4 L. Mezőfi & V. Markó Kovács & Szinetár 2015, Kovács et al. 2015b, Szinetár et al. 2015). Our results indicate that in recent years this species co- lonized almost the entire country, the central (Monorierdő), the southern (Sükösd) and the eastern (Újfehértó) parts equally. The species can also be expected to reach Serbia and Romania in the near future. Porrhomma oblitum (O. P.-Cambridge, 1871) (Fig. 5) Determination. Merrett 1994, Russell-Smith 2009 Material examined. 1 ( ,Nagykálló: 05.02.2016 – (47°53’17”N, 21°48’57”E, 116 m a.s.l., organic apple orchard). The speci- men (leg. & det. L. Mezőfi) was collected from a cardboard band. Distribution. Europe (WSC 2017): Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Great Bri- tain, Greece, Iceland, Ireland, Italy, Lithuania, Netherlands, Norway, Poland, Romania, Russia (Eastern European part), Slovakia and Switzerland (van Helsdingen 2017). Remarks. Samu & Szinetár (1999) listed seven Porrhomma species from Hungary: P. convexum (Westring, 1851), P. er­ rans (Blackwall, 1841), P. microphthalmum (O. P.-Cambridge, 1871), P. montanum Jackson, 1913, P. profundum Dahl, 1939, P. pygmaeum (Blackwall, 1834) and P. rosenhaueri (L. Koch, 1872), however the presence of P. errans and P. rosenhaueri , are uncertain (Samu & Szinetár 1999). Szinetár & Horváth (2006) cited the unpublished M.Sc. thesis of Kovács (2002) for P. oblitum , suggesting that the species also occurs in Hun- gary, but in this thesis P. oblitum was not mentioned. Conse- quently, to the best of our knowledge we report P. oblitum for the first time in Hungary, making it the eighth member of its genus in the country. This species is a facultative bark-dweller and it may occur in arable lands or various open and forest habitats, especially in semi-humid and humid ones (Blick et al. 2000, Szinetár & Horváth 2006). Identification of Porrhomma species is quite difficult. Both P. oblitum and P. montanum belong to the Porr­ homma group, where the metatarsi are spineless, femur I has only one prolateral spine and the dorsal spines are lacking, and tibia I has a prolateral spine. Porrhomma oblitum and P. montanum can be distinguished from each other only by small details of the dissected and cleared genitalia (Russell-Smith 2009, Šestáková 2011). PhilodromidaeThorell, 1870 Philodromus marmoratus Kulczyński, 1891 (syn. P. buddenbrocki Braun, 1965) (Fig. 6) Determination.

Me- zőfi) 29.07.2016 – Margit Island (47°31’19”N, 19°02’43”E, 103 m a.s.l., urban green area with floodplain-like forest vege- tation) (The male is a reared specimen, reached maturity after the ninth moult on 29.05.2017.). All specimens were collec- ted by beating from shrubs. 1 ) (det. L. Mezőfi) an additional individual, an offspring of the female collected on 29.07.2016 was also examined. This reared specimen emerged from the egg on 10.08.2016 and reached maturity after the ninth mo- ult on 19.05.2017. Distribution. Only in Austria, Bulgaria, Czech Republic, Hungary, Slovakia, Ukraine and former Yugoslavia (with ne- wer data from Serbia) (Grbić & Savić 2010, van Helsdingen 2017). Remarks. A very rare species (Bryja et al. 2005a, 2005b), which is endangered in, e.g., the Czech Republic (Řezáč et al. 2015) and occurs near wetlands or floodplain forests ( Jäger 1995, Bryja et al. 2005b).This species belongs to the Philodro­ mus aureolus group (Segers 1992) and was originally described as P. aureolus ssp. marmoratus (in Chyzer & Kulczyński 1891). Segers (1992) firstly mentioned that P. buddenbrocki is pos- sibly a synonym of P. aureolus marmoratus and later Kubcová (2004) clarified the situation and established P. buddenbrocki as a junior synonym of P. marmoratus . Although Chyzer & Kulczyński (1918), in their spider checklist reported seve- ral P. aureolus marmoratus records from the present territory of Hungary, surprisingly P. marmoratus was not included in the Hungarian checklist of spiders (Samu & Szinetár 1999), probably because of its uncertain taxonomic status. Our data provide further evidence for the occurence of P. marmoratus in Hungary. Furthermore, one individual ( ) ) was successfully reared from the egg. After the spider had emerged, it moul- ted nine times until maturity was reached. The other reared specimen ( ) ) which had been collected as a small nymph also moulted nine times until it reached adult stage. These obser- vations indicate that P. marmoratus may have nine or more instars before maturity. Pulchellodromus ruficapillus (Simon, 1885) (syn. Philodromus ruficapillus ) (Fig. 7) Determination. Muster et al. 2007, Kastrygina & Kovblyuk 2014 Material examined. 2 (( , Nagykálló: 09.05.2016 – (47°53’17”N, 21°48’57”E, 116 m a.s.l., organic apple orchard) (reared specimens, final moulting reached on 25.07.2016). The specimens (leg. & det. L. Mezőfi) were collected by bea- ting method from canopy of apple trees. Distribution. Mediterranean to Kazakhstan (WSC 2017). In Europe it was found in Albania, Austria, France, Greece (including North Aegean Islands and Crete), Hungary, Ita- ly, Portugal, Romania, Spain and Ukraine (van Helsdingen 2017). Remarks. In 2012 the genus Pulchellodromus was separated from the genus Philodromus by Wunderlich (2012), and the genus now contains 13 cryptic species (WSC 2017), mostly from the Mediterranean region (Muster et al. 2007,Wunder- lich 2012).Two of them have data from Hungary: P. pulchellus (Lucas, 1846) (Déri et al. 2007, Kancsal et al. 2010) and P. ruficapillus , the latter of which seems to have the largest dis- tribution area among the other species of the genus (Duma Fig. 5: Cleared, dis- sected epigyne/vulva of Porrhomma oblitum female from Hungary; dorsal view
