This book was released on 1987 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The 'hypochiloids, ' the most primitive known araneomorph spiders, are reclassified on the basis of a cladistic analysis of the results of a comparative morphological survey. Platnick's previous hypothesis--that the family Hypochilidae, containing two genera (Hypochilus, from the United States, and Ectatosticta, from China), represents the sister group of all other araneomorphs--is corroborated, and four new species of Hypochilus (H. pococki, H. coylei, H. sheari, and H. kastoni) are described. However, Platnick's and all other previous arrangements of the remaining 'hypochiloid' genera are rejected in favor of a hypothesis that these austral taxa form a monophyletic group, the superfamily Austrochiloidea, containing two families, the Austrochilidae and Gradungulidae. The family Hickmaniidae Lehtinen, containing only the Tasmanian species Hickmania troglodytes (Higgins and Petterd), is relegated to subfamilial status within the Austrochilidae. In its sister group, the Austrochilinae, Lehtinen's synonymy of Austrochilus manni Gertsch and Zapfe with Thaida peculiaris Karsch is rejected on both the specific and generic levels; four new species of Austrochilus (A. melon, A. schlingeri, A. franckei, and A. newtoni) and one new species of Thaida (T. chepu) are described from Chile and adjacent Argentina. Five new genera of Gradungulidae are described: Spelunga, containing S. cavernicola, new species, from New Zealand; Tarlina, containing five new species (T. noorundi, type species, T. milledgei, T. smithersi, T. daviesae, and T. simipes) and T. woodwardi (Forster), transferred from Gradungula, all from eastern Australia; Kaiya, containing three new species (K. terama, type species, K. bemboka, and K. parnabyi) and K. brindabella (Moran), transferred from Gradungula, all from eastern Australia; Pianoa, containing P. isolata, new species, from New Zealand; and Macrogradungula, containing M. moonya, new species, from Queensland, Australia"--Page 3

Download or read book Australian Assassins Part I A review of the Assassin Spiders Araneae Archaeidae of mid eastern Australia written by Michael G. Rix and published by PenSoft Publishers LTD. This book was released on 2011-08-15 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Assassin Spiders of the family Archaeidae are an ancient and iconic lineage of basal araneomorph spiders, characterised by a specialised araneophagic ecology and unique, ?pelican-like? cephalic morphology. Found throughout the rainforests, wet sclerophyll forests and mesic heathlands of south-western, south-eastern and north-eastern Australia, the genus Austrarchaea Forster & Platnick, 1984 includes a diverse assemblage of relictual, largely short-range endemic species. With recent dedicated field surveys and significant advances in our understanding of archaeid biology and ecology, numerous new species of assassin spiders have been discovered in the montane sub-tropical and warm-temperate closed forests of mid-eastern Australia, including several rare or enigmatic taxa and species of conservation concern. This fauna is revised and 17 new species are described from south-eastern Queensland and eastern New South Wales: A. alani sp. n., A. aleenae sp. n., A. binfordae sp. n., A. christopheri sp. n., A. clyneae sp. n., A. cunninghami sp. n., A. dianneae sp. n., A. harmsi sp. n., A. helenae sp. n., A. judyae sp. n., A. mascordi sp. n., A. mcguiganae sp. n., A. milledgei sp. n., A. monteithi sp. n., A. platnickorum sp. n., A. raveni sp. n. and A. smithae sp. n. Adult specimens of the type species, A. nodosa (Forster, 1956) are redescribed from the Lamington Plateau, south-eastern Queensland, and distinguished from the sympatric species A. dianneae sp. n. A key to species and a molecular phylogenetic analysis of COI and COII mtDNA sequences complement the species-level taxonomy, with maps, habitat photos, natural history information and conservation assessments provided for all species.

It also elaborates on the characteristics of the distribution such as arachnida at high altitude (e.g. Himalaya), in caves, in polar regions and highlights differences between the arachnofauna of e.g. Mediterranean regions vs Central Europe, West African vs Indomalayan and more. Furthermore, amongst other topics the volume also includes chapters on the systems of arachnida, fossil orders, dispersal and dispersion, endemics and relicts, regional arachnogeography, cave and high altitude arachnida.

