Arachnologische Mitteilungen 54

Arachnologische Mitteilungen / Arachnology Letters 54: 38-40 Karlsruhe, September 2017 The spider fauna of Hungary is well studied (Samu & Szi- netár 1999). Due to intensive research and more specialized collecting methods, new records frequently emerge. Some of these new species are indigenous, others are newcomers. In- ternational trade is one of the most important factors that contribute to the spread of invasive arthropod species, inclu- ding spiders (Nedvěd et al. 2011). In addition, climate change may also facilitate the establishment of exotic species origina- ting from warmer areas (Nentwig 2015). Due to a warmer cli- mate,Mediterranean spider species have extended their range northwards (e.g. Kumschick et al. 2011, Nedvěd et al. 2011). Among 87 introduced alien spiders, 44 expanded their range from the Mediterranean or the Eastern Palaearctic to western and northern Europe (Kobelt & Nentwig 2008). Jumping spiders (Salticidae) are one of the most common spider families (after Theridiidae and Pholcidae) in which species are indicated as alien (Nentwig 2015). Salticidae is the richest family worldwide with over 620 genera and more than 5900 described species (WSC 2017). Within Salticidae, the genus Icius comprises 34 described species (WSC 2017) and five Icius species are confined to the Mediterranean region of Europe (Nentwig et al. 2017). Two of them, I. hamatus (C.L. Koch, 1846) (Tomasiewicz & Wesołowska 2006, Schäfer & Deepen-Wieczorek 2014) and I. subinermis Simon, 1937 ( Jäger 1995, Helsdingen 2006) have also been reported from Central and Western Europe in recent years. No representa- tives of Icius have been found in Hungary until now (Szűts et al. 2003, Helsdingen 2017). Material and methods The arthropod community of Acer campestre was surveyed in a green area of Budapest (Mátyás tér, 47°29'32"N, 19°4'48"E, 110 m a.s.l.), Hungary, in the growing season of 2016. This area is covered by trees (e.g. Acer spp., Fraxinus spp., Robi- nia spp.), small bushes (e.g. Berberis spp., Juniperus spp., Rosa spp.), grassy patches and concrete surfaces, and surrounded by multi-storey buildings and traffic roads. The specimen was collected on June 22 nd 2016 using the bea­ ting method. The study was carried out at the Department of Entomology of Szent István University.The specimen was examined with Leica MZ6 and photographed with a Sony XCD-SX90CR camera attached to a Zeiss Stemi stereomi- croscope. We used the key available in Alicata & Cantarella (1994) for identification. The female vulva was prepared and macerated with 20 % KOH and photographed with a Zeiss Imager A2 light microscope equipped with AxioCam MRc5. Measurement are given in millimetres.The specimen was de- posited in the second author’s private collection. Results The adult female jumping spider specimen was identified as Icius subinermis Simon, 1937 (leg. D. Korányi, det. L.Mezőfi). The specimen’s general appearance is shown in Fig 1. The First record of the jumping spider Icius subinermis (Araneae, Salticidae) in Hungary Dávid Korányi, László Mezőfi & Viktor Markó doi: 10.5431/aramit5408 Abstract. We report the first record of Icius subinermis Simon, 1937, one female, from Budapest, Hungary. We provide photographs of the habitus and of the copulatory organ. The possible reasons for the new record and the current jumping spider fauna (Salticidae) of Hungary are discussed. So far 77 salticid species (including I. subinermis ) are known from Hungary.

Wir berichten über den ersten Nachweis von Icius subinermis Simon, 1937, eines Weibchens, aus Budapest, Ungarn. Fotos des weiblichen Habitus und des Ko- pulationsorgans werden präsentiert. Mögliche Ursachen für diesen Neunachweis und die Zusammensetzung der Springspinnenfauna Ungarns werden diskutiert. Bisher sind 77 Springspinnenarten (einschließlich I. subinermis ) aus Ungarn bekannt.
