A female of the dwarf sheet spider Hahnia picta Kulczyński, 1897 was found in an old castle park in Berlin (Germany). All published records as well as unpublished records from Austria are listed and mapped. This species is rarely recorded. Its distribution is confined to Europe. H. picta seems to live exclusively under the bark of old deciduous trees.
Carniella brignolii Thaler & Steinberger, 1988 was first described based on a male from Austria and still belongs to the rare, scarcely studied species. Based on material from Germany and Switzerland the hitherto unknown female now can be assigned and presented. In this context a new synonymy is also proposed: The cave-dwelling, troglomorphic C. mihaili (Georgescu, 1989) from Romania, originally established as new genus Marianana, is synonymised with C. brignolii.
Faunistic spider collections in the Museum für Naturkunde Berlin: The collection of Erich Hesse
(2012)
The ‘Hesse collection’ of spiders (Araneae) and harvestmen (Opiliones) in the Museum für Naturkunde Berlin is documented. Biographical notes on Erich Hesse – a former arachnid curator at the museum (1921–1940) – are provided. The ‘Hesse collection’ was actually put together by other workers, and can be broadly divided into two parts. One comes from Bielinek (= Bellinchen) on the Polish side of the Oder Valley (West Pommerania); now part of the ‘Unteres Odertal’ National Park. This Bielinek material includes notable records of Heriaeus oblongus Simon, 1918 and Gibbaranea ullrichi (Hahn, 1835). The other part of the collection comes from Colbitz-Letzlinger Heide in Saxony-Anhalt, Germany. Notable here are Pistius truncatus (Pallas, 1772) and Philodromus buchari Kubcová, 2004; the latter representing the first record of this species for Saxony-Anhalt.
The rare money spider Walckenaeria simplex Chyzer, 1894 was found in 2007 near the city of Meißen (Germany) on a rock overlooking the river Elbe. This is the northernmost occurrence of the species. W. simplex is distributed from Central to South Eastern Europe. The species is thermophilous and prefers wooded slopes with a southern exposition.
A glimpse of the tropics : spiders (Araneae) in the greenhouses of the Botanic Garden Berlin-Dahlem
(2008)
In a survey of the spider fauna in greenhouses of the Botanic Garden Berlin-Dahlem, 30 spider species were recorded. Two species are new to Europe: Theotima minutissima (Petrunkevitch, 1929) and Heteroonops spinimanus (Simon, 1891). T. minutissima is the first member of the family Ochyroceratidae reported from Europe. Oecobius navus Blackwall, 1859 is new to Central Europe. Triaeris stenaspis Simon, 1891, is recorded from Germany for the first time. Zodarion italicum (Canestrini, 1868) is new to eastern Germany. Despite the discovery of some species previously unknown to Germany, the spider fauna in the Botanic Garden consisted mainly of wellknown synanthropic species and common inhabitants of greenhouses. Several alien spiders recently found in greenhouses, garden centers and houses were not recorded in the Botanic Garden. The species composition of the exotic spider fauna in greenhouses seems to depend chiefly on the specific modes of acquisition of plants and plant substrate.
