Erigoninae, new species, P. luteus sp. nov., Ukraine
Abstract
New data on the genus Panamomops are presented from Ukraine. Panamomops inconspicuus (Miller & Valešová, 1964) is reported for the first time. A new species, Panamomops luteus sp. nov., is described based on both sexes.
Aus der Ukraine werden neue Nachweise der Gattung Panamomops präsentiert. Panamomops inconspicuus (Miller & Valešová, 1964) wird erstmals nachgewiesen. Eine neue Art, Panamomops luteus sp. nov., wird anhand beider Geschlechter beschrieben.
First record of Macrothele calpeiana (Araneae: Macrothelidae) in Austria
Erstnachweis von Macrothele calpeiana (Araneae: Macrothelidae) für Österreich
introduced species, molecular species identification
Abstract
Macrothele calpeiana (Walckenaer, 1805) (Macrothelidae) is reported for the first time in Austria (Untermeierhof in Lower Austria). Identification to species level was performed by molecular methods (DNA barcoding).
Die Andalusische Trichternetzspinne Macrothele calpeiana (Walckenaer, 1805) (Macrothelidae) wurde das erste Mal für Österreich in Untermeierhof in Niederösterreich nachgewiesen. Die Bestimmung auf Artniveau erfolgte mittels molekularer Methoden (DNA Barcoding).
Epigeic spiders (Arachnida: Araneae) in urban green spaces in Westphalia
Araneae, Germany, North Rhine-Westphalia, spider assemblages, urban biotic homogenization, urban green spaces
Abstract
This dataset was generated to assess urban biotic homogenization in epigeic spider (Arachnida: Araneae) communities across urban public parks in the Münsterland region, North Rhine-Westphalia, Germany. Spiders were sampled in 15 cities using standardized pitfall traps in 30 plots (two plots per city). Sampling sites consisted of managed lawns interspersed with scattered trees, shrubs, and footpaths. Pitfall traps were active from 6. May to 17. Jun. 2025 and were emptied every 21 days. Four traps per plot were installed in areas with minimal direct disturbance, resulting in a total of 120 traps. Due to occasional disturbance or trap loss, the number of functioning traps per plot was sometimes reduced. In total, 2599 adult individuals and 418 juveniles were collected, representing 90 species from 22 families. All recorded species are classified as not endangered according to the Red List of North Rhine-Westphalia. The dataset provides a basis for analysing beta diversity and species composition across urban green spaces and can be used to test the urban biotic homogenization hypothesis.
New records of Segestria florentina from Germany with observations on somatic and genitalic differences in juveniles and adults compared to S. bavarica (Araneae: Segestriidae)
Neue Nachweise der Mächtigen Fischernetzspinne Segestria florentina aus Deutschland mit Beschreibung von somatischen und genitalen diagnostischen Merkmalen bei Juvenilen und Adulten zu S. bavarica (Araneae: Segestriidae)
faunistics, taxonomy, tubeweb spider
Abstract
New records of the large tube web spider Segestria florentina (Rossi, 1790) from Essen in North Rhine-Westphalia in Germany are presented. Genital characteristics of specimens from Germany are compared with those of the native Segestria bavarica C. L. Koch, 1843. For differentiation of juveniles of the two species, characteristics of the leg spination and opisthosomal colouration are described.
Neue Funde von Segestria florentina (Rossi, 1790) werden aus Essen in Nordrhein-Westfalen berichtet. Genitale Merkmale der Art bei Tieren aus Deutschland werden denen heimischer Segestria bavarica C. L. Koch, 1843 gegenübergestellt. Zur Unterscheidung der beiden Arten auch im Juvenilstadium werden charakteristische Merkmale der Beinbestachelung und Opisthosoma-Färbung dargestellt.
