Book Description
"The monogeneric tribe Orsolobini Cooke is removed from the Dysderidae, elevated to familial status, and redefined to include those dysderoids with a raised tarsal organ. As relimited, the family contains 170 species from Australia, Tasmania, New Zealand, the Auckland and Campbell islands, Chile, Argentina, and the Falkland Islands. Six genera are transferred from the Oonopidae to the Orsolobidae: Tasmanoonops Hickman, Cornifalx Hickman, Ascuta Forster, Duripelta Forster, Pounamuella (nomen novum for Pounamua Forster, preoccupied), and Subantarctia Forster. Eighteen new genera are described: Falklandia (type species Orsolobus rumbolli Schiapelli and Gerschman from the Falkland Islands), Mallecolobus (type species M. malacus, new species, from Chile; also including three other new species from Chile), Chileolobus (type species C. eden, new species, from Chile), Osornolobus (type species O. canan, new species, from Chile; also including 16 new species from Chile), Hickmanolobus (type species Oonopinus mollipes Hickman from Tasmania, transferred from the Oonopidae), Australobus (type species A. torbay, new species, from Western Australia), Waipoua (type species W. toronui, new species, from New Zealand; also including Pounamua totara Forster from New Zealand, P. gressitti Forster from Campbell Island, and five other new species from New Zealand), Wiltonia (type species W. graminicola, new species, from New Zealand; also including eight other new species from New Zealand), Tautukua (type species T. isolata, new species, from New Zealand), Bealeyia (type species B. unicolor, new species, from New Zealand), Dugdalea (type species D. oculata, new species, from New Zealand), Anopsolobus (type species A. subterraneus, new species, from New Zealand), Turretia (type species T. dugdalei, new species, from New Zealand), Orongia (type species O. medialis, new species, from New Zealand; also including two other new species from New Zealand), Paralobus (type species Ascuta salmoni Forster from New Zealand), Tangata (type species T. nigra, new species, from New Zealand; also including Ascuta stewartensis Forster, A. rakiura Forster, A. orepukiensis Forster, A. alpina Forster, A. plena Forster, and 11 other new species from New Zealand), Maoriata (type species Ascuta magna Forster from New Zealand; also including two new species from New Zealand), and Waiporia (type species W. wiltoni, new species, from New Zealand; also including Ascuta extensa Forster, A. modica Forster, A. algida Forster, A. mensa Forster, Pounamua hornabrooki Forster, and six other new species from New Zealand). Sixty-two other new species are described in previously established genera: seven Orsolobus from Chile and Argentina, 25 Tasmanoonops from Australia and Tasmania, and 10 Ascuta, 13 Duripelta, 3 Pounamuella, and 4 Subantarctia from New Zealand. Ascuta pallida Forster is transferred to Duripelta. The females of Tangata rakiura (Forster), T. plena (Forster), Waiporia modica (Forster), and Pounamuella ramsayi (Forster) and the male of P. australis (Forster) are described for the first time. The characters of the four dysderoid families are reviewed"--Page 3

Book Description
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.
