The wolf spider genus Alopecosa Simon, 1885, contains 160 named species (Platnick 2012) and the type species of the genus is A. fabrilis (Clerck, 1757), which is a Palaearctic species like most species in the genus (Platnick 2012). The taxonomic structure of the genus has been studied in two revisions; Lugetti & Tongiorgi (1969) divided 24 species of European Alopecosa into five species groups and Dondale & Redner (1979) divided seven species from North America into three groups. Many species currently in Alopecosa do not appear to be related to the type species; hence the genus is polyphyletic and should be divided into several genera (Marusik & Kovblyuk 2011). Faunistic revisions of Alopecosa have been produced for Italy (Lugetti & Tongiorgi 1969), Romania (Fuhn & Niculescu-Burlacu 1971), North America (Dondale & Redner 1979), China (Song et al. 1999) and Sweden (Almquist 2005). In the Ukraine and European Russia, 18 and 22 species have been reported, respectively (Mikhailov 1997, 2000). Twenty species of Alopecosa have been described since the year 2000 (Platnick 2012), including one from Central Europe (Czech Republic and Slovakia) (Buchar 2001), one from Greece (Buchar 2001), one from Southwestern Russia and six species from Western Kazakhstan (Ponomarev 2007, 2008, 2009).

AbstractThe genus Stomis Clairville is redefined. It includes two subgenera: Neostomis subg. nov. (type-species: Pterostichus termitiformis Van Dyke) with one Nearctic species and Stomis s. str. with 15 Palaearctic species. Eustomis Semenov, previously considered as a distinct genus, is synonymized with Stomis s. str. Description of the genus Stomis and of the two subgenera, as well as a diagnosis and comments on ranking and relationships of the genus, are provided.

Study of the shell features of Givetian and Frasnian spiriferid brachiopods attributed to the genus Cyrtospirifer shows that the type species C. verneuili has micro-ornament consisting of fine concentric growth lines, radial capillae, with microspines arising from some capillae, spine bases appear to extend into the primary shell layer. Its dorsal interior features a pseudoseptum supporting the cardinalia. Micro-ornament of Cyrtospirifer varies widely and is a useful criterion for characterization of species of the genus. Most Frasnian species retained in the genus have micropustulate shells. Two late Givetian and Frasnian phylogenetic species groups of Cyrtospirifer are recognized based on similarities of shell form and external and internal shell features. Species of the verneuilisyringothyriformis group have transverse alate shells, and are the most abundant and widespread group in Frasnian deposits worldwide. The verneuiliformis group includes the oldest known species of Cyrtospirifer with narrow hinges and more inflated ventral valves where shell width is close to or equal to length. The oldest Cyrtospirifer originated in western Europe during the late Givetian, and subsequently migrated at different times during the Frasnian into other shelf areas of Eurasia, North America and China. The initial migration of Cyrtospirifer into tropical and subtropical shelf settings in North America coincided with the middle Frasnian eustatic sea level rise of Devonian Transgressive-Regressive (T-R) cycle IIc of Johnson and others. A second late Frasnian dispersal from western Canada to subtropical carbonate and clastic shelves in the southwestern and central U.S. coincided with the initial sea level rise of T-R cycle IId of Johnson and others. The Frasnian species Cyrtospirifer glaucus Crickmay, 1952a (middle Frasnian of western Canada) is the type species for Regelia Crickmay, 1952b, and is considered a valid genus, and is not a synonym of C. chemungensis (Conrad, 1842) as previously interpreted by some authors. Regelia differs from Cyrtospirifer in the absence of a delthyrial plate, complete in-filling of the delthyrial cavity by secondary shell material, its simpler rod-like teeth, and its fewer medial sinal shell plications. Species of Regelia are restricted to the middle to late Frasnian of North America.

