Key words: Aranei, fauna, Taganrog Bay, delta of the Don River. Резюме. На побережье Таганрогского залива Азовского моря и в дельте Дона выявлено 350 видов пауков из 28 семейств. В дельте обнаружен 281 вид из 25 семейств, на побережье залива -246 видов из 25 семейств. Общность фауны дельты и побережья составляет 51%. В видовом отношении преобладают Linyphiidae (64 вида), причем большая часть видов этого семейства приурочена к дельте. Gnaphosidae (47 видов) и Salticidae (43 вида) распределены по побережью и в дельте более или менее равномерно. На долю этих трех семейств приходится 44% от всех зарегистрированных видов. Впервые в фауне России отмечается Baryphyma maritimum (Crocker et Parker, 1970). Новыми для фауны Ростовской области оказались Larinia jeskovi Marusik, 1986, Clubiona diversa O. Pickard-Cambridge, 1862, Araeoncus crassiceps (Westring, 1861), Pardosa femoralis Simon, 1876, Pulchellodromus ruficapillus (Simon, 1885), Pachygnatha clerckoides Wunderlich, 1985, Enoplognatha caricis (Fickert, 1876). Для вида Zelotes manytchensis (Ponomarev et Tsvetkov, 2006) установлена первоначальная комбинация Trachyzelotes manytchensis Ponomarev et Tsvetkov, 2006, comb. resurr.Abstract. This paper is a continuation of our publications on the spider fauna of coastal areas of dryland Ponto-Caspian region. We used the material collected in the coast of the Taganrog Bay (the Sea of Azov) on the territory of Donetsk Region (Mariupol, Novoazovskiy and Pershotravnevyi Districts) and Rostov Region (Taganrog, Azovskiy and Neklinovskiy Districts) as well as in the delta of the Don River -2015. In addition, the previous publications about the spider fauna of this part of the Ponto-Caspian region were critically reviewed. Three hundred fifty species of spiders from 28 families are registered on the Taganrog Bay coast (the Sea of Azov) and in the delta of the Don River; 281 species of 25 families were found in the delta and 246 species from 25 families were collected around Taganrog Bay. The faunal similarity of the delta and the coast is 51%. Linyphiidae is the most diverse family which includes 64 species distributed mainly in the delta. Gnaphosidae (47 species) and Salticidae (43 species) are uniformely distributed both on the sea coast and the Don River delta. These three families include 44% of all recorded species. Baryphyma maritimum (Crocker et Parker, 1970) is recorded for Russia for the first time.

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

“…Muster & Thaler [2004] characterized this species as having a widely Mediterranean (holomediterranean) range. The records of P. longipalis from the coast of Azov Sea and the delta of Volga River [Ponomarev, 2011;Ponomarev et al, 2016] do not contradict to this range type. Yet, the findings in Moscow Area [Pokrovskiy, 1925] extend the northern limit of species' range far beyond the Mediterranean region, and, in our opinion, should be considered erroneous.…”

“…Area. Described form Kalmykia [Ponomarev, 1979], and then has been recorded from the shores of Black and Azov Seas, northern Dagestan (Russia) and Azerbaijan [Ponomarev, Tsvetkov, 2004;Mikhailov, 2013;Polchaninova, Prokopenko, 2013;Ponomarev et al, 2011Ponomarev et al, , 2016Ponomarev, 2017]. Due to insufficient knowledge of this species, figures of the epigyne (Figs 10-11) based on the female from the Astrakhan nature reserve has been provided.…”

“…This species is distributed in southern Europe, Azerbaijan and Iran [WSC, 2018]. In Russia, the species was hitherto recorded from Moscow Area [Pokrovskiy, 1925], the coast of the Taganrog Gulf [Ponomarev, 2011] and the delta of Don River [Ponomarev et al, 2016]. Muster & Thaler [2004] characterized this species as having a widely Mediterranean (holomediterranean) range.…”

New species and new records of ant-eating spiders from Mediterranean Europe (Araneae: Zodariidae)

“…In his revision of the genus, Bosmans (1997) gave further records in NE Spain, Italy, Belgium, Germany, Switzerland, Hungary, the Czech Republic and Slovakia. Since then, the species expanded its range to Danmark (Scharff et al 2007), Poland (Rozwałka & Gosik 2006), Slovenia (Kuralt & Kostanjšek, 2016), South-East Ukraine (Ponomarev et al 2016) and Southern European Russia (Ponomarev et al 2017).…”

Spiders (Arachnida: Aranei) of Stavropol Province, Russia

“…COMMENTS. This rare species was described from Kerch Peninsula of the Crimea [Kovblyuk, Tuneva, 2009] and was then recorded from the coast of Taganrog Bay [Ponomarev et al, 2016].…”
