8 Nieuwsbrief SPINED 38 UPDATE ON THE SPIDERS (ARACHNIDA, ARANEAE) OF CALABRIA, ITALY Steven IJland Gabriel Metzustraat 1, 2316 AJ Leiden ([email protected]) & Peter J. van Helsdingen European Invertebrate Survey – Nederland, P.O. Box 9517, 2300 RA Leiden, Netherlands ([email protected]) ABSTRACT During the spring of 2017, spiders of 203 identified species were collected in the region of Calabria, Southern Italy. A list of collected species is given. Fifty five species are new records for Calabria. Five species are reported as new for Italy: Pardosa paludicola (Clerck, 1757), Evarcha michailovi Logunov, 1992, Heliophanus simplex Simon, 1868, Dipoena umbratilis (Simon, 1873), and Xysticus macedonicus Šilhavý, 1944. Some species could not be identified as yet: Spermophorides spec., Diplocephalus spec., Lepthyphantes s.l. spec., Pelecopsis spec., and Xysticus spec. The status of Platnickina nigropunctata (Lucas, 1946) is discussed. Key words: Araneae, faunistics, Calabria, Italy, southern Italy INTRODUCTION This paper is the fourth in a series on the spider fauna of southern Italy. The first dealt with a field trip to Gargano in 2011, the second with the surroundings of Castellabate, province Salerno in the region Campania in 2013, the third with the borderland of the regions Basilicata and Calabria in 2015 (see IJland et al. 2012, 2014, 2016) and finally the present paper dealing with a field trip to the provinces of Cosenza and Catanzaro in Calabria in 2017. Fieldwork was carried out during the period 7-19 May 2017 (PvH) and 7-13 May 2017 (SIJ). In total 1059 spiders were collected (437 males, 606 females and 16 juveniles (of recognizable species)). Altogether 202 species could be identified, five of which are new for Italy and 55 new for Calabria. Six species could not be identified as yet. The localities where we collected are listed below and shown on a map (fig. 1). The material of the present report is divided between the private collection of Steven IJland and the collection of Naturalis Biodiversity Centre at Leiden, the Netherlands. Coordinates are given as WGS84. The Fauna Europaea database (Van Helsdingen, 2018) was used as source of information on species distributions in Europe. The online checklist of Pantini and Isaia was used for species distribution information within Italy (Pantini & Isaia, 2018). For occurrence of species in Calabria the recent publication by Pantini and Mazzoleni (Pantini & Mazzoleni, 2018) was used. THE SPIDER FAUNA OF ITALY In previous publications we stated that the spider fauna of southern Italy appeared to be very rich but seriously understudied. In 2018, Pantini and Mazzoleni (Pantini & Mazzoleni 2018) summarized the current knowledge on the arachnofauna of Calabria, based on publications and unpublished records. They reported 456 species, 213 genera and 41 families for the region. The number of species seems to be very low for a diverse region like Calabria. As a result of just two weeks of collecting in 2017, we could add 55 species new to the fauna of Calabria, five of which are new to the fauna of Italy. Besides, some specimens were found which likely belong to species new to science, although in this paper we refrain from formal descriptions for reasons indicated. The region is best characterized as agricultural landscape (olive orchards, pastures) with forested areas. Calabria has a considerable variety of habitats and reaches from the coast up to the highest top of the Calabrian Appenines, the Serra Dolcedorme (2.267 m a.s.l.) (not visited by us). We hope our studies inspire other arachnologists to visit the southern parts of Italy, where still is much to learn and discover. Nieuwsbrief SPINED 38 9 Fig. 1. Map showing collection localities.
