This book was released on 2006 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Australasian ground spiders belonging to the family Prodidomidae are monographed; although only ten species were previously known from the region, the fauna is extraordinarily diverse, encompassing at least seven genera and 138 species. Two generic names are newly synonymized: Hyltonia Birabén with Prodidomus Hentz, and Honunius Simon with Molycria Simon. The type species of the family, Prodidomus rufus Hentz, although originally described from Alabama, is apparently synanthropic and hence widespread; Prodidomus gulosus (Simon) from New Caledonia, Prodidomus imaidzumii Kishida from Japan, and Hyltonia scottae Birabén from Argentina are newly synonymized with P. rufus, and the species is newly recorded from Chile and St. Helena. Seven new species of Prodidomus are described from Western Australia, the Northern Territory, and Queensland. The females of Molycria mammosa (O. P.-Cambridge) and Molycria quadricauda (Simon) are described for the first time, and 34 new species of Molycria are described. The new genus Wydundra is described for 40 new Australian species, and Molycria voc Deeleman-Reinhold, from Malaysia and the Moluccas, is transferred to Wydundra. Molycria splendida Simon is transferred to the new genus Wesmaldra, its male is described for the first time, and 13 new species of Wesmaldra are described from Western Australia and the Northern Territory. Molycria flavipes Simon is transferred to the new genus Nomindra, its male is newly described, Molycria alboplagiata Simon is newly synonymized with that name, and 15 new species of Nomindra are described. The male of Cryptoerithus occultus Rainbow is described for the first time, and 18 new species are assigned to Cryptoerithus. Adult males and females of Myandra cambridgei Simon are described for the first time, as are two new species of Myandra.

Book Synopsis A Revision of the Australasian Ground Spiders of the Families Ammoxenidae, Cithaeronidae, Gallieniellidae, and Trochanteriidae (Araneae, Gnaphosoidea) by : Norman I. Platnick
Download or read book A Revision of the Australasian Ground Spiders of the Families Ammoxenidae, Cithaeronidae, Gallieniellidae, and Trochanteriidae (Araneae, Gnaphosoidea) written by Norman I. Platnick and published by . This book was released on 2002 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Australasian ground spiders belonging to the "lower gnaphosoid" families (i.e., those gnaphosoids that retain a plesiomorphic, complete distal article on the anterior lateral spinnerets) are monographed. The families Ammoxenidae and Cithaeronidae are newly recorded from Australia, and the Australian fauna of the family Gallieniellidae is documented for the first time. Australia is thus the only continent known to house members of all seven currently recognized gnaphosoid families. Ammoxenids, previously known only from southern Africa, are represented in Australia by the new genera Austrammo (described for four new species) and Barrowammo (described for one new species). Cithaeronids are represented by the widespread type species, Cithaeron praedonius O.P.-Cambridge, newly recorded from the Northern Territory. The Australian gallieniellid fauna consists of five genera: Meedo Main, here transferred from the Clubionidae, and four new genera: Neato (described for seven new species), Oreo (described for six new species), and Peeto and Questo (each described for one new species). The male of Meedo houstoni Main is described for the first time, as are 12 new species of that genus. The world trochanteriid fauna consists of 18 genera, of which 15 occur in Australasia; the 18 genera are newly assigned to subfamilies (the relimited Trochanteriinae plus the new subfamilies Trachycosminae and Morebilinae). Within the Trochanteriinae, Corimaethes Simon is newly synonymized with Platyoides O.P.-Cambridge, and its Western Australian type species, C. campestratus Simon, is placed as a junior synonym of the African species P. walteri (Karsch); the species is presumed to have been introduced into Australia prior to 1905 but seems not to have become established. The genus Olin Deeleman-Reinhold, recently described for a species from Sulawesi, is newly recorded from an Australian Indian Ocean territory, Christmas Island. The new genera Tinytrema and Desognaphosa are described for five and 26 new species, respectively. Tinytrema is known only from Australia (including Tasmania); Desognaphosa species occur primarily in northern Queensland, but one extends into New South Wales and one is described from the Solomon Islands. The subfamily Trachycosminae includes the Australian genera Trachycosmus Simon and Trachytrema Simon, both newly transferred from the Gnaphosidae, plus the new genus Trachyspina (described for seven new species). The male of Trachytrema castaneum Simon is newly described, as are one new species of that genus and three of Trachycosmus. The subfamily Morebilinae includes four described and four new genera. Hemicloeina Simon and Pyrnus Simon are transferred to the Morebilinae from the Gnaphosidae, and Fissarena Henschel, Davies, and Dickman is transferred from the Liocranidae. Hemicloea plagusia (Walckenaer), H. fumosa L. Koch, H. cineracea L. Koch, Rebilus diversus (L. Koch), R. praesignus (L. Koch), and R. swarbrecki Dunn and Dunn are transferred to the new genus Morebilus; M. cineraceus and M. praesignis are placed as junior synonyms of M. fumosus and M. diversus, respectively; and nine new species of Morebilus are described. Hemicloea insidiosa Simon is transferred to the new genus Longrita, its male is described for the first time, and eight new species of Longrita are described. Hemicloea plana L. Koch and Rebilus obscurus Berland are transferred to Pyrnus; six new species of Pyrnus are described from Australia, Lord Howe Island, and New Caledonia. Pyrnus flavitarsis (L. Koch) is transferred to the new genus Platorish, its male is described for the first time, and four new species of Platorish are described. Rebilus castaneus Simon and Hemicloea longipes Hogg are transferred to Fissarena, and the male of the former species is described for the first time, as are six new species of Fissarena and 16 new species of Rebilus Simon (which is newly assigned to the Morebilinae). The genus Boolathana is described for two new species from Western Australia. Adults of Hemicloeina somersetensis (Thorell) are described for the first time, and seven new species from Australia and New Guinea are assigned to Hemicloeina. The lamponid generic name Centrina Platnick is preoccupied and is replaced by Centroina. A supplement adds new records for many species, as well as descriptions of the new species Trachyspina daunton and Longrita nathan and of the first known male of Morebilus blackdown, new species.
Book Synopsis A Relimitation and Revision of the Australasian Ground Spider Family Lamponidae (Araneae, Gnaphosoidea) by : Norman I. Platnick
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.
Book Synopsis Field Guide to the Spiders of California and the Pacific Coast States by : Richard J. Adams
Download or read book Field Guide to the Spiders of California and the Pacific Coast States written by Richard J. Adams and published by Univ of California Press. This book was released on 2014-01-28 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.

