Book Description
The Micropholcommatidae are a family of tiny, distinctive araneoid spiders, known from southern-temperate habitats throughout Australasia and Chile. The greatest abundance of individuals and the largest diversity of taxa occur in the cool-temperate rainforests of south-eastern Australia and New Zealand, where micropholcommatid spiders can be very common within moss and leaf litter microhabitats. Although poorly studied biologically and largely neglected taxonomically, the Micropholcommatidae are a diverse lineage, with a significantÿ The monograph in this volume presents a complete generic-level revision of the spider family Micropholcommatidae. The phylogenetic position and internal phylogeny of the family are tested with two separate morphological cladistic analyses, the results of which inform a comprehensive generic-level classification. In total, 26 new species, 12 new genera, one new tribe and two new subfamilies are described, taking the total documented micropholcommatid fauna to 58 species. The distribution and Gondwanan biogeography of the family are also discussed, and natural history information is provided where known. Most importantly, the results of this paper present a taxonomic framework and a phylogenetic foundation for all future research on the Micropholcommatidae; a template by which new species can be described and existing species can be identified, and a valuable dataset for exploring phylogenetic hypotheses.

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
Over a period of 10 years, scientists from a coalition of international institutions surveyed the biota of the Gaoligong mountains in western Yunnan, China. Focal taxa included selected plants, vertebrates, and arthropods. The study area lies at the heart of one of the world’s biodiversity hotspots and is home to biomes ranging from subtropical forest to tundra. In this special issue, we report on the results of that survey for micro-orbweaving spiders, cryptic animals mostly less than 1 mm long that build delicate, geometric webs. All told, over 1,000 adult micro-orbweavers were collected and sorted to three dozen species, all new to science. The enormous scale of the world’s biodiversity means that science needs data structures to facilitate organization, aggregation, and instant sharing of data. This publication contributes to major aggregators and indexers of electronic biodiversity data including ZooBank, the Global Biodiversity Information Facility (GBIF), Morphbank, and the Encyclopedia of Life (EOL), supplementing the traditional paper mode. Typical of publications in taxonomy, this paper is composed of several components including the primary biodiversity data (specimen, locality, and related information), media (e.g., photographs and drawings), text elements (e.g., species descriptions), and nomenclature (e.g., new taxonomic names). Once these elements are parsed and absorbed by community databases, they can be disseminated, indexed, and recombined in myriad ways inconceivable for static paper publications. The barely imagined potential of these maturing digital resources makes the early 21st century a very exciting historical moment in taxonomy.

Book Description
This volume merges all geographical and paleogeographical data on all groups of the arachnofauna. The book features topics such as the ecological factors, climate and other barriers that influence the distribution of arachnida. 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.

Book Description
ÿThe Selenopidae are a family of medium to large spiders with extremely flattened bodies. They are exceptional in that both their running and striking speeds place them amongst the world?s fastest animals. They occur in all habitable continents but are most abundant in tropical and adjacent realms. Selenopid spiders are usually found under rocks or under tree bark, and have the ability to squeeze into tight crevices. The family currently comprises around 200 species in five genera. In this monograph, four new genera and 27 new species are described from Australia and the Oriental Region, bringing the world total to nine genera and over 230 species. Several species previously placed in Selenops are transferred to the new genera. The Australian fauna is found to be more diverse than previously documented with a total of 24 species, 23 of which are new. A key to the genera of Selenopidae is provided, as are keys to the species of the new genera Karaops and Makdiops.