Three European taxa of the Trhypochthonius-tectorum complex are differentiated and described: Trhypochthonius tectorum (Berlese) s. str., T. silvestris europaeus n. subsp. and T. japonicus n. forma occidentalis. These taxa are compared with T. americanus (Ewing), T. silvestris Jacot and T. japonicus Aoki. Because of the high similarity among these species, a biometrical analysis is performed which confirmed three species groups with disjunct distributions: Trhypochthonius tectorum in Europe with T. tectorum americanus (n. comb.) in North America, T. silvestris in North America with T. s. europaeus n. subsp. in Europe, T. japonicus in Japan with T. japonicus n. forma occidentalis in Europe. The relationships of further Palaearctic species of this complex are discussed and we propose taxonomical changes: Trhypochthonius tectorum fujinitaensis Fujikawa (n. comb.) and T. t. stercus Fujikawa (n. comb.); T. silvestris misumaiensis Fujikawa (n. comb.) and T. s. septentrionalis Fujikawa (n. comb.). The disjunct biogeographical distribution of the members of the three species leads to the assumption of a relative high geological age of the parthenogenetic species-complex of “T. tectorum s. lat.”. A key for the Central European species of Trhypochthonius is presented.

Abstract Two extinct species of the modern genus Tetramorium Mayr, T. paraarmatum sp. n. and T. kulickae sp. n., are described from the Baltic amber (Poland, ca. 37 Ma). This is the first record of the fossil species of this genus. Described species resemble recent Palaearctic species, and we preliminarily place them to the inerme and caespitum species groups, respectively. Findings of other, previously non-recorded and not described yet fossil Tetramorium species from the Middle (or possibly Early) Eocene and Miocene deposits of Europe and North America are discussed.

The Australian wolf spider (Lycosidae Sundevall, 1833) genus Tasmanicosa Roewer, 1959 with Lycosa tasmanica Hogg, 1905 as type species is revised to include 14 species: T. godeffroyi (L. Koch, 1865), comb. nov. (= Lycosa tasmanica Hogg, 1905, syn. nov.; = Lycosa zualella Strand, 1907, syn. nov.; = Lycosa woodwardi Simon, 1909, syn. nov.); T. fulgor sp. nov.; T. gilberta (Hogg, 1905) comb. nov.; T. harmsi sp. nov.; T. hughjackmani sp. nov.; T. kochorum sp. nov.; T. leuckartii (Thorell, 1870), comb. nov. (= Lycosa molyneuxi Hogg, 1905, syn. nov.); T. musgravei (McKay, 1974) comb. nov.; T. phyllis (Hogg, 1905) comb. nov. (= Lycosa stirlingae Hogg, 1905, syn. nov.); T. ramosa (L. Koch, 1877), comb. nov.; T. salmo sp. nov.; T. semicincta (L. Koch, 1877) comb. nov.; T. stella sp. nov.; and T. subrufa (Karsch, 1878) comb. nov. Within the Australian wolf spider fauna, the genus Tasmanicosa can be diagnosed by the distinct pattern of radiating light and dark lines forming a “Union-Jack” pattern on the carapace. Male pedipalp morphology identifies the genus as part of the subfamily Lycosinae Sundevall, 1833 due to the presence of a transverse tegular apophysis with dorsal groove guiding the embolus during copulation. However, genital morphology is variable and a synapomorphy based on male pedipalp or female epigyne morphology could not be identified. Members of Tasmanicosa are comparatively large spiders (body length ca. 12–30 mm), that build a shallow burrow, which is sometimes covered with a flimsy trapdoor. Species of Tasmanicosa are largely a Bassian faunal element with preference for open woodlands and/or floodplains, although some species can be found into the semi-arid Australian interior. Two Australian wolf spider species may represent Tasmanicosa based on their original descriptions, but due to immature types in combination with the somatic similarities of all Tasmanicosa species, cannot be identified with certainty. They are therefore considered nomina dubia: Lycosa excusor L. Koch, 1867 and Lycosa infensa L. Koch, 1877. The type species of Orthocosa Roewer, 1960 is transferred to Tasmanicosa; however, in order to prevent some non-Australian wolf spiders in the genus Orthocosa to be transferred into Tasmanicosa, which is considered endemic to Australia, we here place these species into more appropriate genera based on their original descriptions pending a future revision of these species: Arctosa ambigua Denis, 1947 comb. reval.; Alopecosa orophila (Thorell, 1887) comb. nov.; Hygrolycosa tokinagai Saito, 1936 comb. reval. Orthocosa sternomaculata (Mello-Leitão, 1943) is considered a junior synonym of Hogna birabeni (Mello-Leitão, 1943) comb. nov.

