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.

Download or read book Field Guide to South African Spiders written by Ansie Dippenaar-Schoeman and published by Penguin Random House South Africa. This book was released on 2014-02-20 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first-ever field guide to provide information on a vast spectrum of spider species based on their morphology, behaviour and distribution. It’s the first book to introduce all 70 South African spider families including 370 major genera and more than 860 of the more common species. It includes illustrations of all of the families, genera and species as well as more than 2 000 colour photographs and 843 maps. - A thorough summary of morphology, biology and habitat requirements is provided - Species with medical importance are discussed - The morphological characters of all known spider families from South Africa are provided and illustrated with notes on their behavior as well as further reading material - Short morphological data with notes on behaviour and distribution of 370 major genera and 860 species is provided This field guide’s purpose is to enable observers to identify spiders in the field. One of the difficulties facing a spider-watcher is that a large number of spider species are small and extremely well camouflaged and are therefore not easily seen. For some genera you will need a magnifying glass or microscope to be able to identify the specimen to generic or species level. Many species can only be identified by a specialist who has access to a good microscope and the relevant literature. Most of the spiders were photographed alive in their natural settings and only some rare and smaller species were photographed using a camera mounted on a microscope. The illustrations and descriptions make it easy for an inexperienced spider-watcher to identify many of the common species encountered in and around the house. The spiders were divided according to the free-living species and those that build intricate webs to catch their prey. The free-living spiders were further divided according to those found on the vegetation and those living on the ground. Spiders are an abundant, diverse and highly successful group of animals. They are commonly found on farms, in gardens and also in houses. They are important predators in all terrestrial ecosystems and are regarded as the “best friends” of gardeners and farmers in sustainable agriculture because they have the important task of regulating the numbers of potentially harmful insects and mites. However, they are feared and maligned because of the venom they produce. We hope this field guide will help save the lives of a few spiders. It will be valuable for the man on the street, researchers, conservation agencies, students, gardeners, farmers, as well as spider-watchers and photographers.

Download or read book Riceland Spiders of South and Southeast Asia written by A. T. Barrion and published by Int. Rice Res. Inst.. This book was released on 1995 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work, which represents a major contribution to the literature for those interested in spiders or more generally in biological control and crop protection. Spiders are among the most omnipresent and numerous predators in both agricultural and natural ecosystems, and without them insect pest populations would go out of control. Their potential as biological control agents can only be appreciated though a greater understanding of their abundance and species composition in different ecological systems. There is a great need for literature providing guidance on spider identification. This volume provides a comprehensive illustrated guide to the spider fauna of rice in South and Southeast Asia. It is designed to be used by both specialists and novices.The majority of the species covered were collected from a diversity of habitats in the Philippines. The bulk of the book consists of keys to the identification of families, genera, and species of Philippine spiders, illustrated by more than 1,000 line drawings, and 92 color photographs. A total of 341 species belonging to 134 genera within 26 families are recognized. Of these, 257 species and 8 genera are new to science. Also provided are distribution maps for individual species and a classification scheme for Philippine riceland spiders.
