Extensive green roofs are recognised as being a suitable habitat for some specific plants and arthropods that are resistant to very extreme hot and dry conditions. Little is known about spider species visiting and living on green roofs. In 2018 and 2019, 29 green roofs in Basel and four roofs in Aarau (Switzerland) were sampled using pitfall traps during the entire growing season. In the sampling period, 18467 adult spiders were collected and identified into 123 species. Two species were collected for the first time in Switzerland: Erigone dentosa O. Pickard-Cambridge, 1894 and Runcinia grammica (C. L. Koch, 1837). According to the Red List of Germany (and especially Baden-Württemberg), 26 species are of special interest from a nature conservation perspective. On the other hand, four species are alien species (i.e. they originate from other continents), and 14 species are expanding their range northward. Green roofs may therefore harbour endangered species, but there is also the possibility that the newly invading species may become dominant. Only after many years or even decades will it be possible to judge whether green roofs are primarily substitutes for lost habitats or stepping-stones for new invaders.

Five spider species are recorded for the first time from Luxembourg. Their habi-tats are described. New data are presented for another three species. The importance of the former open-cast iron ore quarries of southwestern Luxembourg for thermophilous spiders is emphasised

Improved understanding of lampyrid beetles in Switzerland and observation of Luciola lusitanica Charpentier, 1825 in Geneva (Coleoptera, Lampyridae). – Five species of Lampyridae are present in Switzerland. While Lampyris noctiluca, Lamprohiza splendidula, Phosphaenus hemipterus and Luciola italica have long been known, the presence of Luciola lusitanica is confirmed here for the first time. The recent capture of specimens in Geneva, probably the result of introductions, demonstrates the presence of this species in Switzerland. The distribution of all species of lampyrid beetles in Switzerland, information about their biology and the history of different regional introductions are discussed.

On the value of old collections by amateurs – four spider species new to Switzerland in the Ketterer collection. During the 1960s to 1980s Charles-Emanuel Ketterer collected and identified spiders mostly from Wallis (Switzerland) without almost any contacts to other arachnologists. His collection is documented accurately by a datasheet per sample. Considering the possibilities at that time, the identifications were highly accurate. The 836 samples re-determined cover 249 species. Four of them represent first records for Switzerland: Altella lucida (Simon, 1874), Agyneta suecica Holm, 1950, Neon rayi (Simon, 1875), and Hyptiotes flavidus (Blackwall, 1862). A further nine species would have been first records if Ketterer had published his data at that time.

In the years 2004 to 2017 the author has recorded 25 spider species and one harvestman newly for Schleswig-Holstein. The unpublished records since 2010 are presented for the first time: 2010: Araniella inconspicua (Simon, 1874); 2011: Hahnia ononidum Simon, 1875; 2012: Centromerus incilium (L.

P.-Cambridge, 1871) and the lost harvestman Lacinius horridus (Panzer, 1794); 2015: Cheiracanthium campestre Lohmander, 1944, Improphantes decolor (Westring, 1861), Sibianor larae Logunov, 2001; 2017: Clubiona leucaspis (Simon, 1932). In addition, remarks on endangerment status with respect to earlier records since 2004 are provided.

Zusammenfassung: Begrünte Dachfl ächen können für verschiedene Arten aus Bahnarealen und schotterreichen Ufergebieten einen Ersatzstandort darstellen. In einer Untersuchung der Spinnen-fauna von 16 Bodenstandorten (hauptsächlich naturschutzrelevante Bahnareale) und sechs begrünten Dachfl ächen in Basel (Schweiz) konnten 154 Spinnenarten erfasst werden. 40 davon können als fau-nistische Besonderheiten eingestuft werden, darunter zwei Erstfunde für die Schweiz (Oecobius maculatus, Cicurina japonica). Die faunistischen Besonderheiten wurden nicht nur auf den Boden-fl ächen, sondern in vergleichbarem Masse auch auf den begrünten Dachfl ächen festgestellt. Für die Planung und Gestaltung von begrünten Dachfl ächen zeigt sich, dass mit unterschiedlichen Schicht-stärken eine höhere Vielfalt an Kleinhabitaten entsteht und sich damit auch artenreichere Biozönosen etablieren können. Abstract: Green roofs – ecological characterisation of a new urban habitat type based on a comparison between the spider fauna found on green roofs and in railway sidings with high conservation interest in Basel (Switzerland). Green roofs provide a supplementary habitat for many species which are naturally found in railway sidings or gravelly river banks. In a study of the spider fauna of 16 ground-level sites (mainly railway sidings of high nature conservation value) and six green roofs in Basel, 154 spider species were found, of which 40 were particularly interesting species. Two species (Oecobius maculatus, Cicurina japonica) were recorded for the fi rst time in Switzerland. Compared to the ground-level sites, there was a similar percentage of rare and interesting species on the green roofs. For the planning and design of green roof habitats, it is shown that strata composed of different substrates provide varied microhabitat conditions, and therefore communities with a higher species richness can be established.

Cicada orni Linnaeus, 1758 has long been known in Switzerland. In the cantons of Valais and Ticino, the Mediterranean climate is particularly favorable to the development of the species and some populations reach large sizes. Although no historical records are known from the canton of Geneva, regular sightings have been reported there since 2003, especially in urban zones. Recently, two exuviae were discovered at a locality where C. orni had been previously observed, revealing an emergence site in the canton. We discuss the history of C. orni in Geneva and present several hypotheses concerning the origins and reproduction of the species.

We provide the first overview on spiders living in subterranean habitats in Europe, including the first European subterranean spider checklist. In Europe, there are 486 spider species known to dwell in caves and other subterranean habitats, distributed across 22 families. Despite a few species being able to colonize caves across the whole continent, approximately 90% of the species show a restricted distribution, occurring exclusively in one or two countries. From a biogeographic perspective, southern Europe emerges as the main hot spot of subterranean spider diversity, showing the highest richness of endemic species. Compared to other temperate regions of the world, some families appear to be well represented and other poorly represented (or lacking) in European subterranean habitats. Overall, it appears that the taxonomical knowledge on subterranean spiders in Europe is sufficient, but not evenly distributed. As this checklist represents a useful baseline for advances in this field, we point out specific areas of interest for future research.
