Download or read book A Revision of the American Spiders of the Genus Drassyllus Araneae Gnaphosidae written by Norman I. Platnick and published by . This book was released on 1982 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The genus Drasyllus is redefined to include those gnaphosids with a preening comb on metatarsi III and IV, closely spaced posterior median eyes, and a medially situated, bifid terminal apophysis on the male palp, and is hypothesized to be the sister group of Camillina. The 59 known American species, found from southern Canada to Mexico, are placed in eight species groups. Keys, disgnoses, descriptions, illustrations, scanning electron micrographs, locality records, and distribution maps are provided. Zelotes mexicanus (Banks) is transferred to Drasyllus. Drasyllus novus (Banks) and D. dromeus Chamberlin are removed from the synonymy of D. frigidus (Banks) and D. orgilus Chamberlin, respectively, and considered valid. Fourteen specific names are newly synonymized: D. zelotoides (Worley) and D. moronius (Chamberlin), both with D. lamprus (Chamberlin); D. finium Chamberlin and D. dentelifer Chamberlin, both with texamans Chamberlin; D. sporadicus Muma with D. dixinus Chamberlin; D. virginianus Chamberlin with D. novus (Banks); D. ostegae Chamberlin with D. aprilinus (Banks); D. lutzi Chamberlin and D. devexus Chamberlin, both with D. dromeus Chamberlin; D. monicus Chamberlin with D. proclesis Chamberlin; D. lasalus Chamberlin and Gertsch and D. hubbelli Chamberlin and Gertsch, both with D. mexicanus (Banks); and D. mephisto Chamberlin and D. coahuilanus Gertsch and Davis, both with D. lepidus (Banks). The males of D. eremitus Chamberlin, D. nannellus Chamberlin and Gertsch, D. seminolus Chamberlin and Gertsch, D. lamprus (Chamberlin), D. louisianus Chamberlin, D. orgilus Chamberlin, D. arizonensis (Banks), D. saphes Chamberlin, and D. fractus Chamberlin, and the females of D. socius Chamberlin, D. inanus Chamberlin and Gertsch, D. eremophilus Chamberlin and Gertsch, D. ellipes Chamberlin and Gertsch, and D. prosaphes Chamberlin are described for the first time. Twenty-three new species are described from the southern United States and Mexico"--P. [3].

Book Field Guide to the Spiders of California and the Pacific Coast States

Download or read book Field Guide to the Spiders of California and the Pacific Coast States written by Richard J. Adams and published by Univ of California Press. This book was released on 2014-01-28 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.
