Revision of the Britcheri and Pugnata Groups of Scotinella (Araneae, Corinnidae, Phrurolithinae) with a Reclassification of Phrurolithine Spiders INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear 011 this reproduction. 1.The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)” . I f it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand corner o f a large sheet and to continue from left to right in equal sections with small overlaps. I f necessary, sectioning is continued again—beginning below the first row and continuing on until complete. 4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into your xerographic copy. These prints are available upon request from the Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases the best available copy lias been filmed. University Microfilm s International 300 N.

Valentine John L. Crites Rodger D. Mitchell Charles A. Triplehorn Adviser Department of Zoology Copyright by Andrew Jay Penniman 1985 ACKNOWLEDGEMENTS In the long course of this research man/ people have provided me stimulation, assistance, and counsel. I can never repay them, but I can try to express my gratitude. First among them must be my advisor, Barry Valentine, who has supported and encouraged me throughout my career at Ohio State. When I was considering studying salticids, Charlie Dondale convinced me to work on Scotinella instead. He induced me to open a can of worms far more fascinating than I expected. He, Norm Platnick, and Herb Levi have lent their advice and encouragement, as well as their specimens, repeatedly during this study. Graduate students in the Departments of Zoology, Entomology, and Botany, particularly Eric Juterbock, Charlie Withrow, Eric Smith, Mike Ivie, Mike Hamerski, Rich Miller, Sam Stribling, Rolf Aalbu, Quentin Wheeler, Larry Watrous, and Vicki Funk, have also helped, encouraged, and occasionally chided me. With them I've enjoyed trading specimens and ideas, and some of both have found their way into this work. Many of the OSU faculty have contributed to my education. Clay Cook and Rodger M itchell, especially, have impressed upon me the need to remain aware of developments beyond my field of arachnology. As a teaching associate I have been priviledged to work under Roger Burnard and Wayne Aspey. They understand I that education is for the learner, and helped me learn to educate others. Dr. Charles Triplehorn has given me free access to the spider collection under his care, including the Barrows collection. The availability of comparative material has been valuable. Susan Mahaney and Libby Marschall assisted me in preparation of the line drawings and Dave Stutes operated the scanning electron microscope. Dave Dennis helped me with the final mounting and reproduction of the figures. To all of those above, and to others not named individually, who have offered advice, encouragement, stimulation, and friendship throughout my time at OSU, 1 offer my gratitude. This work has been supported, in part, by a Graduate Student Alumni Research Award from the Graduate School, The Ohio State University, and a summer research associateship from the Department of Zoology, The Ohio State University. The time I've taken to complete this work has consumed many evenings and weekends, especially in the later stages when I've worked at night so I could study spiders during the day. Meriel and Jared have been patient and loving when I've had little time and money to give them. Finally, 1 thank my parents, John B. and Elnora B. Penniman, and grandparents, L.W. and Mary B. Penniman. Through the love and encouragement they gave me, they subtly steered me toward biology in ways none of us realized. In Mom's garden, during summers at Walloon Lake, watching birds at feeders and nest boxes, and on trips over lakes, mountains, prairies, and deserts I began to ask questions. iii VITA December 19,1948 Born - Evanston, Illinois 1971 B.A., Albion College, Albion Michigan 1971 -1975 Teaching Associate, Department of Zoology, The Ohio State University, Columbus, Ohio I 975 M.S., The Ohio State University, Columbus, Ohio 1977-1980 Teaching Associate, The Ohio State University, Columbus, Ohio 1980-1981 Instructor, Department of Biology, Denison University, Granville, Ohio 1981-1982, 1983 Visiting Lecturer, Department of Biology, Denison University, Granville, Ohio PUBLICATIONS 1978.

