Araneae) in Florida* by Arthur M
THE FAMILY OONOPIDAE (ARANEAE) IN FLORIDA* BY ARTHUR M. CHICKERING Museum of Comparative Zoology During my study of the family Oonopida.e (Araneae) in Central America and the West Indies I have also become interested in this family as it exists in the State of Florida. In February, March and April, x968, I had an opportunity to collect spiders in Florida as a part of my study of this group of a.nimals with the suppo,rt of the National Science Foundation Grant No. C-B-5o3. In addition to my own collection I have had helpful loans from the. American Museum of Natural History and the University of Florida in Gaines- ville. Dr. W. J. Gertsch has also, made it possible for me to examine the types of Ischnothyreus barrowsi Chamberlin and Ivie, 935 and Stenoonops minutus C. and I., 935, now being placed on semi- permanent loan from the University of Utah to the American Mu- seum of Natural History. Oonopidae from Florida and the West Indies now a pa.rt of the collections in the Museum o Comparative Zoology have also. been very helpful in this study. As usual, my entire collection of this family will be deposited in the Museum of Comparative Zoology. All types described from specimens on loan from the American Museum of Natural History will be deposited in that institution. My appreciation and gratitude are. again expressed for the con- tinued aid and encouragement in the pursuit of my studies extended by the staff of the Museum ot Comparative Zoology. My thanks are also extended to. -

Tarantulas and Social Spiders
Tarantulas and Social Spiders: A Tale of Sex and Silk by Jonathan Bull BSc (Hons) MSc ICL Thesis Presented to the Institute of Biology of The University of Nottingham in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy The University of Nottingham May 2012 DEDICATION To my parents… …because they both said to dedicate it to the other… I dedicate it to both ii ACKNOWLEDGEMENTS First and foremost I would like to thank my supervisor Dr Sara Goodacre for her guidance and support. I am also hugely endebted to Dr Keith Spriggs who became my mentor in the field of RNA and without whom my understanding of the field would have been but a fraction of what it is now. Particular thanks go to Professor John Brookfield, an expert in the field of biological statistics and data retrieval. Likewise with Dr Susan Liddell for her proteomics assistance, a truly remarkable individual on par with Professor Brookfield in being able to simplify even the most complex techniques and analyses. Finally, I would really like to thank Janet Beccaloni for her time and resources at the Natural History Museum, London, permitting me access to the collections therein; ten years on and still a delight. Finally, amongst the greats, Alexander ‘Sasha’ Kondrashov… a true inspiration. I would also like to express my gratitude to those who, although may not have directly contributed, should not be forgotten due to their continued assistance and considerate nature: Dr Chris Wade (five straight hours of help was not uncommon!), Sue Buxton (direct to my bench creepy crawlies), Sheila Keeble (ventures and cleans where others dare not), Alice Young (read/checked my thesis and overcame her arachnophobia!) and all those in the Centre for Biomolecular Sciences. -

EENY-535 A Colonial Tentweb Orbweaver scientific name: Cyrtophora citricola (Arachnida: Araneae: Araneidae)1 G. B. Edwards2 Introduction Distribution Few species of spiders can be considered truly social, but Cyrtophora citricola is widespread in subtropical and more species, particularly web-building spiders, live in tropical areas of Asia, Africa, Australia, and in the warm close proximity to one another, potentially gaining benefits coastal Mediterranean areas of Europe (Blanke 1972, by this association. Among these benefits are sharing of Leborgne et al. 1998). It was found in Colombia in 1996 frame threads (Kullman 1959), improved defense against (Levi 1997, Pulido 2002), the Dominican Republic in 1999 predators and parasites (Cangialosi 1990), improved prey (Alayón 2001), Florida in 2000, and Cuba in 2003 (Alayón capture efficiency (Rypstra 1979, Uetz 1989), and greater 2003). Survey work was performed August 2000, April egg production (Smith 1983). 2001, and July 2002 to document the spread of the species in Florida. The survey was focused on canal bridges because Of the three main types of aggregative behaviors exhibited Cyrtophora citricola has a tendency to make its webs on by spiders, the one with the least social interaction involves the guardrails of canal bridges (Figure 6). The survey work individuals making and maintaining their own webs within in 2000 established a preliminary periphery of infestation a colonial matrix of interconnected webs (Buskirk 1975). in a narrow band from west of Homestead to northeast of One such species, which has become highly successful Homestead. through a lifestyle of colonial aggregation, is the orbweaver Cyrtophora citricola Forskål.

PREDATORY BEHAVIOR OF THE BASILICA SPIDER, MECYNOGEA LEMNISCATA (ARANEAE, ARANEIDAE) BY MARIANNE B. WILLEy1 MARGARET A. JOHNSON2 AND PETER H. ADLER1 1Department of Entomology 114 Long Hall Clemson University Clemson, South Carolina 29634 2Department of Entomology and Nematology University of Florida Gainesville, Florida 32604 ABSTRACT Females of Mecynogea lemniscata (Walckenaer) are generalist predators. Sixteen behavioral acts were described for M. lemnis- cata preying on house flies, carpenter ants, and Asiatic oak wee- vils in the field and laboratory. Behavioral sequences varied with prey type, but generally began with plucking and diverged there- after. The predatory behavior of M. lemniscata is most similar to that of the higher araneids. INTRODUCTION Mecynogea lemniscata is currently placed in the Araneidae in subfamily Cyrtophorinae (Coddington, 1989), despite having many characteristics in common with linyphiids. Mecynogea has a his- tory of taxonomic uncertainty and has been placed in either the Linyphiidae or the Araneidae by various authorities. Within the Araneidae, Mecynogea has been positioned both as a primitive araneid (Kaston, 1964) and as an advanced araneid (Levi, 1980). Manuscript received 30 April 1992 153 154 Psyche [Vol. 99 Some of the past uncertainty surrounding the taxonomic place- ment of Mecynogea is because of the superficial similarity in web structure between Mecynogea and linyphiids; however, web struc- ture is not necessarily a reliable phylogenetic indicator (Levi, 1978). Exline (1948) hypothesized that dome web construction by Mecynogea and Linyphia arose independently through convergent evolution. Similarities between Cyrtophora webs and linyphiid webs also are believed to be the result of convergence (Nentwig and Heimer, 1983; Lubin, 1980), and based on behavior and morphology, Cyrtophora is similar to Araneidae (Blanke, 1972 cited in Lubin, 1980). -

Journal of Hymenoptera Research 60: 111–118. https://doi.org/10.3897/jhr.60.14817 Abstract Polysphinctine wasps of the genus Hymenoepimecis act as koinobiont ectoparasitoids of orb-weaver spi- ders. Hymenoepimecis japi is already known to parasitize the tetragnathid spider Leucauge roseosignata. Here, we record the dome-weaver spider Mecynogea biggiba as a second host for H. japi, as well as the behavioral manipulations induced by the parasitoid. We found that H. japi alters the web construction behavior of M. biggiba, resulting in a complex three-dimensional cocoon web. This modified web differs from that of L. roseosignata, which is a simpler structure composed of a few support threads.
