This book consists of fifteen papers (considered below as Chapters) on fossil and extant arachnids, mostly spiders. Most papers are written by the editor, two papers in cooperation with Peter Jäger and with Søren Toft, and a single one by Peter Jäger. Chapters 1 and 2 are identification keys to the European genera of the families Zodariidae and Corinnidae, respectively.
Mit dem achten Band der von Jörg Wunderlich herausgegebenen Serie „Beiträge zur Araneologie“ liegt endlich ein lange überfälliges Werk vor: Ein Bestimmungsschlüssel aller europäischen Familien der Webspinnen, wobei auch die fossilen Taxa (v.a. aus Baltischem Bernstein) berücksichtigt werden.
In the ”Checklist of the spiders of Central Europe” 945 species are listed for Switzerland. During the last few years numerous species have been found which represent new records for Switzerland and that, at least partly, have already been published. This 4th appendix to the catalogue of Swiss spiders presents fourteen species recorded for the first time in Switzerland: Carniella brignolii Thaler & Steinberger, 1988, Theridion cinereum Thorell, 1875, Diplocephalus foraminifer (O. P.-Cambridge, 1875), Panamomops affinis Miller & Kratochvíl, 1939, Troxochrota scabra Kulczyński, 1894, Pardosa fulvipes (Collett, 1876), P. sphagnicola (Dahl, 1908), Hahnia microphthalma Snazell & Duffey, 1980, Archaeodictyna consecuta (O. P.-Cambridge, 1872), Brommella falcigera (Balogh, 1935), Cheiracanthium campestre Lohmander, 1944, Drassodex drescoi Hervé, Roberts & Murphy, 2009, Thanatus firmetorum Muster & Thaler, 2003 and Xysticus viduus Kulczyński, 1898. Thirteen further species are presented that were already published elsewhere. The current number of species in Switzerland is thus 972. As special curiosities, five species are presented that will not yet be entered into the checklist but nevertheless may happen to be found in human surroundings.
The manuscript name Chelifer longimanus Kollar, 1848, most often cited as Obisium longimanum Kollar, was first introduced in a note by Kollar (1848) that has been overlooked in the taxonomic literature on pseudoscorpions. No description or indication has been associated with this name, which is therefore a nomen nudum. It corresponds to the valid pseudoscorpion species Neobisium spelaeum (Schiödte, 1847), having been found at one of the type localities of the latter (Postojna Cave, Slovenia). Two specimens originally identified as O. longimanum (probably by V. Kollar) are present in the collections of the Naturhistorisches Museum Wien.
Spiders from the Tirana district of Albania were investigated. Currently, 78 species from 24 families and a collection of 400 specimens from January to August 2010 were recorded for Tirana. A total of 32 new records for the Albanian fauna are included in the present paper. Agraecina lineata (Simon, 1878) is the first record for the Balkan Peninsula. Saitis graecus Kulczyński, 1905 was known before only from Greece and Bulgaria. Presently, 373 spider species are known for Albania.
Erstnachweise von Paratrachelas maculatus in Österreich und Deutschland (Araneae, Corinnidae)
(2012)
Three adult females of Paratrachelas maculatus (Thorell, 1875) were found inside a house in the south of Vienna, in a cellar in Cologne and in a house in Rüsselsheim. Additional notes on diet in captivity are presented.
We found the ichneumonid Polysphincta rufipes Gravenhorst, 1829 (tribus Polysphinctini) to be a koinobiont parasitoid of two species of araneid orb-weavers, Larinioides sclopetarius and Zygiella x-notata, in Central Europe. Some notes on the biology of P. rufipes are given, based on observations both in the field and in the laboratory. The wasps directly attack non-adult spiders sitting in the hubs of their webs. Parasitized spiders could be found from, at least, August to early December. The duration of the development of the wasp larvae, including the pupal stage, is about two months. It seems conceivable that at the end of the larval stage the larva somehow manipulates its host spider; i.e. the spider is forced to enter its retreat – a safe place where the larva can kill the host, complete its development and spin a cocoon for pupation (pupa libera).