  • Arachnids (Excluding Acarina and Pseudoscorpionida) of the Wichita Mountains Wildlife Refuge, Oklahoma
    OCCASIONAL PAPERS THE MUSEUM TEXAS TECH UNIVERSITY NUMBER 67 5 SEPTEMBER 1980 ARACHNIDS (EXCLUDING ACARINA AND PSEUDOSCORPIONIDA) OF THE WICHITA MOUNTAINS WILDLIFE REFUGE, OKLAHOMA JAMES C. COKENDOLPHER AND FRANK D. BRYCE The Wichita Mountains are located in eastern Greer, southern Kiowa, and northwestern Comanche counties in Oklahoma. Since their formation more than 300 million years ago, these rugged mountains have been fragmented and weathered, until today the highest peak (Mount Pinchot) stands only 756 meters above sea level (Tyler, 1977). The mountains are composed predominantly of granite and gabbro. Forests of oak, elm, and walnut border most waterways, while at elevations from 153 to 427 meters prair­ ies are the predominant vegetation type. A more detailed sum­ mary of the climatic and biotic features of the Wichitas has been presented by Blair and Hubbell (1938). A large tract of land in the eastern range of the Wichita Moun­ tains (now northeastern Comanche County) was set aside as the Wichita National Forest by President McKinley during 1901. In 1905, President Theodore Roosevelt created a game preserve on those lands managed by the Forest Service. Since 1935, this pre­ serve has been known as the Wichita Mountains Wildlife Refuge. Numerous papers on Oklahoma spiders have been published (Bailey and Chada, 1968; Bailey et al., 1968; Banks et al, 1932; Branson, 1958, 1959, 1966, 1968; Branson and Drew, 1972; Gro- thaus, 1968; Harrel, 1962, 1965; Horner, 1975; Rogers and Horner, 1977), but only a single, comprehensive work (Banks et al., 1932) exists covering all arachnid orders in the state.

Agric. & Cons . Serv. P.O. Box 1269 Gainesville, Florida 32602 USA ABSTRACT Over a seven-year period, approximately 35,000 spiders representing 26 families, 133 genera, and 234 species were captured in Washington County, Mississippi, by pitfall, sweepnet, vacuum, bag, and hand. Specimens were collected in 10 different habitat types and in four vegetational strata . Old-field habitats yielded the most species (152) and residential lawns the fewest (14) . Considering all habitats sampled, the ground layer produced 111 species, the herbaceous strata 133, the shrub layer 49, and the tree strata 30 species . The sweepnet method of capture obtained 128 species, pitfall 95, hand 61, vacuum 53, and bagging 19 species. The largest number of species were obtained in spring and early summer (maximum of 125 in May), with the fewest in mid-winter (Jan . = 24) . Twenty-one species were considered abundant, 51 common, 67 uncommon, and 95 rare . Additions to the state list of Dorris (1972) number 102 species, for a new state total of 364 species . A comparison with the North American fauna and with other surveys indicates that Washington County is underrepresented both in cursorial forms active on the soil surface and web-spinning forms typical of undisturbed habitats .

  • Epigean Spider Diversity in the Classical Karst
    HACQUETIA 8/1 • 2009, 67–78 DOI: 10.2478/v10028-009-0005-z EpIgean spIdEr dIvErsIty In thE clAssIcAl KArst Matjaž GREGORIČ*1 & Matjaž KUNTNER1 Abstract The classical Karst (Kras in Slovenian) is a limestone karst plateau of south-western Slovenia and north- eastern Italy surrounded by flysch or alluvial areas. We explored surface spider species richness in the Karst by conducting a season-long quantitative inventory of the epigean fauna. By examining three localities, each with three succession-stage sites (grassland, overgrowth, forest) we tested for differences in alpha and beta diversity among different successions based on species incidence data. A total of 90 ethylene glycol pitfall traps (10 traps per each of nine sites) operated between 24. V. 2005 and 20. VII. 2006. We recorded a total of 3681 adult spiders belonging to 136 species, 82 genera and 30 families. Of these 28 species are new records for Slovenia. The observed species richness and total adult spider abundances were highest in the spring and early summer, and among succession stages they were highest in grassland (95 species; 1563 individuals), fol- lowed by overgrowth (81 species; 1047 individuals) and forest (64 species; 1071 individuals). By comparing our results with previous pitfall samplings in the Dinaric karst, we conclude that the sampling effort needed for a meaningful estimation of epigean spider diversity was barely sufficient in our study when all data were combined, but completely inadequate in previous samplings. In our study the total species richness was esti- mated by nonparametric statistics to lie at 181, thus 25 % richer than observed.

