  • Taxonomic Notes on Agroeca (Araneae, Liocranidae)
    Arachnol. Mitt. 37: 27-30 Nürnberg, Juli 2009 Taxonomic notes on Agroeca (Araneae, Liocranidae) Torbjörn Kronestedt Abstract: Agroeca gaunitzi Tullgren, 1952 is stated here to be a junior synonym of A. proxima (O. P.-Cambridge, 1871). The illustrations of the male palp attributed to A. proxima in papers by Tullgren of 1946 and 1952 in fact show A. inopina O. P.-Cambridge, 1886. The record of A. inopina from Finland, quite outside its known distribution range, was based on a misidentification. It is argued that the type species of the genus Agroeca Westring, 1861 should be A. proxima (O. P.-Cambridge, 1871), not A. brunnea (Blackwall, 1833) as currently applied. Protagroeca Lohmander, 1944 is placed as an objective synonym of Agroeca Westring, 1861. Key words: Agroeca gaunitzi, synonyms, type species On the identity of Agroeca gaunitzi Tullgren, 1952 Because Agroeca gaunitzi still appears as a valid Agroeca gaunitzi was described based on a single nominal species (HELSDINGEN 2009, PLATNICK male from the southern part of Swedish Lapland 2009), a re-study of the holotype was undertaken in (TULLGREN 1952).

    A summary list of fossil spiders compiled by Jason A. Dunlop (Berlin), David Penney (Manchester) & Denise Jekel (Berlin) Suggested citation: Dunlop, J. A., Penney, D. & Jekel, D. 2010. A summary list of fossil spiders. In Platnick, N. I. (ed.) The world spider catalog, version 10.5. American Museum of Natural History, online at http://research.amnh.org/entomology/spiders/catalog/index.html Last udated: 10.12.2009 INTRODUCTION Fossil spiders have not been fully cataloged since Bonnet’s Bibliographia Araneorum and are not included in the current Catalog. Since Bonnet’s time there has been considerable progress in our understanding of the spider fossil record and numerous new taxa have been described. As part of a larger project to catalog the diversity of fossil arachnids and their relatives, our aim here is to offer a summary list of the known fossil spiders in their current systematic position; as a first step towards the eventual goal of combining fossil and Recent data within a single arachnological resource. To integrate our data as smoothly as possible with standards used for living spiders, our list follows the names and sequence of families adopted in the Catalog. For this reason some of the family groupings proposed in Wunderlich’s (2004, 2008) monographs of amber and copal spiders are not reflected here, and we encourage the reader to consult these studies for details and alternative opinions. Extinct families have been inserted in the position which we hope best reflects their probable affinities. Genus and species names were compiled from established lists and cross-referenced against the primary literature.

  • Two New Cave-Dwelling Spider Species from the Moroccan High Atlas (Araneae: Liocranidae, Theridiidae)
    Arachnologische Mitteilungen / Arachnology Letters 60: 12-18 Karlsruhe, September 2020 Two new cave-dwelling spider species from the Moroccan High Atlas (Araneae: Liocranidae, Theridiidae) Sylvain Lecigne, Josiane Lips, Soumia Moutaouakil & Pierre Oger doi: 10.30963/aramit6002 Abstract. During a scientific internship in a mountainous area near Agadir, several caves were prospected; the sampled material includ- ed several spider species. Morphological and taxonomical analysis revealed two new species to science: an anophthalmic troglobiont species, Agraecina agadirensis spec. nov. (description based on three females) and a new member of the genus Steatoda in the Mediter- ranean region, Steatoda ifricola spec. nov. (description based on both sexes). Diagnoses, drawings and photos are presented. Keywords: Agadir, comb-footed spiders, Ida Outanane Massif, spiny-legged sac spiders, taxonomy, troglobiont species Zusammenfassung. Zwei neue höhlenbewohnenden Spinnenarten aus dem marokkanischem Hohen Atlas (Araneae: Liocrani- dae, Theridiidae). Während eines wissenschaftlichen Praktikums im Gebirge nah Agadir wurden mehrere Höhlen besucht. Das dort gesammelte Material enthielt mehrere Spinnenarten. Die morphologische und taxonomische Untersuchung erbrachte zwei neue Arten für die Wissenschaft: eine augenlose troglobionte Art, Agraecina agadirensis spec. nov. (drei Weibchen) und eine neue Vertreterin der Gattung in der mediterranen Region, Steatoda ifricola spec. nov. (beide Geschlechter). Diagnosen, Zeichnungen und Fotos werden prä- sentiert.

  • The Structure of Spider Communities in Limestone Quarry Environments
    1998. P. A. Selden (ed.). Proceedings of the 17th European Colloquium of Arachnology, Edinburgh 1997. The structure of spider communities in limestone quarry environments James R. Bell, W. Rod Cullen and C. Philip Wheater Department of Environmental and Geographical Sciences, Manchester Metropolitan University, Manchester, M1 5GD, UK Summary Upland limestone spider communities have not been extensively studied. Spiders of three habitats— a natural daleside, naturally regenerated disused quarries, and quarry faces which have undergone landform replication—have been investigated using pitfall traps as part of a long-term monitoring programme. Catch data of 2055 individuals, representing 77 species from 12 families, is presented for the years 1992 and 1995. No relationship was found between the number of spider species and individuals and the age of the sites. Changes in the species composition were evident between 1992 and 1995. These tended to be greatest for recently disturbed sites and smallest for mature natural daleside habitats. This may be attributed to survival of a population and weather-mediated differ- ences in immigration from surrounding habitats. Additionally, the availablitity of overwintering habitat such as large rocks and moss may explain differences between some sites. Three families were found to be dominant across the sites: Linyphiidae, Lycosidae and Agelenidae, with five species making up 49.5 % of the sample. The autecology of these species is discussed in relation to their distribution. Introduction we present data on the effect of quarrying on spiders and the response of these communities to In Britain, upland spider communities can be severe habitat disturbance. found west of the Tees–Exe line between 300–1300 m where the physical conditions are often harsh due to an extremely variable climate, Study sites steep unstable slopes and thin soils (Ratcliffe, 1977).
