This book was released on 2021 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This study provides a framework for future research on the taxonomy of Neosparassus by testing and confirming its monophyly with molecular data, revisiting and resolving the taxonomic status of several problematic historical species, and by describing the first new species of the genus since 1903. It also provides direction for future systematic research on Neosparassus and other groups of Australian Sparassidae, particularly to test the generic boundaries of Isopeda, Isopedella, and Holconia, and to reconsider the placement of Irileka and Keilira in the Heteropodinae."--from introduction.

This book was released on 2015 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: We review the American spider genus Arachosia O.P.-Cambridge, and present a descriptive taxonomic study with a comparative dichotomous key including 21 species, of which seven are newly described (A. avalosi sp. nov., A. carancho sp. nov., A. kapiipeoi sp. nov., A. magna sp. nov., A. monserrate sp. nov., A. pinhalito sp. nov. and A. tungurahua sp. nov.). Four species names are considered nomina dubia: Oxysoma dubium Berland, Gayenna duplovittata Mello-Leitão, Oxysoma polytrichium Mello-Leitão, and Arachosia sulfurea Mello-Leitão. Arachosia bonneti (Mello-Leitão) is newly synonymized with A. albiventris Mello-Leitão, and A. mezenioides Mello-Leitão with A. freiburgensis Keyserling. Previous problems with the identification of species in a species complex including A. cubana (Banks) are resolved. A disjunct distributional pattern is reported for A. kapiipeoi sp. nov.; a preliminary phylogenetic analysis based on mitochondrial COI sequences shows that these may correspond with two cryptic species. In this contribution, grassland and forests are discussed as the two main habitats inhabited by species of Arachosia. Finally, we propose a hypothesis of matching sexes based on functionality of some genital structures, involving sclerites of the male copulatory organ with structures of the epigyne: the prolateral projection on the primary conductor of the male would have a direct interaction with the lateral projections of the anterior pouch on the median epigynal field of females. Key words: Spider, American, Araneae, Anyphaenidae.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: The genus Meriola Banks currently includes 24 known species of spiders distributed across America, especially in southern South America. They have a nearly straight and narrower posterior eye row compared to other American genera of Trachelidae, and elongated and sharply tipped ventral leg cuspules. The study of specimens of Meriola available in collections revealed two undescribed species, M. avalosi sp. nov. and M. peras sp. nov., and the previously unknown females of M. balcarce Platnick & Ewing and M. quilicura Platnick & Ewing, all of which are described here. The female of M. lineolata (Mello-Leitão) comb. nov., transferred from Cetonana Strand, is described for the first time. Two further new combinations are proposed here: M. macrocephala (Nicolet) comb. nov., transferred from Trachelopachys Simon, and M. setosa (Simon) comb. nov., transferred from Cetonana; these two species are also considered senior synonyms of M. barrosi (Mello-Leitão) and M. hyltonae (Mello-Leitão), respectively. Additionally, a new sex matching of M. ramirezi Platnick & Ewing and M. davidi Grismado is proposed, with a redescription of the female of M. ramirezi provided. New geographical records are provided for all of the species, with images and a revised diagnosis for the genus and the previously known species. Keywords: new spider species, South America, taxonomy, new records, Dionycha"--Page 4.