  • A Summary List of Fossil Spiders
    A summary list of fossil spiders compiled by Jason A. Dunlop (Berlin), David Penney (Manchester) & Denise Jekel (Berlin) Suggested citation: Dunlop, J. A., Penney, D. & Jekel, D. 2010. A summary list of fossil spiders. In Platnick, N. I. (ed.) The world spider catalog, version 10.5. American Museum of Natural History, online at http://research.amnh.org/entomology/spiders/catalog/index.html Last udated: 10.12.2009 INTRODUCTION Fossil spiders have not been fully cataloged since Bonnet’s Bibliographia Araneorum and are not included in the current Catalog. Since Bonnet’s time there has been considerable progress in our understanding of the spider fossil record and numerous new taxa have been described. As part of a larger project to catalog the diversity of fossil arachnids and their relatives, our aim here is to offer a summary list of the known fossil spiders in their current systematic position; as a first step towards the eventual goal of combining fossil and Recent data within a single arachnological resource. To integrate our data as smoothly as possible with standards used for living spiders, our list follows the names and sequence of families adopted in the Catalog. For this reason some of the family groupings proposed in Wunderlich’s (2004, 2008) monographs of amber and copal spiders are not reflected here, and we encourage the reader to consult these studies for details and alternative opinions. Extinct families have been inserted in the position which we hope best reflects their probable affinities. Genus and species names were compiled from established lists and cross-referenced against the primary literature.

    Behavioral Ecology Symposium ’96: Cushing 165 MYRMECOMORPHY AND MYRMECOPHILY IN SPIDERS: A REVIEW PAULA E. CUSHING The College of Wooster Biology Department 931 College Street Wooster, Ohio 44691 ABSTRACT Myrmecomorphs are arthropods that have evolved a morphological resemblance to ants. Myrmecophiles are arthropods that live in or near ant nests and are considered true symbionts. The literature and natural history information about spider myrme- comorphs and myrmecophiles are reviewed. Myrmecomorphy in spiders is generally considered a type of Batesian mimicry in which spiders are gaining protection from predators through their resemblance to aggressive or unpalatable ants. Selection pressure from spider predators and eggsac parasites may trigger greater integration into ant colonies among myrmecophilic spiders. Key Words: Araneae, symbiont, ant-mimicry, ant-associates RESUMEN Los mirmecomorfos son artrópodos que han evolucionado desarrollando una seme- janza morfológica a las hormigas. Los Myrmecófilos son artrópodos que viven dentro o cerca de nidos de hormigas y se consideran verdaderos simbiontes. Ha sido evaluado la literatura e información de historia natural acerca de las arañas mirmecomorfas y mirmecófilas . El myrmecomorfismo en las arañas es generalmente considerado un tipo de mimetismo Batesiano en el cual las arañas están protegiéndose de sus depre- dadores a través de su semejanza con hormigas agresivas o no apetecibles. La presión de selección de los depredadores de arañas y de parásitos de su saco ovopositor pueden inducir una mayor integración de las arañas mirmecófílas hacia las colonias de hor- migas. Myrmecomorphs and myrmecophiles are arthropods that have evolved some level of association with ants. Myrmecomorphs were originally referred to as myrmecoids by Donisthorpe (1927) and are defined as arthropods that mimic ants morphologically and/or behaviorally.
