New data on the spiders (Arachnida: Araneae) of Dagestan, Russia

The study presents a list of 93 spider species collected in Dagestan, 12 of which are new records for the region. The following six species are illustrated: Aelurillus laniger Logunov & Marusik, 2000, Arctosa personata (L. Koch, 1872), Arctosa ravida Ponomarev, 2007, Clubiona caucasica Mikhailov & Otto, 2017 and Cyclosa algerica Simon, 1885. I also provide photographs of live specimens for eight species, taken in their natural habitat, and present the first published photograph of the web of Atypus muralis Bertkau, 1890. Two species, Aulonia kratochvili Dunin, Buchar & Absolon, 1986 and Cyclosa algerica, are recorded for Russia for the first time; the former species is redescribed. A new species, Paracedicus ponomarevi sp. n. (Desidae), is described based on a female specimen. The family Desidae is reported from Russia for the first time. The current state of knowledge on the spider fauna of Dagestan and prospects for future research is discussed.
