The study of two species placed in Arctella Holm, 1945, A. lapponica Holm, 1945, and A. subnivalis Ovtchinnikov, 1989, revealed that the latter species belongs to the genus Tricholathys. A new combination is suggested: Tricholathys subnivalis (Ovtchinnikov, 1989) comb. n. The record of Arctella subnivalis from the Northern Caucasus was found to be based on a misidentification and refers to Tricholathys ovtchinnikovi sp. n. All three species are illustrated and described. A new diagnosis is provided for Arctella. Two previously unknown characters were found in the male palp of Arctella and Tricholathys: a large cavity on the mesal side of the tibial apophysis, and a digitiform or spur-like outgrowth on the conductor. http://www.zoobank.org/urn:lsid:zoobank.org:pub:C118569F-2C5C-4204-A1BC-8595B966A914 © 2017 Informa UK Limited, trading as Taylor & Francis Group

Two new species of Bifurcia Saaristo, Tu et Li, 2006 are described based on both sexes from the Maritime Province of Russia: B. oligerae sp.n. and B.Tanasevitchi sp.n. Arcuphantes maritimus Tanasevitch, 2010 is transferred to Bifurcia, and a new combination is established: Bifurcia maritima (Tanasevitch, 2010), comb.n. © ARTHROPODA SELECTA, 2016.

Three species of Xerolycosa: X. nemoralis (Westring, 1861), X. miniata (C.L. Koch, 1834) and X. mongolica (Schenkel, 1963), occurring in the Palaearctic Region are surveyed, illustrated and redescribed. Arctosa mongolica Schenkel, 1963 is removed from synonymy with X. nemoralis and transferred to Xerolycosa, and the new combination Xerolycosa mongolica (Schenkel, 1963) comb. n. is established. One new synonymy, Xerolycosa undulata Chen, Song et Kim, 1998 syn. n. from Heilongjiang = X. mongolica (Schenkel, 1963), is proposed. In addition, one more new combination is established, Trochosa pelengena (Roewer, 1960) comb. n., ex Xerolycosa. © Yuri M. Marusik et al.

Fifty-three species of spiders and one species of harvestmen were found in the previously unstudied Gydansky Peninsula, northwestern Siberia. Distribution for each species is given. Records of certain species are of a special interest: Xysticus viduus (the northernmost locality in its range), Crosbylonia borealis (the westernmost), Oreoneta eskovi (the northernmost and the westernmost), Clubiona norvegica (the easternmost in Asia), Pachygnatha listen, Helophora insignis and Mitopus morio (the northernmost in Asia) and Oreoneta leviceps (the southernmost in the Palaearctic). Three species, Oreoneta eskovi, Pardosa oljunae and Thaleria orientalis, are endemics of West Siberia. About two-thirds of the species are either circum-Holarctic or trans-Palaearctic. © Entomologica Fennica.

Zoology in the Middle East | Year: 2014

This paper reports seven species found in Shirabad Cave located in the western part of Golestan Province and two species found nearby. Three families: Anyphaenidae, Segestriidae and Theridiosomatidae, and one species, Metellina merianae (Scopoli, 1763) are recorded from Iran for the first time. Two species are described as new: Tegenaria zamanii Marusik & Omelko, sp.n. (♀) and Segestria mirshamsii Marusik & Omelko, sp.n. (♀). Four species: Lepthyphantes iranicus Saaristo & Tanasevitch, 1996, Metellina merianae, Octonoba yesoensis (Saito, 1934) and Pholcus sp. are illustrated. Uloborus georgicus Mcheidze, 1997 from Eastern Georgia is synonymized with Octonoba yesoensis. The distribution of all species treated in the paper is briefly discussed, with emphasis on the easternmost records. © 2014 Taylor & Francis.

