In the World Spider Catalog (WSC 2017) the formerly overlooked species Zelotes turcicus Seyyar, Demir & Aktaş, 2010 was recently added. Thus Zelotes turcicus Wunderlich, 2011 is a primary homonym and requires a new name. The author informed Jörg Wunderlich who approved the present author to carry out this formal renaming (without suggesting a new name): for Zelotes turcicus Wunderlich, 2011 the replacement name Zelotes wunderlichi nomen novum is herewith proposed.

Charinus ioanniticus is known from the Eastern Mediterranean (Greece, Turkey, Israel and Egypt) from 10 localities and Musicodamon atlanteus is known from the Maghreb (Morocco, Algeria) from three localities. All records are mapped.

Farmland is a major land cover type in Europe and Africa and provides habitat for numerous species. The severe decline in farmland biodiversity of the last decades has been attributed to changes in farming practices, and organic and low‐input farming are assumed to mitigate detrimental effects of agricultural intensification on biodiversity. Since the farm enterprise is the primary unit of agricultural decision making, management‐related effects at the field scale need to be assessed at the farm level. Therefore, in this study, data were collected on habitat characteristics, vascular plant, earthworm, spider, and bee communities and on the corresponding agricultural management in 237 farms in 13 European and two African regions. In 15 environmental and agricultural homogeneous regions, 6–20 farms with the same farm type (e.g., arable crops, grassland, or specific permanent crops) were selected. If available, an equal number of organic and non‐organic farms were randomly selected. Al...

In the context of the Hessian strict forest program, the reserve Hasenblick was set aside from forest management in 1988. The program aims to document the faunas of forest reserves in unprecedented detail, using a set of many different sampling methods. Here data on ground dwelling spiders and beetles that were sampled with pitfall traps in 2000 and 2001 and again in 2012 and 2013 are analyzed to assess temporal changes. In light of putative insect declines, we hypothesized a significant decrease in abundance, biomass, diversity, and trait composition of the arthropod communities. No substantial changes in community trait composition were observed in any species group. Abundance, biomass, and functional diversity of beetles and spiders were higher in the second survey, with exception of the beetle biomass, when Anoplotrupes stercorosus was excluded, and the functional diversity of spiders showed only a tendency to be higher in the second survey. Additionally, the extrapolated number...

Macroecologists seek to identify drivers of community turnover ( β -diversity) through broad spatial scales. However, the influence of local habitat features in driving broad-scale β -diversity patterns remains largely untested, owing to the objective challenges of associating local-scale variables to continental-framed datasets. We examined the relative contribution of local- versus broad-scale drivers of continental β -diversity patterns, using a uniquely suited dataset of cave-dwelling spider communities across Europe (35–70° latitude). Generalized dissimilarity modelling showed that geographical distance, mean annual temperature and size of the karst area in which caves occurred drove most of β -diversity, with differential contributions of each factor according to the level of subterranean specialization. Highly specialized communities were mostly influenced by geographical distance, while less specialized communities were mostly driven by mean annual temperature. Conversely, l...

Modern taxonomy and systematics profit from an invaluable tool that has been developed in the course of more than a century by intense discussions and negotiations of generations of zoologists and palaeontologists: The International Code of Zoological Nomenclature (ICZN 1999, 2012). The main goal of the Code is “to promote stability and universality in the scientific names of animals and to ensure that the name of each taxon is unique and distinct” (Melville 1995, ICZN 1999: 2). The provisions of the Code are generally accepted and thoroughly applied by the scientific community. Exceptions, such as the one described below, are very rare.

Abstract Under natural conditions beech forest would be the most widespread habitat in Central Europe. Therefore the knowledge of this vegetation type, including the animal communities dwelling there, as well as the mechanisms forming these communities are of high interest for biodiversity research and conservation in Central Europe. However, historically, Central European beech forests were thought to harbor only relatively few species. Here, faunistic data of five beech forest reserves, which were generated as part of the Hessian strict forest reserves program, are analyzed to investigate diversity patterns of Hessian beech forests of low mountain ranges. We focus on species-level data from six organism groups: Aculeata, Araneae, Coleoptera, Heteroptera, Lumbricidae, and Macrolepidoptera. We show that with 2552 forest-dwelling species from these organism groups an unexpectedly high number of species was found in Hessian beech forests, and that a higher species richness can be expected in these groups. Observed species diversity ranges from 1245 to 1556 forest dwelling species in the five individual forest reserves. Overall, 36 % of the forest dwelling species of the considered species groups known from Germany were found with all applied methods in the forest reserves. Different forest reserves share 40–50 % of the species, representing 50–70 % of the species of the individual reserves, indicating high levels of regional and habitat-structure based differentiation. Only 21 % of the species are found in all five reserves. The low percentage of species found in all five reserves is, in addition to differing local conditions, probably a result of the communities being composed of few highly abundant and many rare species, leading to a high percentage of species only found by chance in our surveys. We also observe differences in community heterogeneity among the five reserves. Patterns differ between organism groups, clearly indicating that a focus on single taxa or a single indicator group falls short of revealing meaningful patterns. In spider communities, beta diversity is linked to the spatial distance between traps. In other organism groups community heterogeneity within reserves rather depends on structural heterogeneity. Species richness was associated with percentage of reserve area not covered with the most dominant habitat type, the deadwood amount, and with survey year. Being the potential natural vegetation of Germany and considering the unexpectedly high diversity of their associated fauna, beech forests bear a great conservation value. However, their widespread occurrence and dominance is likely to push them out of focus of conservation efforts. Yet protecting diverse and richly structured beech forests can contribute greatly to preserving the native arthropod fauna and should play a central role in biodiversity conservation efforts in Central Europe.

The family Theraphosidae is the most speciose in the infraorder Mygalomorphae Pocock, 1892 with over one thousand described species (World Spider Catalog 2021). The taxonomy of the group has been subjected to considerable attention in modern times, with a focus on delineation based predominantly on genital organ and stridulatory organ morphology which has shown promise, both alongside molecular methods (where possible) and as a stand-alone line of evidence, in stabilising the group (e.g. Hamilton et al. 2016; Fabiano-da-Silva et al. 2020; see also Sherwood 2020). The predominant reference to the family is as Theraphosidae Thorell, 1870 with almost as many references to Theraphosidae Thorell, 1869. This non-congruence of dates is because Tord Tamerlan Teodor Thorell (1830-1901) had his important work On European Spiders published in two parts during its publication by the Royal Society of Upsala in its journal Nova Acta Regiae Societatis Scientiarum Upsaliensis.
