  • 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.

In Bangladesh, very few contributions are available on the taxonomic study on these arachnids. The present paper contains an updated checklist of the spider fauna of Bangladesh based on the published records of different workers and the identified collections of the recent studies by the author. It includes a total of 334 species of spiders belong to the infraorders Mygalomorphae and Araneomorphae under 21 families and 100 genera. A brief diagnosis of different families and their domination together with the distribution throughout the country are provided herewith. Key words: Checklist, spiders, Araneae, Arachnida, Bangladesh INTRODUCTION Bangladesh is basically a riverine agricultural country. It lies between 20.35ºN and 26.75ºN latitude and 88.03ºE and 92.75ºE longitude, covering an area of 1,47,570 sq. km (55,126 sq. miles). The country as such offers varied climatic situations viz., temperature, rainfall, humidity, fogmist, dew and Haor- frost, winds etc. (Rashid 1977). With the vast agricultural lands, also there are different kinds of evergreen, deciduous and mangrove forests staying different areas of the country viz., the southern Sunderbans, northern Bhawal and Madhupur forests and eastern Chittagong and Chittagong Hill-Tracts forest. Along with the agricultural lands, each of the forest ecosystems is composed of numerous species of spider fauna of the country.

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.