Spiders in the genus Cybaeus L. Koch (Araneae : Dictynoidea : Cybaeidae) are common forest-floor inhabitants in western North America and Japan. Here we establish an initial phylogenetic framework for North American Cybaeus. Morphological details for eight proposed species groups are given, and these results, combined with molecular analyses of one nuclear and one mitochondrial gene for six of the eight species groups, suggest that North American Cybaeus species are contained in two broad clades, one Holarctic and one Nearctic (primarily Californian). The Holarctic clade contains the tetricus and angustiarum species groups, which contain mostly widely distributed species. The Californian clade includes the adenes, aspenicolens, consocius, devius, septatus and tardatus species groups, all of which have very restricted ranges. The genus Cybaeus and the Palaearctic species C. tetricus (C.L. Koch) (type species of the genus) and C. angustiarum L. Koch are redescribed and illustrated. A key to species groups is provided. Nine new species endemic to the western Nearctic and included in the molecular analyses are described and illustrated: C. paralypropriapus Bennett, sp. nov. and C. waynei Bennett, sp. nov. (tetricus group); C. sanbruno Bennett, sp. nov. (adenes group); C. thermydrinos Bennett, sp. nov. (aspenicolens group); C. penedentatus Bennett, sp. nov. and C. vulpinus Bennett, sp. nov. (consocius group); C. chauliodous Bennett, sp. nov. and C. somesbar Bennett, sp. nov. (septatus group); and C. gidneyi Bennett, sp. nov. (unplaced).

Draposa gen. nov. is proposed for eight wolf spider species from the Indomalayan Region, all of which were previously placed in the genus Pardosa: Draposa atropalpis (Gravely, 1924) comb. nov., D. lyrivulva (Bosenberg & Strand, 1906) comb. nov. (= Pardosa leucopalpis Gravely, 1924 syn. nov.), D. nicobarica (Thorell, 1891) comb. nov., D. oakleyi (Gravely, 1924) comb. nov., D. porpaensis (U. A. Gajbe, 2004) comb. nov., D. subhadrae (Patel & Reddy, 1993) comb. nov., D. tenasserimensis (Thorell, 1895) comb. nov., and D. zhanjiangensis (Yin, Wang, Peng & Xie, 1995) comb. nov. Species of Draposa share synapomorphies in the copulatory organs, inter alia a complex subpaleal sclerite in the terminal part of the male bulbus. The presence of D. lyrivulva in Japan is put in doubt and the species should be excluded from the list of spiders in that country. Draposa nicobarica (type species) and D. tenasserimensis are redescribed and illustrated for the first time from the type material. Draposa atropalpis is redescribed from material from India and Sri Lanka, D. lyrivulva and D. subhadrae (first record outside India) from material collected in Sri Lanka and D. oakleyi from material from India and Bangladesh.

Holotype Male

Alopecosa atypica Ponomarev, 2008 is known from the holotype male collected in Western Kazakhstan. Here we synonymize it with A. cronebergi (Thorell, 1875), which was described from two syntype females from the Volga River and Daghestan. This species is redescribed in detail and its distribution is shown to be restricted to Russia and Ukraine, and previous records from Hungary are probably mistaken.

Late Glacial And Holocene

The Alps are an important hotspot of species diversity and endemism, as well as a presumed glacial refugium of several species’ groups including land snails. The recent ranges of Alpine endemics are well known, but their fluctuations during the postglacial period mirroring local climate changes are understudied. By analysing five Late Glacial and Holocene mollusc successions from two areas in the southernmost part of the Bohemian Massif (Czech Republic) situated about 100 km north of the Alps, we reveal details of these fluctuations. The Alpine endemic rocky dweller Chilostoma achates had reached the southern part of the Bohemian Massif already in the Late Glacial and disappeared in the Mid-Holocene canopy forest optimum. On the contrary, the northern boundaries of Alpine canopy forest epigeic snails extended further north than today at the turn of the Middle and Late-Holocene, pointing to a more favourable forest microclimate. The earliest known occurrences of several temperate canopy forest central European species, especially Causa holosericea and Discus perspectivus, imply the role of different areas in the Alps as their glacial refugia.
