Biota Neotrop. 11(1a): http://www.biotaneotropica.org. br/v11n1a/en/abstract?inventory+bn0381101a2011. Abstract: In this study we present a database of spiders described and registered from the Neotropical region between 1757 and 2008. Results are focused on the diversity of the group in the State of São Paulo, compared to other Brazilian states. Data was compiled from over 25,000 records, published in scientific papers dealing with Neotropical fauna. These records enabled the evaluation of the current distribution of the species, the definition of collection gaps and priority biomes, and even future areas of endemism for Brazil. A total of 875 species, distributed in 50 families, have been described from the State of São Paulo. -

Final Project Completion Report
CEPF SMALL GRANT FINAL PROJECT COMPLETION REPORT Organization Legal Name: - Tarantula (Araneae: Theraphosidae) spider diversity, distribution and habitat-use: A study on Protected Area adequacy and Project Title: conservation planning at a landscape level in the Western Ghats of Uttara Kannada district, Karnataka Date of Report: 18 August 2011 Dr. Manju Siliwal Wildlife Information Liaison Development Society Report Author and Contact 9-A, Lal Bahadur Colony, Near Bharathi Colony Information Peelamedu Coimbatore 641004 Tamil Nadu, India CEPF Region: The Western Ghats Region (Sahyadri-Konkan and Malnad-Kodugu Corridors). 2. Strategic Direction: To improve the conservation of globally threatened species of the Western Ghats through systematic conservation planning and action. The present project aimed to improve the conservation status of two globally threatened (Molur et al. 2008b, Siliwal et al., 2008b) ground dwelling theraphosid species, Thrigmopoeus insignis and T. truculentus endemic to the Western Ghats through systematic conservation planning and action. Investment Priority 2.1 Monitor and assess the conservation status of globally threatened species with an emphasis on lesser-known organisms such as reptiles and fish. The present project was focused on an ignored or lesser-known group of spiders called Tarantulas/ Theraphosid spiders and provided valuable information on population status and potential conservation sites in Uttara Kannada district, which will help in future monitoring and assessment of conservation status of the two globally threatened theraphosid species T. insignis and Near Threatened T. truculentus. Investment Priority 2.3. Evaluate the existing protected area network for adequate globally threatened species representation and assess effectiveness of protected area types in biodiversity conservation. -
A Summary List of Fossil Spiders
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. -

(2009),24(1-3): 2 In memoriam JEAN-PIERRE MAELFAIT Kortrijk 01/06/1951 Gent 06/02/2009 Jean-Pierre Maelfait is ons ontvallen op 6 februari van dit jaar. We brengen hulde aan een man die veel gegeven heeft voor de arachnologie in het algemeen en meer specifiek voor onze vereniging. Jean-Pierre is altijd een belangrijke pion geweest in het bestaan van ARABEL. Hij was medestichter van de “Werkgroep ARABEL” in 1976 en op zijn aanraden werd gestart met het publiceren van de “Nieuwsbrief” in 1986, het jaar waarin ook ARABEL een officiële vzw werd. Hij is eindredacteur van de “Nieuwsbrief” geweest van 1990 tot en met 2002. Sinds het ontstaan van onze vereniging is Jean-Pierre achtereenvolgens penningmeester geweest van 1986 tot en met 1989, ondervoorzitter van 1990 tot en met 1995 om uiteindelijk voorzitter te worden van 1996 tot en met 1999. Pas in 2003 gaf hij zijn fakkel als bestuurslid over aan de “jeugd”. Dit afscheid is des te erger omdat Jean- Pierre er na 6 jaar afwezigheid terug een lap ging op geven, door opnieuw bestuurslid te worden in 2009 en aldus verkozen werd als Secretaris. Alle artikels in dit nummer opgenomen worden naar hem opgedragen. Jean-Pierre Maelfait nous a quitté le 6 février de cette année. Nous rendons hommage à un homme qui a beaucoup donné dans sa vie pour l’arachnologie en général et plus particulièrement pour Arabel. Jean-Pierre a toujours été un pion important dans la vie de notre Société. -

School of Environmental Sciences, University of East Anglia, Norwich, NR4 7TJ, United Kingdom. ([email protected]) ABSTRACT. The taxonomic composition, observed and estimated species richness, and patterns of community structure of arboreal spider assemblages in eleven sites surrounding the “Banhado Grande” wet plain in the state of Rio Grande do Sul, Brazil, are presented. These sites represent three different vegetational types: hillside (four sites), riparian (five sites) and flooded forests (two sites). The spiders were captured by beating on foliage and “aerial litter”. A sample was defined as the result of beating on twenty bushes, tree branches or “aerial litter” clusters, which roughly corresponds to one-hour search effort per sample. Fifty five samples (five per site) were obtained, resulting in an observed richness of 212 species present as adult or identifiable juveniles. The total richness for all samples was estimated to be between 250 (Bootstrap) to 354 species (Jackknife 2). -

The biodiversity and species composition of the spider community of Marion Island, a recent survey (Arachnida: Araneae) T.T. KHOZA, S.M. DIPPENAAR and A.S. DIPPENAAR-SCHOEMAN Khoza, T.T., S.M. Dippenaar and A.S. Dippenaar-Schoeman. 2005. The biodiversity and species composition of the spider community of Marion Island, a recent survey (Arach- nida: Araneae). Koedoe 48(2): 103–107. Pretoria. ISSN 0075-6458. Marion Island, the larger of the Prince Edward Islands, lies in the sub-Antarctic bio- geographic region in the southern Indian Ocean. From previous surveys, four spider species are known from Marion. The last survey was undertaken in 1968. During this study a survey was undertaken over a period of four weeks on the island to determine the present spider diversity and to record information about the habitat preferences and general behaviour of the species present. Three collection methods (active search, Tull- gren funnels and pitfall traps) were used, and spiders were sampled from six habitat sites. A total of 430 spiders represented by four families were collected, Myro kergue- lenesis crozetensis Enderlein, 1909 and M. paucispinosus Berland, 1947 (Desidae), Prinerigone vagans (Audouin, 1826) (Linyphiidae), Cheiracanthium furculatum Karsch, 1879 (Miturgidae) and an immature Salticidae. The miturgid and salticid are first records. Neomaso antarticus (Hickman, 1939) (Linyphiidae) was absent from sam- ples, confirming that the species might have been an erroneous record. Key words: Araneae, biodiversity, Desidae, Linyphiidae, Marion Island, Miturgidae, Salticidae, spiders. T.T. Khoza & S.M.
