Book Description
The genera Agyneta Hull 1911 and Tennesseellum Petrunkevitch 1925 are revised for North America north of Mexico. The synonymy of Meioneta Hull 1920 with Agyneta Hull 1911 proposed by Saaristo 1973 is corroborated. The North American fauna north of Mexico of Agyneta now includes a total of 69 species, of which 31 are new species: A. watertoni n. sp., A. perspicua n. sp., A. aquila n. sp., A. yukona n. sp., A. darrelli n. sp., A. bucklei n. sp., A. erinacea n. sp., A. crawfordi n. sp., A. vinki n. sp., A. panthera n. sp., A. miniata n. sp., A. danielbelangeri n. sp., A. pistrix n. sp., A. flax n. sp., A. barfoot n. sp., A. sandia n. sp., A. spicula n. sp., A. grandcanyon n. sp., A. chiricahua n. sp., A. crista n. sp., A. tuberculata n. sp., A. catalina n. sp., A. ledfordi n. sp., A. platnicki n. sp., A. bronx n. sp., A. paquini n. sp., A. girardi n. sp., A. flibuscrocus n. sp., A. delphina n. sp., A. okefenokee n. sp. and A. issaqueena n. sp. The genus Tennesseellum includes two species, with one new species, T. gollum n. sp. Ten new synonyms are recognized: Meioneta grayi Barnes 1953 = Anibontes mimus Chamberlin 1924; Meioneta dactylata Chamberlin & Ivie 1944, Meioneta officiosa (Barrows 1940) = Meioneta micaria (Emerton 1882); Meioneta imitata Chamberlin & Ivie 1944 = Meioneta leucophora Chamberlin & Ivie 1944; Meioneta ferosa (Chamberlin & Ivie 1943) = Meioneta fillmorana (Chamberlin 1919); Meioneta fuscipes Chamberlin & Ivie 1944 = Meioneta floridana (Banks 1896); Meioneta alaskensis Holm 1960 = Meioneta maritima (Emerton 1919); Meioneta meridionalis (Crosby & Bishop 1936), Meioneta zebrina Chamberlin & Ivie, 1944 = Meioneta parva (Banks 1896); Meioneta zygia (Keyserling 1886) = Meioneta fabra (Keyserling 1886). Ten informal species groups are proposed based on the study on the male palpal conformation of the embolus and radical division; these groups are not intened to be phylogenetic hypotheses. The limits and composition of the subfamily Micronetinae sensu Saaristo & Tanasevitch 1996 are discussed.

Book Description
Spiders are among the most diverse groups of terrestrial invertebrates, yet they are among the least studied and understood. This first comprehensive guide to all 68 spider families in North America beautifully illustrates 469 of the most commonly encountered species. Group keys enable identification by web type and other observable details, and species descriptions include identification tips, typical habitat, geographic distribution, and behavioral notes. A concise illustrated introduction to spider biology and anatomy explains spider relationships. This book is a critical resource for curious naturalists who want to understand this ubiquitous and ecologically critical component of our biosphere.

Book Description
The Californian Floristic Province, located on the Pacific Coast of North America, is a region recognized as a ?biodiversity hotspot?.ÿ The area?s rich floristic diversity is also reflected in its remarkable diversity of mygalomorph spiders ? the group that includes trapdoor spiders, tarantulas, funnel spiders, and their other close relatives.ÿ This monograph documents the species diversity currently attributed to the euctenizid genus Aptostichus Simon distributed primarily throughout California, but also found in the habitats of Arizona and Nevada.ÿ Based on the examination of approximately 2000 specimens from museum and field collections, 40 species are assessed, 33 of which are new to science ?

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.