Download or read book A Revision and Phylogenetic Analysis of the Spider Subfamily Phyxelidinae Araneae Amaurobiidae written by Charles E. Griswold and published by . This book was released on 1990 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The subfamily Phyxelidinae Lehtinen of the Amaurobiidae is diagnosed and revised, and a key to and distribution maps of the 53 valid and 1 undescribed species are provided. The subfamily comprises 12 genera placed in three newly described tribes: Ambohima, new genus, Kulalania new genus, Lamaika, new genus, Malaika Lehtinen, Matundua Lehtinen, Namaquarachne, new genus, Phyxelida Simon, Pongolania, new genus, Themacrys Simon, Vidole Lehtinen, Vytfutia Deeleman-Reinhold, and Xevioso Lehtinen. Vytfutia is newly transferred to the Phyxelidinae. Members of the Phyxelidinae occur in Africa, Madagascar, the eastern Mediterranean, and southeast Asia. The Phyxelidinae is monophyletic and is defined by the following putative synapomorphies: at least some of the basal prolateral setae on the palpal femora of both sexes are enlarged, and in many species the setae are also modified into thorns; the tarsal trichobothria are lost and the metatarsal pattern is reduced to a single subapical dorsal trichobothrium; and the origin of the calamistrum is shifted to the median part of the fourth metatarsus. Previous familial placements of the spiders here placed in the Phyxelidinae are critically evaluated, and it is concluded that the Phyxelidinae are members of the Amaurobiidae. The Amaurobiidae is redefined on the basis of putative synapomorphies as spiders with a divided cribellum which have simple, sclerotized retrolateral and dorsal tibial processes on the male palp (however, the retrolateral process is lost in all Phyxelidinae except Vytfutia). A cladogram for the 54 species of the Phyxelidinae derived through numerical parsimony analysis using Swofford's program PAUP is presented. The following new taxa are proposed: new tribes: Vytfutiini, Vidoleini, and Phyxelidini; new genera: Ambohima (type species Ambohima sublima, new species, from Madagascar), Kulalania (type species Kulalania antiqua, new species, from Kenya), Lamaika (type species Lamaika distincta, new species, from South Africa), Namaquarachne (type species Namaquarachne khoikhoiana, new species, from South Africa), and Pongolania (type species Pongolania pongola, new species, from South Africa); new species: Ambohima sublima and A. pauliani; Kulalania antiqua; Lamaika distincta; Malaika delicatula; Namaquarachne angulata, N. khoikhoiana, N. thaumatula, and N. tropata; Phyxelida abyssinica, P. anatolica, P. apwania, P. carcharata, P. crassibursa, P. eurygyna, P. fanivelona, P. irwini, P. jabalina, P. kipia, P. malagasyana P. pingoana, P. sindanoa, and P. umlima; Pongolania chrysionaria and P. pongola; Themacrys ukhahlamba; Vidole V. helicigyna, V. lyra, and V. sothoana; Xevioso amica, X. aululata, X. colobata, X. jocquei, X. kulufa, X. lichmadina, and X. orthomeles. The following new synonymies are proposed: Haemilla grindleyi Lawrence with Malaika longipes (Purcell); Haemilla profundissima Lawrence with Vidole capensis (Pocock). The synonymies of Auximus schreineri Purcell with Auximus capensis Pocock, and of Haemilla tanganensis Simon and Fage with Amphigyrum nebulosum Tullgren, are rejected. Themacrys stolida Simon is considered a nomen dubium"--Page 3

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 The Evolution of Primary Sexual Characters in Animals written by Janet Leonard and published by Oxford University Press. This book was released on 2010-07-19 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies.Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of "primary" sexual characters. A third approach to the evolution of reproductive interactions after copulation or insemination has been to consider the process one of sexual conflict. That is, the reproductive processes of a species may reflect, as does the mating system, evolution acting on males and on females, but in different directions.In this volume, authors explore a wide variety of primary sexual characters and selective pressures that have shaped them, from natural selection for offspring survival to species-isolating mechanisms, sperm competition, cryptic female choice and sexual arms races. Exploring diverse reproductive adaptations from a theoretical and practical perspective, The Evolution of Primary Sexual Characters will provide an unparalleled overview of sexual diversity in many taxa and an introduction to the issues in sexual selection that are changing our view of sexual processes.

Available in PDF, EPUB and Kindle. Book excerpt: Biogeography and Evolution in New Zealand provides the first in-depth treatment of the biogeography of New Zealand, a region that has been a place of long-enduring interest to ecologists, evolutionary scientists, geographers, geologists, and scientists in related disciplines. It serves as a key addition to the contemporary discussion on regionalization—how is New Zealand different from the rest of the world? With what other areas does it share its geology, history, and biota? Do new molecular phylogenies show that New Zealand may be seen as a biological ‘parallel universe’ within global evolution?

Download or read book Attachment Structures and Adhesive Secretions in Arachnids written by Jonas O. Wolff and published by Springer. This book was released on 2016-12-13 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book surveys attachment structures and adhesive secretions occurring in this class of animals and discusses the relationships between structure, properties, and function in the context of evolutionary trends, and biomimetic potential. Topics comprise mechanical attachment devices, such as clamps, claws, hooks, spines and wraps, as well as hairy and smooth adhesive pads, nano-fibrils, suction cups, and viscid and solidifying adhesives. Attachment is one of the major types of interactions between an organism and its environment. There are numerous studies that deal with this phenomenon in lizards, frogs, insects, barnacles, mussels and echinoderms, but the second largest class of animals, the Arachnida, was highly neglected so far. The authors demonstrated that most arachnid adhesive structures are highly analogous to those of insects and vertebrates, but there are also numerous unique developments with some intriguing working principles. Because arachnid attachment organs have a very strong potential of technological ideas for the development of new materials and systems, inspirations from biology could also be interesting for a broad range of topics in materials and surface engineering.

Available in PDF, EPUB and Kindle. Book excerpt: This book, part of the series Cave and Karst Systems of the World, begins with a review of the interaction between people and caves in Australia (including conservation), followed by descriptions of the spectacular cave diving sites, before comprehensively covering all the major carbonate and noncarbonate karst areas, subdivided by rock type and region, and including the origin of the caves. This is followed by broad overviews of cave minerals and speleothems, cave biology and cave fossils. Each section was written by one or more specialists in the topic and is illustrated by clear diagrams and superb colour photos. The book emphasises the unique aspects of the Australian karst, including the variability in the age of the caves (very old to very young) and the impact of isolation on the stygofauna, as well as the vertebrate fossils preserved in the caves. Written in an easy-to-read style, the book is a primary reference guide to Australian karst and represents a valuable asset for anyone interested in the topic, not only cavers and academics.
