Download or read book A Relimitation and Revision of the Australasian Ground Spider Family Lamponidae Araneae Gnaphosoidea written by Norman I. Platnick and published by . This book was released on 2000 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ground spider family Lamponidae Simon, previously construed to include only the type genus Lampona Thorell, is relimited to encompass 190 species of Australasian gnaphosoids, most of which have been either undescribed or misplaced in the families Corinnidae and Gnaphosidae. Three subfamilies are recognized: the Lamponinae Simon (including nine genera totalling 81 species), the Centrothelinae, new subfamily (type genus Centrothele L. Koch, including 11 genera, totalling 89 species), and the Pseudolamponinae, new subfamily (type genus Pseudolampona, new genus, including two genera, totalling 20 species). Putative synapomorphies for the family, as relimited, include two newly noted characters: a pair of oval, invaginated abdominal sclerites situated just behind the epigastric furrow, and a highly modified promarginal seta originating near the base of the cheliceral fang. As relimited, the lamponids are exclusively Australasian, and are hypothesized to represent the sister group of the worldwide families Gnaphosidae plus Prodidomidae. The most commonly encountered lamponids are large, synanthropic, and occasionally medically important spiders that have generally been identified as Lampona cylindrata (L. Koch) but actually constitute a group of three closely related species: L. cylindrata, L. murina L. Koch, and L. papua, new species. Of these three species, only L. cylindrata has been found in Western and South Australia and in Tasmania, and that species is also common in Victoria and New South Wales, extends north into south-central Queensland, and has apparently been introduced into the South Island of New Zealand. In contrast, only L. murina has been found in eastern Queensland, and that species also occurs south to Victoria and has apparently been introduced into Lord Howe Island, Norfolk Island, the North Island of New Zealand, and the Kermadec Islands; L. papua is known only from New Guinea. Lampona pseudocylindrata Strand is newly synonymized with L. cylindrata; L. formicaria (Urquhart) is removed from the synonymy of L. cylindrata and placed as a junior synonym of L. murina. Three other specific names are newly synonymized within Lampona: L. subaquila Urquhart with L. ruida L. Koch, and L. obnubila Simon and L. paupercula Simon, both with L. brevipes L. Koch. The female of L. quiqueplagiata Simon and the males of L. flavipes L. Koch, L. macilenta L. Koch, L. pusilla L. Koch, L. ruida L. Koch, L. punctigera Simon, and L. foliifera Simon are described for the first time; 47 new species of Lampona are described. The subgenus Lamponina Strand is elevated to generic level. Lampona scutata Strand and Lampona asperrima Hickman are transferred to Lamponina; the male of the former species and the female of the latter are described for the first time. Four new species of Lamponina are described. Seven new genera of lamponines are described: Lamponoides, Lamponata, Lamponova, Lamponicta, and Lamponusa, each for one new species; Lamponega, for three new species; and Lamponella, for 10 new species that are hypothesized to represent the sister group of all other lamponines. Four genera (Aristerus Simon, Asadipus Simon, Centrothele L. Koch, and Stratius Simon) are transferred from the Corinnidae to the Centrothelinae; Prionosternum Dunn is transferred from the Gnaphosidae to the Centrothelinae. Aristerus is placed as a junior synonym of Asadipus, and 18 new species of Asadipus are described. Stratius is placed as a junior synonym of Centrothele; the males of C. lorata L. Koch and C. mutica (Simon) are described for the first time, and eight new species of Centrothele are described. Asadipus lifoui Berland is transferred to the new genus Centrocalia, its female is newly described, and two new species of Centrocalia are described; the genus appears to be endemic to New Caledonia. Asadipus nitidiceps Simon is transferred to Prionosternum and its male is newly described; males previously associated with its newly designated female lectotype belong to P. scutatum Dunn, the female of which is newly described; one new species of Prionosternum is described. Seven other new centrotheline genera are described: Centrina, for 11 new species; Centsymplia, for 1 new species; Longepi, for 8 new species; Queenvic, for 4 new species; Bigenditia, for 2 new species; Graycassis, for 10 new species; and Notsodipus, for 17 new species. The Pseudolamponinae contains two new genera: Pseudolampona, described for 12 new species, and Paralampona, described for 8 new species. Pseudolamponines are hypothesized to represent the sister group of lamponines plus centrothelines. Hypothesized lamponine synapomorphies include a uniquely even endite shape and tubular pedicel sclerites; putative centrotheline synapomorphies include a highly tuberculate carapace, an anterior abdominal scutum in females, an anteriorly truncated ventral pedicel segment, a weakly sclerotized spot on the anterior surface of the chelicerae, and a longitudinal row of three highly modified cylindrical gland spigots on the posterior median spinnerets. Lamponines and centrothelines are united by a deep and sharply demarcated median groove on the palpal endites.

