grbić & Savić 2010). Russell-Smith (2009) collected this species in a sycamore woodland on the Mediterranean coast of Turkey. In the European part of Turkey, it was found in a wet area with Juncus sp. (van Helsdingen 2013). Italian specimens were recorded on low vegetation in meadows (Isaia et al. 2007). Other specimens were collected in ungrazed dry grassland (Milasowszky et al. 2016) and from salt meadows in Austria (Milasowszky & Waitzbauer 2008). The only historical record without information on the habitat is from the Czech Republic. A specimen recorded in 1958 in Lednice (south Moravia – the warmest part of Czechia) was discovered in F. Miller's collection among the material of C. neglecta (Buchar & Růžička 2002). All our records are from southern part of Slovakia (Pannonian Region) from areas with very dry and hot climate. Based on published records and our findings, it has been confirmed that C. pseudoneglecta occurs in both natural and anthropogenic habitats, but appears to prefer dry and warm habitats.

Red list. Clubiona pseudoneglecta was included in the red lists of many countries or regions. In Belgium it is listed in the regional red list of Flanders in category IN (Indeterminate) (Maelfait et al. 1998), in Czechia in the national red list in category CR (Critically Endangered) (Řezáč et al. 2015) and in the regional red list of the Czech Carpathians in category CR (Critically Endangered) (Gajdoš et al. 2014), in Germany in the category G (Generally Threatened) (Blick et al. 2016) and in the regional red list of Bavaria in category 2 (Endangered) (Blick & Scheidler 2004), in the United Kingdom in the national red list in category VU (Vulnerable) (Harvey et al. 2017), in Hungary in the regional red list of the Hungarian Carpathians in category LC (Least Concern) (Gajdoš et al. 2014), and in Slovenia in the national red list in category R (rare) (Uradni list Republike Slovenije 2002).

Material. SLOVAKIA, Galanta, urban parks; the specimens were in the bark trap, suggesting that the species lives under the bark of Tilia cordata and Pinus nigra, 3. Dec. 2017 – 18. Jan. 2018, 2 ♀♀, leg. K. Román & C. Szinetár, det. C. Szinetár.

Distribution. This species has been recorded in Europe in ten countries, namely Austria and Germany (Bauer & Grabolle 2012, Bauer & Höfer 2017, Bauer et al. 2019), Bulgaria (Blagoev et al. 2018), France (Bosselaers et al. 2009), Spain – Mallorca (Pons & Palmer 1996), Croatia (Grbac et al. 2019), Hungary (Kolosváry 1932), Italy (Trotta 2005, Pantini & Isaia 2019), Slovenia (Kostanjšek & Kuntner 2015), Ukraine (Kovblyuk & Nadolny 2009), and now in Slovakia. There are also records from Turkey and Israel (World Spider Catalog 2020).

Body size. Female: body length 4.20 and 4.82 mm; prosoma length 1.60 and 1.85 mm, width 1.70 and 1.81 mm; opisthosoma length 2.60 and 2.97 mm, width 2.20 mm each.

General appearance of the female from dorsal and ventral side is as depicted in Figs 10-11, and its epigyne as in Fig. 12.

Habitat: Paratrachelas maculatus was collected using pitfall traps and under tree bark in the sub-mediterranean parklands of south Crimea (Kovblyuk & Nadolny 2009). Several records point to its synanthropic occurrence in Europe. In Austria, the species was found inside a house, and in Germany in a cellar and bathroom (Bauer & Grabolle 2012, Bauer et al. 2019). Recently, it has been observed on the walls of the buildings in the town centre of Keszthely (Balaton Uplands, Hungary) (B. Keresztes pers. comm.). So far, the species has not been considered a typically bark-dwelling Central European spider (Szinetár & Horváth 2006). Specimens from Slovakia have been found outside buildings under the bark of two different tree species (Tilia cordata, Pinus nigra). The observations of Kovblyuk & Nadolny (2009) and our data from Slovakia support classifying P. maculatus as a facultative bark-dweller, which permanently or seasonally uses tree trunks as typical, but not exclusive, microhabitats. This is similar to other facultative bark-dwellers such as Gnaphosa montana (L. Koch, 1866) or Phrurolithus festivus (C. L. Koch, 1835), for which rocks, cracks in rocks, and artificial walls also constitute typical habitats (Szinetár & Horváth 2006). We assume that this species is already present on the trees of city parks of many other countries in Central Europe. The further spread of P. maculatus to the north and west is to be expected.

Red list: Paratrachelas maculatus has not been included in any Red List, e.g., in the German Red List this species is still stated as not established (Blick et al. 2016). Based on new records Bauer et al. (2019) discussed whether it can be regarded as established, alien species in Germany.
