Carinostoma elegans new to the Slovakian harvestmen fauna (Opiliones, Dyspnoi, Nemastomatidae)
(2014)
A new genus and species of small harvestman was found for the first time in Slovakia – Carinostoma elegans (Sorensen, 1894). One male and two females were collected in the Mlyňany arboretum of the Slovak Academy of Science (western Slovakia). Descriptions and photographs of both sexes of C. elegans are provided. Additional comments, and a map of distribution of all species of this genus, are provided.
This paper presents new data, characteristic features, standard body measurements and illustrations of the rare European linyphiid spider Glyphesis taoplesius Wunderlich, 1969; which is recorded here for the first time in Slovakia. The species was found with high abundance in pitfall traps exposed in a floodplain forest near a water reservoir in the lowland Podunajská rovina.
Die Radnetzspinne Cyclosa oculata (Walckenaer, 1802) wurde an elf Orten in der Nordwestschweiz nachgewiesen. Alle Fundorte lagen in Buntbrachen mit relativ hohem Anteil abgestorbener Vegetation vom Vorjahr, relativ niedriger Vegetationshöhe und geringem Anteil von Gräsern an der Vegetation. C. oculata baute ihr kleines Radnetz in Bodennähe, tief in der Vegetation. Unter den ecribellaten Radnetzspinnen Mitteleuropas ist C. oculata einzigartig, da sie manchmal ein rudimentäres Netze baut und verwendet, da sie ihre Kokons in das Netz einbaut, und da sie ein dauerhaftes Detritus-Stabiliment baut. Aufgrund unserer Beobachtungen nehmen wir an, dass das Stabiliment C. oculata zur Tarnung dient.
A survey of spiders of the genus Scytodes Latreille, 1804 in Iran resulted in six species occurring in this country: Scytodes fusca Walckenaer, 1837, S. strandi Spassky, 1941, S. thoracica (Latreille, 1802), S. univittata Simon, 1882 and – recorded for the first time – S. arwa Rheims, Brescovit & van Harten, 2006 and S. makeda Rheims, Brescovit & van Harten, 2006. Illustrations of the newly recorded species and a key to all known Iranian species are presented.
Japanese species of the genus Georissus are revised. Seven species, including two new, G. (Neogeorissus) takahashii sp. nov. and G. (Ne.) satoi sp. nov. are recognized. Georissus (Neogeorissus) sakaii Satô, 1972 and G. (Ne.) katsuoi Nakane, 1995 are synonymized with G. (Ne.) japonicus Satô, 1972. Based on the type series and additional specimens, three subgenera and seven species are (re)described with SEM micrographs of the external morphology and figures of male and female genitalia. The terminology of some structures of the head and the pronotum are redefined for convenience of taxonomy. A key to the Japanese species is also given.
Cicurina japonica (Araneae: Dictynidae) - eine nach Mitteleuropa eingeschleppte Kräuselspinnenart
(2005)
Die ersten beiden Nachweise der ursprünglich ostasiatisch verbreiteten Kräuselspinnen-Art Cicurina japonica (Simon, 1886) für Europa werden vorgestellt. Die umfangreichen Funde im Areal des ehemaligen Güterbahnhofes der Deutschen Bundesbahnen (DB) in Basel erlauben ansatzweise eine ökologische Charakterisierung der Art.
The present study unites data from several excursions in typical Mediterranean lowland ecosystems in Albania during the years 2006 to 2009. Spiders from several different habitat types along the coast were analysed in six districts: Saranda, Fieri, Kavaja, Durrësi, Tirana and Lezha. In total 299 adult specimens were collected. They belong to 82 species, 60 genera and 22 families. Six species are new to the Albanian fauna: Aculepeira armida (Audouin, 1826), Zygiella x-notata (Clerck, 1757), Histopona torpida (C. L. Koch, 1837), Malthonica campestris (C. L. Koch, 1834), Pellenes tripunctatus (Walckenaer, 1802) and Pseudeuophrys erratica (Walckenaer, 1826). With respect to zoogeography, the spider fauna is mainly characterized by the presence of many Palaearctic species.
The paper presents new records of the spider Atypus muralis Bertkau, 1890 in the valleys of the rivers Saale and Unstrut in the south of Saxony-Anhalt in Middle Germany. All specimens were males, caught by pitfall traps in xerothermic steppic grasslands on steep slopes. The geographic distribution of Atypus muralis in the eastern parts of Germany and habitat traits are discussed with special reference to regional climate, vegetation type and soil conditions. The phenology of aboveground activity of Atypus muralis males is shown.
In September 2005, one male specimen of the wolf spider genus Alopecosa was discovered and photographed in heathland near Haltern, North Rhine-Westphalia, Germany. It was identified as A. barbipes (Sundevall, 1833), as it showed the species- and sex-specific tibial hair-brush absent in the sibling species A. accentuata. Three years later, two other specimens of A. barbipes were collected in the same area. These findings indicate that the species is more widespread than originally thought. Some details concerning the distribution of A. accentuata and A. barbipes and the problem of synonymy are discussed.
