Book excerpt: "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
