A schizomid, Stenochrus portoricensis Chamberlin, 1922 (family Hubbardiidae), was collected in a greenhouse in Brno. This is the first discovery of a schizomid from the Czech Republic.

The first record of the very rare linyphiid spider Ceraticelus bulbosus (Emerton, 1882) from Germany is presented. Furthermore records of Agroeca dentigera, Agyneta arietans, Bathyphantes setiger, Brommella falcigera, Crustulina sticta, Erigone dentigera, Meioneta mossica, and Pardosa morosa and other rare spiders are reported.

The present study provides a robust data set for ecological planning and conservation of dry ecosystems in western Germany in general and North Rhine-Westphalia in particular. We summarised all available data from recent publications that dealt with spiders in dry ecosystems of North Rhine-Westphalia. Additionally, so far unpublished results of a detailed investigation regarding spiders in sand habitats of the Westphalian Bay that was conducted between 2006 and 2008 are presented. The analysis focussed on the habitat types according to Annex I of the EU Habitats Directive and related habitats. The investigation areas were scattered in the federal state of North Rhine-Westphalia. The data set comprised a total of 84436 individuals from 371 species and 28 families. Overall, an endangerment status is assigned to 68 species. Of these, 12 spiders are in imminent danger of becoming extinct. Two species, Erigonoplus globipes and Meioneta simplicitarsis, are believed to be extinct in North Rhine-Westphalia. Seven species (Dictyna major, Mastigusa arietina, Micaria formicaria, Styloctetor romanus, Thanatus striatus, Theridion uhligi and Xysticus ferrugineus) are new to the arachnofauna of North Rhine-Westphalia.

Five species were recorded for the first time in Schleswig-Holstein, northern Germany: Psilochorus simoni (Berland, 1911) (Pholcidae), Ero aphana (Walckenaer, 1802) (Mimetidae), Panamomops mengei Simon, 1926 (Linyphiidae), Archaeodictyna consecuta (O. P.-Cambridge, 1872) (Dictynidae). Nigma walckenaeri (Roewer, 1951) (Dictynidae) is not considered to be rare, but a record is published from this region for the first time. A new northernmost distribution point for Theridion boesenbergi Strand, 1914 (Theridiidae) was recorded. Notes on other species rarely found in Schleswig-Holstein and Lower Saxony are also provided.

obituary, Friedrich Wallenstein. Link for German translation of Fabre: arages.de/files/Wallenstein_Fabre_2009.pdf

Data and a drawing of the epigyne of Phoneutria boliviensis (F.O. Pickard-Cambridge, 1897), recently recorded from Germany, are presented. The specimen was introduced with cargo (bananas) from Brazil. Characters of the single female are illustrated to facilitate identification in the future, since in the two recent revisions of the genus no drawing of the epigyne of P. boliviensis was included. Another case of introduction from 1998 of an unidentified subadult Phoneutria specimen, probably P. boliviensis too, with bananas from Ecuador is documented.
