Annotated list of spiders of the Volgograd agglomeration

The article presents an annotated list of spiders based on their systematic position on the territory of the Volgograd agglomeration. The need to conduct such a study is emphasized by the exceptionally poor knowledge of the current state of the Aranei order in the Volgograd region. There have been no systematic studies for more than fifty years, the available data is scarce and fragmentary, and there is no description of the species living in various biotopes. Studies of araneofauna were carried out in the Volgograd region in the period 2003-2020. The material was collected largely using Barber soil entomological traps with a fixing liquid (6 % acetic acid solution) with a diameter of 100 mm. As part of the study of the seasonal dynamics of the species composition of spiders in various biotopes of the Volgograd agglomeration, 17 series of traps were laid at five test sites. The traps were installed in quantities of 8-10 pieces at a distance of 5 m from each other, were not covered, were exposed throughout the warm season (April-October), and checked once every 7 days. The material was fixed in a 75 % ethyl alcohol solution. Species identification was carried out using guides and was confirmed by the leading researcher of the Southern Scientific Center of the Russian Academy of Sciences, Candidate of Sciences (Biology), A.V. Ponomarev. Field research involved 388,776 trap days; a total of 9,395 spiders were captured.