Spiders belonging to Pirata from the Russian Far East have been surveyed and 14 species are illustrated. Morphological analysis of the northern Holarctic species of Pirata revealed that the genus Piratula can be removed from synonymy with Pirata. New diagnoses are provided for the two genera. Species and genus specific characters were surveyed. Twenty-five species occurring in the northern Holarctic are transferred into Piratula and 22 new combinations are established: Piratula hygrophila (Thorell, 1872), P. borea (Tanaka, 1974) comb.n., P. canadensis (Don-dale & Redner, 1981) comb.n., P. cantralli (Wallace & Exline, 1978) comb.n., P. clercki (Bosenberg & Strand, 1906) comb.n., P. denticulata (Liu, 1987) comb.n., P. gigantea (Gertsch, 1934) comb.n., P. hiroshii (Tanaka, 1986) comb.n., P. hokkaidensis (Tanaka, 2003) comb.n., P. hurkai (Buchar, 1966) comb.n., P. insu-laris (Emerton, 1885) comb.n., P. iriomotensis (Tanaka, 1989) comb.n., P. knorri (Scopoli, 1763), P. lati-tans (Blackwall, 1841), P. longjiangensis (Yan et al., 1997) comb.n., P. meridionalis (Tanaka, 1974) comb.n., P. minuta (Emerton, 1885) comb.n., P. montigena (Liu, 1987) comb.n., P. piratoides (Bosenberg & Strand, 1906) comb.n., P. procurva (Bosenberg & Strand, 1906) comb.n., P. serrulata (Song & Wang, 1984) comb.n., P. tanakai (Brignoli, 1983) comb.n., P. tenuisetacea (Chai, 1987) comb.n., P. yaginumai (Tanaka, 1974) comb.n. and P. yesoensis (Tanaka, 1985) comb.n. It is highly likely that the southern Nearctic genus Sosilaus Simon, 1898 should also be removed from synonymy with Pirata. © 2011ARTHROPODA SELECTA.

Pterotricha loeffleri (Roewer, 1955) is redescribed on the basis of the holotype male from Tehran. A possible female of this species from Bushehr is described for the first time. The potential synonymy of P. loeffleri and P. strandi Spassky, 1936 from Turkmenistan and the unique characters of P. loeffleri are briefly discussed.© ARTHROPODA SELECTA, 2013.

A new species of the extant spider family Anapidae is described from a fossil mature male in Eocene amber from the Baltic region and tentatively assigned to the genus Balticoroma Wunderlich, 2004. Phase contrast X-ray computed micro-tomography was used to reveal important features that were impossible to view using traditional microscopy. Balticoroma wheateri new species is easily diagnosed from all other anapids by having clypeal extensions that run parallel to the ectal surface of the chelicerae and in having the metatarsus of the first leg highly reduced and modified into what is presumably a y-shaped clasping structure. Although only a single extant anapid species occurs in northern Europe, the family was diverse in the Eocene. The discovery of yet another anapid species in Baltic amber supports the idea that Eocene European forests may have been a hotspot of evolution for this family of spiders.

Phrurolithus C.L. Koch, 1839, with 71 named species, is the largest genus of the family Phrurolithidae, which contains 188 species belonging to 14 genera (Platnick 2014). It has an almost exclusively Holarctic distribution: 34 species are known from the Palaearctic, 35 are known from the Nearctic and two species are known from Hispaniola. The genus is rather poorly studied and has never been the subject of wide-scale revision. Almost half of its species are known from a single sex: 23 from females and nine from males. Additionally, 45 species are known from the original description only, and one species has never been illustrated (Platnick 2014).

Three species of Xerolycosa: Xerolycosa nemoralis (Westring, 1861), Xerolycosa miniata (C.L. Koch, 1834) and Xerolycosa mongolica (Schenkel, 1963), occurring in the Palaearctic Region are surveyed, illustrated and redescribed. Arctosa mongolica Schenkel, 1963 is removed from synonymy with Xerolycosa nemoralis and transferred to Xerolycosa, and the new combination Xerolycosa mongolica (Schenkel, 1963) comb. n. is established. One new synonymy, Xerolycosa undulata Chen, Song et Kim, 1998 syn.n. from Heilongjiang = Xerolycosa mongolica (Schenkel, 1963), is proposed. In addition, one more new combination is established, Trochosa pelengena (Roewer, 1960) comb. n., ex Xerolycosa.