Download or read book The Stone Huntsman Spider Genus Eusparassus Araneae Sparassidae written by Majid Moradmand and published by . This book was released on 2013 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview on the systematics of the stone huntsman spider genus Eusparassus Simon, 1903 and an identification key to the known species are presented. Six species-groups are proposed: the walckenaeri group (3 species, Eastern Mediterranean to Arabia and parts of North-Eastern Africa), dufouri group (8 species, Iberian Peninsula to parts of North-western Africa), vestigator group (3 species, Central to Eastern Africa and an isolated area in India), jaegeri group (4 species, Southern and South-Eastern Africa), tuckeri group (2 species, South-Western Africa) and doriae group (7 species, Middle East to Central and South Asia). Two species, E. pontii Caporiacco, 1935 and E. xerxes (Pocock, 1901) could not be placed in any of the above groups. The species from Africa and Arabia are revised. The following ten species are re-described: Eusparassus barbarus (Lucas, 1846), E. atlanticus Simon, 1909 stat. nov., E. syrticus Simon, 1909, E. oraniensis (Lucas, 1846), E. letourneuxi (Simon, 1874), E. fritschi (Koch, 1873) stat. rev., E. walckenaeri (Audouin, 1826), E. vestigator (Simon, 1897) comb. nov., E. laevatus (Simon, 1897) comb. nov. and E. tuckeri (Lawrence, 1927) comb. nov. The latter three species are transferred from Olios Walckenaer, 1837. Seven new species are described: Eusparassus arabicus spec. nov. (male, female) from Arabian Peninsula, E. educatus spec. nov. (male, female) from Namibia, E. reverentia spec. nov. (male, female) from Burkina Faso and Nigeria, E. jaegeri spec. nov. (male, female) from South Africa and Botswana, E. jocquei spec. nov. (male, female) from Zimbabwe, E. borakalalo spec. nov. (female) from South Africa and E. schoemanae spec. nov. (male, female) from South Africa and Namibia. Three taxa, E. dufouri maximus Strand, 1906 syn. nov., E. rufobrunneus Caporiacco, 1941 syn. nov. and Olios furcatus Lawrence, 1927 syn. nov. are proposed as junior synonyms of E. oraniensis, E. vestigator comb. nov. and E. tuckeri comb. nov. respectively. Males of E. atlanticus stat. nov. and E. fritschi stat. rev. are described for the first time as in the female of E. vestigator comb. nov. Neotypes are designated for E. barbarus, E. oraniensis and E. letourneuxi (all from Algeria). The male and female of Cercetius perezi Simon, 1902, which was known only from the immature holotype, are described here for the first time. This resulted in recognizing the monotypic and little used generic name Cercetius Simon, 1902 as a synonym of the widely used name Eusparassus. Nearly all the species are illustrated for the first time. Eusparassus concolor Caporiacco, 1939 is transferred to Olios and the replacement name Olios quesitio is proposed because of secondary homonymy. For the majority of the species, new geographical records are presented. The systematics and zoogeography of the currently known species and species groups are discussed. A brief note on the copulation process of E. walckenaeri is presented.

Book excerpt: Learn all about the world of spiders in this complete and comprehensive guide, filled with stunning facts, beautiful photography and diagrams to help you understand everything you ever needed to know about arachnids! Bark spiders spin webs ten times stronger than Kevlar. Jumping spiders are capable of learning, recognizing, and remembering colours. Recluse spiders can tolerate six months of extreme drought and have a toxin-laden bite that can necessitate skin grafts. These are just some of the many amazing facts which you will discover in Spiders of the World, the perfect guide to one of natures most fascinating and varied creatures. This title explores the huge diversity of spider species and their fascinating traits. An introduction outlining the spider’s natural history is followed by 117 illustrated profiles spanning the taxonomic spider families. Beautiful close-up photographs of species from each family are shown, along with population distribution maps, tables of essential information, and commentaries revealing notable characteristics. The family profiles are also organized phylogenetically, and the commentaries in each account reflect different aspects of a spider’s biology.

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.

Download or read book Hot Deserts and Arid Shrublands written by Michael Evenari and published by Elsevier Science & Technology. This book was released on 1985 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work presents an authoritative world-wide view of our knowledge about, and understanding of, hot-desert ecosystems. This includes some semi-arid and arid areas, as well as deserts in the strict sense. The hot deserts are distinguished from the temperate deserts (which form the subject of another volume in the series) by the virtual absence of snowfall, even though frosts may occur. For each major hot-desert region, expert authors have summarized existing knowledge according to a general outline. This includes descriptions of the ecosystem components (climate, soil, flora and fauna), and discussion of interaction between components and overall ecosystem functioning. The information from the regional chapters has then been integrated into a world-wide view in the ''synthesis'' chapters. Because of its length, the volume is published in two parts. The first volume includes the general synthesis chapters, and regional descriptions of the hot deserts of America and Australia, while the second volume covers the hot deserts of Asia and Africa.
