Приводится аннотированный список 325 видов пауков из 31 семейства, выявленных на побережье и островах северной части Каспийского моря. В видовом составе преобладают Gnaphosidae (67 видов), Salticidae (46 видов) и Lycosidae (37 видов). В прибрежной полосе, шириной 20 км от Махачкалы на западе до п-ова Тюб-Караган на востоке, обнаружено 304 вида, на островах -132 вида. Анализ аранеофауны островов Нордовый, Тюлений, Чечень и Кулалы указывает на то, что на каждом из них существует вполне сложившиейя самостоятельный аранеокомплекс. Наблюдаются значительные отличия в составе аранеофауны различных усастков побережья. Abstract. Aim. Araneofauna of Peri-Caspian is fragmentary studied. A literature contains faunistic data for the North-West Caspian and Volga River delta. Several faunistic records and new species were earlier described from the North Caspian. Spiders of Mangyshlak are insufficiently studied. The aim of this wark is summation of available data on araneofauna of coast and islands of North Peri-Caspian with more detailed analisys of spiders of North Caspian islands. Location. Russia: Astrakhan Region, Dagestan, Kalmykia; Kazakhstan: Atyrau and Mangystau Regions. Methods. Investigations include Caspian coastal zone with width about 20 km from Makhachkala (western coast) to Tyub Kurgan (eastern coast) and islands of the Caspian Sea: Nordovyi, Tyuleniy, Chechen, Kulaly. Pitfall traps and manual collection were used during 1975-1985 and 2009-2013. Results and main conclusions. Annotated check-list of 325 species of spiders from 31 families is made for North Caspian coast and islands. Species of the families Gnaphosidae (67 species), Salticidae (46 species) и Lycosidae (37 species) are dominated. Three hundred four species are known from coastal (width 20 km) zone (from Makhachkala to Tyub Kurgan) and 132 species were found on islands. North-Eastern Peri-Caspian coast contents 198 species, Volga River delta -134 species, coast of North and North Eastern Caspian -98 species. Number of species on Caspian islands: Nordovyi -30, Tuleniy -83, Chechen -66, Kulaly -43. Each island has its special araneofauna. There are significant differences in fauna composition of different parts of coastal zone.Ключевые слова: пауки, фауна, cеверная часть Каспия, Россия, Казахстан.

On a small collection of spiders (Aranei) from the Astrakhan Reserve (Russia)

“…[Ponomarev, Tsvetkov, 2006]. Later, it was found in Kalmykia, the vicinity of Ulan Khol [Ponomarev, 2008] and in islands and the coastline of Caspian Sea in northern Dagestan [Ponomarev, Abdurakhmanov, 2014]. As the description of the female was based on a single specimen [Ponomarev, 2008], with its epigyne being illustrated from the ventral view only, in the present paper we have provided additional drawings of the epigyne based on the studied specimen from the Astrakhan Reserve (Figs 1-2).…”