Download or read book Fossil Spiders written by David Penney and published by Siri Scientific Press. This book was released on 2011 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to insects, fossil spiders have received only scant attention in the literature. Previously, the only works available were numerous scientific papers, many published in foreign languages. Most of these are basic descriptive taxonomic works, with very few considering broader biological concepts. Despite a significant increase in the discovery and description of fossil spiders within the last quarter Century this void remained unfilled. Thus, this short monograph aims to achieve several objectives. Firstly, to provide general and up to date background information on the overall importance and diversity of fossils spiders, including an indication of those groups for which the taxonomy is spurious and in need of reassessment. Secondly, to discuss the techniques available for working with fossil spiders and some of the problems encountered by palaeoarachnologists, including bias and limitations of the spider fossil record. Thirdly, the overall evolutionary history of spiders is summarized in the form of an evolutionary tree, which is subsequently used to address key issues of broad interest, such as origins, diversifications and extinctions, including the effects of mass extinctions and predator-prey co-radiations. Finally, the contribution that fossil data can make to understanding the past and present biogeography of the order is considered. This book should be of interest to both amateur and professional arachnologists and palaeontologists and will also serve as a general palaeontological reference work for neonologists studying extant spiders.

Available in PDF, EPUB and Kindle. Book excerpt: Australians have a love–hate relationship with spiders. Some spiders, such as the Redback and the Sydney Funnelweb, inspire fear. Yet Peacock Spiders, with their colourful fan-spreading courtship dances, have won rapturous appreciation worldwide. A Field Guide to Spiders of Australia uses photographs of living animals to help people identify many of the spiders they encounter. Featuring over 1300 colour photographs, it is the most comprehensive account of Australian spiders ever published. With more than two-thirds of Australian spiders yet to be scientifically described, this book sets the scene for future explorations of our extraordinary Australian fauna. This field guide will be enjoyed by naturalists and anyone with an interest in learning more about Australia's incredible arachnids.

Download or read book Spider Venoms written by P. Gopalakrishnakone and published by Springer. This book was released on 2016-05-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.

Download or read book Dung Beetle Ecology written by Ilkka Hanski and published by Princeton University Press. This book was released on 2014-07-14 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many ecosystems dung beetles play a crucial role--both ecologically and economically--in the decomposition of large herbivore dung. Their activities provide scientists with an excellent opportunity to explore biological community dynamics. This collection of essays offers a concise account of the population and community ecology of dung beetles worldwide, with an emphasis on comparisons between arctic, temperate, and tropical species assemblages. Useful insights arise from relating the vast differences in species' life histories to their population and community-level consequences. The authors also discuss changes in dung beetle faunas due to human-caused habitat alteration and examine the possible effects of introducing dung beetles to cattle-breeding areas that lack efficient native species. "With the expansion of cattle breeding areas, the ecology of dung beetles is a subject of great economic concern as well as one of intense theoretical interest. This excellent book represents an up-to-date ecological study covering important aspects of the dung beetle never before presented."--Gonzalo Halffter, Instituto de Ecologia, Mexico City Originally published in 1991. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
