In the Monte Pisano area (Tuscany, central Italy), spiders were collected within two research projects during three years (2010, 2013, 2014). Olive groves and adjacent semi-natural habitats (wood and Mediterranean garrigue) were investigated with three sampling methods (pitfall trapping, beating at branches and hand collection in the canopy). A total of 148 species was identified. The ground spider (Gnaphosidae) Zelotes fulvaster (Simon, 1878) was recorded for the first time in Italy.

During a scientific internship in a mountainous area near Agadir, several caves were prospected; the sampled material included several spider species. Morphological and taxonomical analysis revealed two new species to science: an anophthalmic troglobiont species, Agraecina agadirensisspec. nov. (description based on three females) and a new member of the genus Steatoda in the Mediterranean region, Steatoda ifricolaspec. nov. (description based on both sexes). Diagnoses, drawings and photos are presented.

Seven female specimens of Eukoenenia florenciae (Rucker, 1903) were collected in greenhouses of the Munich Botanical Garden (Munich, Germany). Morphological determination is supported by sequencing and comparison of the 18S and 28S genes in BLAST. This is the first record of the arachnid order Palpigradi in Germany.

The arachnological collections of the Museo Civico di Storia Naturale of Verona, Italy, contains roughly 20000 vials, including approximately 2000 species of Araneae and other Arachnida from all over the world. Within the collection, type material represents an important proportion with a count of more than 373 type series. All samples are distributed within four main collections: Brignoli, di Caporiacco, Museo Zangheri and‘Generale'. A further collection of 99% ethanol-preserved samples for molecular analysis is currently under preparation. A detailed list of all the arachnological type material stored in the museum is provided.

The presence of Silometopus curtus (Simon, 1881) in Hungary is confirmed. Comparative photos of male and female of S. curtus and the closely related species S. ambiguus (O. Pickard-Cambridge, 1906) are presented. The phenology of S. curtus in Hungary is described and its patchy distribution is discussed.

Philodromus musterispec. nov., a member of the Philodromus aureolus group from the Mediterranean coast of south-west Turkey, is described from a male specimen. Photos, drawings, diagnosis and a complement to the determination key are provided.

The crab spider Xysticus brevidentatusWunderlich, 1995 is one of the most rarely recorded thomisids in Europe. A new record of this species from Bosnia and Herzegovina, the northernmost of its currently known distribution, is presented together with first photographic illustrations of both adult sexes and the diagnostic genital characteristics. The paper also gives information on the habitat for the first time and discusses the known records of the species on the Balkan Peninsula and in southern Italy. The latter record needs further verification due to the recently revealed presence of the highly similar Xysticus macedonicus Šilhavý, 1944 in the same region.

Philodromus splendensspec. nov. is described from both sexes and tentatively placed in Philodromus Walckenaer, 1826. Its relationships are briefly discussed. The number of reported spider species from Bulgaria is thus raised to 1046.

Two spider species, Clubiona pseudoneglectaWunderlich, 1994 and Paratrachelas maculatus (Thorell, 1875), have been recorded for the first time in Slovakia. One male and five females of C. pseudoneglecta were collected at three sites in the Danube Plain. Two females of P. maculatus were found in the parks of the town of Galanta. Photos of the habitus and genitalia, an overview of the current distribution and habitat preferences are presented.

Records of the short-tailed whipscorpion Stenochrus portoricensisChamberlin, 1922 (Schizomida: Hubbardiidae) from greenhouses in North Rhine-Westphalia are presented together with detailed diagnostic drawings of the species. Stenochrus portoricensis is native to southern North America and the Caribbean and is the most commonly introduced species of Schizomida in Europe. In Germany the species has only been recorded previously from Hesse. A review of all introduced schizomid records in Europe reveals that S. portoricensis is currently the only species that occupies habitats outside of greenhouses.

Data on the spider fauna from the forest ecosystems of the Děvín National Nature Reserve (South Moravia, Czech Republic) are presented. The research was carried out on 15 randomly chosen research plots in oak-hornbeam forest stands within different management regimes. Spider sampling was done by pitfall trapping from May to October 2016. Overall, 3683 adult spiders belonging to 22 families, 70 genera and 116 species were collected. The families Linyphiidae, Lycosidae, Gnaphosidae and Thomisidae exhibited high species richness. The most abundant species were Pardosa lugubris (Walckenaer, 1802) and Trochosa terricola Thorell, 1856. Faunistically remarkable species were Atypus piceus (Sulzer, 1776), Drassyllus villicus (Thorell, 1875), Gnaphosa montana (L. Koch, 1866), Panamomops affinis Miller & Kratochvíl, 1939 and Walckenaeria monoceros (Wider, 1834). The record of Gnaphosa montana is one of the first accounts of this psychrophilic spider from European lowlands. Of the identified species, 23 are listed in the Red List of Threatened Species in the Czech Republic (EN – 1 species, VU – 12 species, LC – 10 species).

Die amerikanische Zwergspinne Erigone dentosa O. Pickard-Cambridge, 1894, wurde in einer Gärtnerei in der Altstadt von Zeitz (Sachsen-Anhalt) gefunden. Dabei handelt es sich um den Erstnachweis dieser Spezies für die Fauna Deutschlands. Der Autor beobachtet die Spinnenfauna dieses Gartenbaubetriebes durch unregelmäßige Probennahmen seit etwa 20 Jahren. Erigone dentosa wurde erstmals im Februar 2020 per Handfang nachgewiesen, bis September erhöhte sich die Zahl auf insgesamt 12 Exemplare. Es ist nicht bekannt, auf welchem Weg diese Spinnenart die Gärtnerei erreichte. Unter den nachgewiesenen 68 Spinnen- und drei Weberknechtarten gelten sieben als Neozoa.