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.

Book Synopsis Species Concepts and Phylogenetic Theory by : Quentin D. Wheeler
Download or read book Species Concepts and Phylogenetic Theory written by Quentin D. Wheeler and published by Columbia University Press. This book was released on 2000-06-22 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: No question in theoretical biology has been more perennially controversial or perplexing than "What is a species?" Recent advances in phylogenetic theory have called into question traditional views of species and spawned many concepts that are currently competing for general acceptance. Once the subject of esoteric intellectual exercises, the "species problem" has emerged as a critically important aspect of global environmental concerns. Completion of an inventory of biodiversity, success in conservation, predictive knowledge about life on earth, management of material resources, formulation of scientifically credible public policy and law, and more depend upon our adoption of the "right" species concept. Quentin D. Wheeler and Rudolf Meier present a debate among top systematic biology theorists to consider the strengths and weaknesses of five competing concepts. Debaters include (1) Ernst Mayr (Biological Species Concept), (2) Rudolf Meier and Rainer Willmann (Hennigian species concept), (3) Brent Mishler and Edward Theriot (one version of the Phylogenetic Species Concept), (4) Quentin Wheeler and Norman Platnick (a competing version of the Phylogenetic Species Concept), and (5) E. O. Wiley and Richard Mayden (the Evolutionary Species Concept). Each author or pair of authors contributes three essays to the debate: first, a position paper with an opening argument for their respective concept of species; second, a counterpoint view of the weakness of competing concepts; and, finally, a rebuttal of the attacks made by other authors. This unique and lively debate format makes the comparative advantages and disadvantages of competing species concepts clear and accessible in a single book for the first time, bringing to light numerous controversies in phylogenetic theory, taxonomy, and philosophy of science that are important to a wide audience. Species Concepts and Phylogenetic Theory will meet a need among scientists, conservationists, policy-makers, and students of biology for an explicit, critical evaluation of a large and complex literature on species. An important reference for professionals, the book will prove especially useful in classrooms and discussion groups where students may find a concise, lucid entrée to one of the most complex questions facing science and society.
Book Synopsis The Future of Phylogenetic Systematics by : David Williams
Download or read book The Future of Phylogenetic Systematics written by David Williams and published by Cambridge University Press. This book was released on 2016-07-21 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: Willi Hennig (1913–76), founder of phylogenetic systematics, revolutionised our understanding of the relationships among species and their natural classification. An expert on Diptera and fossil insects, Hennig's ideas were applicable to all organisms. He wrote about the science of taxonomy or systematics, refining and promoting discussion of the precise meaning of the term 'relationship', the nature of systematic evidence, and how those matters impinge on a precise understanding of monophyly, paraphyly, and polyphyly. Hennig's contributions are relevant today and are a platform for the future. This book focuses on the intellectual aspects of Hennig's work and gives dimension to the future of the subject in relation to Hennig's foundational contributions to the field of phylogenetic systematics. Suitable for graduate students and academic researchers, this book will also appeal to philosophers and historians interested in the legacy of Willi Hennig.
