Biodiversity Data Journal 9: e69924. https://doi.org/10.3897/BDJ.9.e69924 Abstract Background Long-term monitoring of invertebrate communities is needed to understand the impact of key biodiversity erosion drivers (e.g. habitat fragmentation and degradation, invasive species, pollution, climatic changes) on the biodiversity of these high diverse organisms. The data we present are part of the long-term project SLAM (Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores) that started in 2012, aiming to understand the impact of biodiversity erosion drivers on Azorean native forests (Azores, Macaronesia, Portugal). In this contribution, the design of the project, its objectives and the first available data for the spider fauna of two Islands (Pico and Terceira) are described.

C h a m b e r l i n a n d W i l t o n I v i e The frequency with which members of the Agelenid genus Cybaeus appeared in collections made by the authors in the mountainous and timbered sections of the Pacific coast region and the representations therein of various apparently undescribed species led to the preparation of this review of the known North American forms. One species hereto­ fore placed in Cybaeus is made the type of a new genus Cybaeina. Most of our species occur in the western states; and it is probable that fur­ ther collecting in this region will bring to light a considerable number of additional forms. The drawings accompanying the paper were made from specimens direct excepting in a few cases where material was not available. In these cases the drawings were copied from the figures published by the authors of the species concerned, as indicated hereafter in each such case, but these drawings were somewhat revised to conform with the general scheme of the other figures in order to facilitate comparison.

Biodiversity Data Journal 1: e980. doi: 10.3897/ BDJ.1.e980 Abstract Given the limited success of past and current conservation efforts, an alternative approach is to preserve tissues and genomes of targeted organisms in cryobanks to make them accessible for future generations. Our pilot preservation project aimed to obtain, expertly identify, and permanently preserve a quarter of the known spider species diversity shared between Slovenia and Switzerland, estimated at 275 species. We here report on the faunistic part of this project, which resulted in 324 species (227 in Slovenia, 143 in Switzerland) for which identification was reasonably established. This material is now preserved in cryobanks, is being processed for DNA barcoding, and is available for genomic studies.

E-mail: [email protected] Abstract A new species, Amaurobius caucasicus sp. n., is described based on the holotype male and two male paratypes from Eastern Georgia. A similar species, A. hercegovinensis Kulczyński, 1915, known only from the original description is redescribed. The taxonomic status of Amaurobius species considered as nomina dubia and species described outside the Holarctic are also assessed. Amaurobius koponeni Marusik, Ballarin & Omelko, 2012, syn. n. described from northern India is a junior synonym of A. jugorum L. Koch, 1868 and Amaurobius yanoianus Nakatsudi, 1943, syn. n. described from Micronesia is synonymised with the titanoecid species Pandava laminata (Thorell, 1878) a species known from Eastern Africa to Polynesia. Considerable size variation in A. antipovae Marusik et Kovblyuk, 2004 is briefly discussed.

E-mail: [email protected], [email protected] 3Corresponding author Abstract The genus Emmenomma is revised and now includes three species from Southern Chile, Argentina and Falkland Islands (Islas Malvinas). The type species Emmenomma oculatum is redescribed and considered a senior synonym of E. beauchenicum. Emmenomma oculatum obscurum is removed from synonymy with E. oculatum, raised to the species level and redescribed; the male of this species remains unknown. A new species, Emmenomma joshuabelli sp. nov. is described. The presence of a grate shaped tapetum outside the Lycosoidea clade is described. Detailed images are provided for all known species. Key words: Chile, Spiders, Naevius, Anisacate, Tibial gland Introduction The spider genus Emmenomma was proposed by Simon (1884) based on several male and female specimens from Tierra del Fuego, Chile. Due to its atypical eye pattern, with greatly enlarged lateral eyes, and peculiar male palp, with an elbowed and flexibly attached dorsal tibial apophysis (DTA) that rests on the retrolateral side of the palp and can be easily mistaken for a RTA, Emmenomma is not easily confused with other spiders and there are no synonyms of the generic name.

  • A Cladistic Analysis of Zoropsidae (Araneae), with the Description of a New Genus
    Belg. J. Zool., 132 (2): 141-154 July 2002 A cladistic analysis of Zoropsidae (Araneae), with the description of a new genus Jan Bosselaers “Dochterland”, R. novarumlaan 2, B-2340 Beerse, Belgium ABSTRACT. A cladistic analysis of the spider family Zoropsidae has been performed. The ingroup of the analysis consisted of eight species traditionally classified in Zoropsidae, including Zoropsis cyprogenia Bosselaers, 1997, of which the hitherto unknown male has been recently discovered, and Takeoa nishimurai (Yaginuma, 1963). The outgroup contained four species, belonging to the genera Ctenus Walckenaer, 1805, Acanthoctenus Keyserling, 1876 and Griswoldia Dippenaar-Schoeman & Jocqué, 1997. Three different weighting schemes allowed selection of one preferred, most parsimonious tree. This tree implies that Zoropsis cyprogenia has to be placed in a new genus within Zoropsidae. A description of Akamasia n. gen. is given, as well as a redescription of Acanthoctenus gaujoni Simon, 1906. KEY WORDS: Araneae, Zoropsidae, Ctenidae, Zoropsis, Takeoa, Akamasia, Acanthoctenus, cladistics, parsi- mony, weighting. INTRODUCTION 1876, Centroctenus Mello-Leitão, 1929, Enoploctenus Simon, 1896, Gephyroctenus Mello-Leitão, 1936, According to SIMON (1892: 227-230), the spider family Leptoctenus Koch, 1878, Nothroctenus Badcock, 1932, Zoropsidae Bertkau, 1882, consisted of two subfamilies: Phymatoctenus Simon, 1896, Trujillina Bryant, 1948, and Acanthocteninae, with only one genus, Acanthoctenus Viracucha Lehtinen, 1967. Keyserling, 1876, and Zoropsinae, composed of three Several authors (WUNDERLICH, 1986; LEVY, 1990; genera: Raecius Simon, 1892, Zorocrates Simon, 1888, CODDINGTON & LEVI, 1991; GRISWOLD, 1993; GRISWOLD and Zoropsis Simon, 1878. SIMON (1903: 974-975) later et al., 1999) have since revalidated the family Zoropsidae, added Uduba Simon, 1880 to Zoropsinae.

  • Araneae) in the Tirana District, Albania Blerina Vrenozi & Peter Jäger
    Arachnologische Mitteilungen 44: 81-87 Nürnberg, Dezember 2012 A faunistic study on ground-dwelling spiders (Araneae) in the Tirana district, Albania Blerina Vrenozi & Peter Jäger doi: 10.5431/aramit4412 Abstract: Spiders from the Tirana district of Albania were investigated. Currently, 78 species from 24 families and a colle- ction of 400 specimens from January to August 2010 were recorded for Tirana. A total of 32 new records for the Albanian fauna are included in the present paper. Agraecina lineata (Simon, 1878) is the first record for the Balkan Peninsula.Saitis graecus Kulczyński, 1905 was known before only from Greece and Bulgaria. Presently, 373 spider species are known for Albania. Keywords: Mediterranean, new records Until now, 341 spider spe- cies were known for Albania based on various investiga- tions (most recently delt­ sHeV et al. 2011, Vrenozi 2012).
