Icius subinermis in Hungary 39 specimen’s opisthosoma has a light brown or off-white tinc- ture and reddish-brown spots which form a horseshoe-shaped pattern.The epigyne and vulva are shown in Fig. 2. Discussion Icius subinermis is known from Spain, France (including Cor- sica), Italy (including Sicily and Sardinia), Portugal, Mace- donia, Slovenia, Switzerland (Helsdingen 2017), Germany (Blick et al. 2016) and Serbia (Stanković 2012). I. subinermis was also reported from the Netherlands (Helsdingen 2006) and recently from the Czech Republic (Šich 2015) although its establishment has not been confirmed in these two coun- tries. This species generally occurs in moist habitats, for examp- le near streams or on moist meadows. It builds a silken retreat on rush plants or under rocks near rivers or creeks (Stanković 2012). It may also occur on trees, especially in the vegetation bordering aquatic environments, but is usually present at the waterside at the time of its reproduction. Females are often seen guarding their eggs (Ledoux 2007). Although I. subinermis has a Mediterranean origin (Ali- cata & Cantarella 1994), it has also been reported from Central and Western Europe (e.g. from Germany and the Netherlands) ( Jäger 1995, Helsdingen 2006). Icius subiner- mis probably lives in moist habitats under natural conditions (Stanković 2012, Leroy et al. 2014). However, it was also ob- served in urban environments or near residential areas ( Jäger 1995, Komnenov 2005, Kostanjšek & Fišer 2005, Helsdingen 2006, Stanković 2012). Furthermore, in most cases the speci- mens were found in buildings (e.g. in a house, greenhouse or apartment) ( Jäger 1995, 1996, Komnenov 2005, Helsdingen 2006).This supports the findings of Nedvěd et al. (2011) that occurrence in buildings is a prerequisite for range expansi- on in many arachnid species. Moreover, these observations suggest that an urban environment and its microclimate may provide suitable conditions for this species, particularly nor- thwards from the Mediterranean region. How this specimen of I. subinermis got to Hungary is un- clear and hard to speculate about.The warming climate and/ or human mediation could be suspected. Since the specimen was found in a semi-natural habitat in Budapest, it may have an established population here. To confirm this, further sur- veys are needed, mainly in residential areas and semi-natural habitats nearby. In Hungary, the most comprehensive checklist of the Sal- ticidae family was published by Szűts et al. (2003), with 70 salticid species from Hungary. Since then several jumping spider species have been reported: Chalcoscirtus nigritus (Tho- rell, 1875), Saitis tauricus Kulczyński, 1904 (Szita et al. 2004), Sitticus inexpectus Logunov & Kronestedt, 1997 (Déri et al. 2007), Euophrys herbigrada (Simon, 1871), Talavera parvistyla Logunov & Kronestedt, 2003 (Kis 2007, cited in Kovács et al. 2012) and Talavera aperta (Miller, 1971) (Batáry et al. 2008). The Fauna Europaea Database lists 78 valid salticid species for Hungary (Helsdingen 2017). However E. herbigrada and Talavera monticola (Kulczyński, 1884) (for the latter see Szűts et al. 2003) is missing from the list, whereas Pellenes campy- lophorus (Thorell, 1875), Aelurillus simplex (Herman, 1879), Myrmarachne simonis (Herman, 1879) and Synageles dalmati- cus (Keyserling, 1863) are erroneously listed. Pellenes campylo- phorus was recognized as a nomen dubium by Logunov et al. (1999), while A. simplex, M. simonis and S. dalmaticus have no records from the present territory of Hungary. Although the latter three species were on the spider faunal list of Hungary made by Chyzer & Kulczyński (1918), these records origina- ted from regions that are not part of Hungary today. Chyzer & Kulczyński (1918) reported A. simplex from Doroszló (Do- roslovo, now in Serbia), M. simonis (as Salticus simonis ) from Körösfeketetó (Negreni, now in Romania) and S. dalmaticus from Buccari (Bakar, now in Croatia, also erroneously noted as being in Hungary by Logunov 2004) and Crkvenica (Crik- venica, now in Croatia). In total, including the new record of I. subinermis , 77 jum- ping spider species are recorded from Hungary so far.
