Tetralonia alticincta (LEPELETIER, 1841), die Flohkraut-Langhornbiene, konnte im Jahr 2019 in Aachen (Nordrhein-Westfalen) nachgewiesen werden. Der letzte Nachweis dieser Art stammt vom Kaiserstuhl, Baden-Württemberg, und liegt über 90 Jahre zurück (STROHM 1925). Verschiedene Möglichkeiten zur Herkunft des Individuums und die Gefährdungssituation d...
Misumena bicolor Simon, 1875, an enigmatic species known only from the male holotype collected on Corsica (France), has remained elusive since its initial description. In this study, we report new occurrences of M. bicolor from Sardinia (Italy) and Bavaria (Germany) based on male material, considerably expanding its known distribution. Employing an...
In the present study, we investigate how spiders can be used to assess the effectiveness of restoring mesic grasslands on former urban lawns. We compile and analyze a comprehensive dataset, including both past and current data, focusing on the Aachen region. By systematically examining this data, we identify various indicators using different analy...
The ARAMOB data repository compiles meticulously curated spider community datasets from systematical collections, ensuring a high standard of data quality. These datasets are enriched with crucial methodological data that enable the datasets to be aligned in time and space, facilitating data synthesis across studies, respectively, collections. To s...

Diplocephalus graecus (O. Pickard-Cambridge, 1873), a very common holomediterranean species, has undergone a remark-
able range expansion in the western Palaearctic region over the past two decades. Recently, the species was found for the first time in Germany in a field near Aachen (North Rhine-Westphalia). We traced the potential dispersal path o...
New species records for the Rhineland-Palatinate (Germany) from studies in forests from the Eastern Eifel region are reported. Ischyropsalis hellwigii hellwigii (Panzer, 1794) is recorded for the first time west of the river Rhine. Other remarkable species are Oreonetides quadridentatus (Wunderlich, 1972), to date known from only ten other localiti...
