Dna Sequence Data Indicates the Polyphyl Y of the Family Ctenidae (Araneae )
1993. The Journal of Arachnology 21 :194–201 DNA SEQUENCE DATA INDICATES THE POLYPHYL Y OF THE FAMILY CTENIDAE (ARANEAE ) Kathrin C . Huber', Thomas S . Haider2, Manfred W . Miiller2, Bernhard A .

Barth' : 'Institut fair Zoologie, Althanstr . 14; 1090 Wien; and 2lnstitut fur Mikrobiologie and Genetik; Dr. Bohrgasse 9 ; 1030 Wien (Vienna), Austria . ABSTRACT. Mitochondrial DNA fragments comprising more than 400 bases of the 16S rDNA from nine spider species have been sequenced: Cupiennius salei, C. getazi, C. coccineus and Phoneutria boliviensis (Ctenidae), Pisaura mirabilis, Dolomedes fimbriatus (Pisauridae), Pardosa agrestis (Lycosidae), Clubiona pallidula (Clubi- onidae) and Ryuthela nishihirai (syn. Heptathela nishihirai; Heptathelidae: Mesothelae). Sequence divergence ranges from 3–4% among Cupiennius species and up to 36% in pairwise comparisons of the more distantly related spider DNAs. Maximally parsimonious gene trees based on these sequences indicate that Phoneutri a and Cupiennius are the most distantly related species of the examined Lycosoidea . The monophyly of the family Ctenidae is therefore doubted ; and a revision of the family, which should include DNA-data, is needed . Cupiennius salei (Ctenidae) is one of the most get a high copy number of the DNA segment of extensively studied species of spiders (see Lach - interest.

Submissions will not be considered unless this form is filled out completely. The proposer is expected to be familiar with the rules, recommendations, and procedures outlined in the “Use and Submission of Common Names” on the ESA website and with the discussion by A.B. Gurney, 1953, Journal of Economic Entomology 46:207-211. 1. Proposed new common name: Four species in the spider genus Cupiennius: 1) redfaced banana spider, 2) spotlegged banana spider, 3) redlegged banana spider, 4) Sale’s banana spider 2. Previously approved common name (if any): none 3. Scientific name (genus, species, author): 1) Cupiennius chiapanensis Medina, 2) Cupiennius getazi Simon, 3) Cupiennius coccineus F. O. Pickard-Cambridge, 4) Cupiennius salei (Keyserling) Order: Araneae Family: Ctenidae Supporting Information 4. Reasons supporting the need for the proposed common name: For the last decade, I have been working on a project involving spiders that have been brought into North America in international cargo. I am in the process of summarizing the work and writing a manuscript. Some of these spiders are huge (leg span 50 to 70 mm) and typically cause strong reaction by cargo processors and produce handlers who discover these creatures when they are unloading and unpacking bananas. One of the spiders, C. chiapanensis, (which has bright red cheliceral hairs – see cover of American Entomologist, 2008, volume 54, issue 2) has caused several misidentifications by qualified arachnologists because 1) this spider was unknown until it was given its scientific name in 2006 and 2) prior to the 21st century, the only reference that many entomologists had to ID international spiders was a children’s book, The Golden Guide to Spiders by Levi and Levi. -
Birth of Maria Sibylla Merian Naturalist and Artist Maria Sibylla Merian Was Born on April 2, 1647, in Frankfurt-Am- Main, Germany
This Day in History… April 2, 1647 Birth of Maria Sibylla Merian Naturalist and artist Maria Sibylla Merian was born on April 2, 1647, in Frankfurt-am- Main, Germany. Merian spent her life studying insects and plants and capturing them in beautifully detailed paintings and drawings. Merian’s father was an engraver and publisher, but he died when she was three. Her mother remarried artist Jacob Marrel in 1651 and he encouraged her to paint and draw. When she was 13, Merian did her first painting of plants and insects based on live specimens she collected. She was fascinated by caterpillars and collected all she could find so she could witness how they changed into beautiful butterflies and moths. Merian married her stepfather’s apprentice, Johann Andreas Graff, in 1665 and they moved to Nuremberg in 1670. She The set of four Merian Botanicals stamps were continued to paint and design embroidery. She also gave drawing issued for Women’s lessons to the daughters of wealthy families. This helped raise her History Month in 1997. social standing while also giving her access to some of the area’s finest gardens, where she could continue to collect and study insects. While other female artists included insects in their paintings of flowers, few others bred or studied them like Merian did. She published her first book on insects in 1679, which focused on their metamorphosis. At the time, little was known about this process. Some This stamp pictures a people wrote about it, but most people believed they were “born of flowering pineapple mud” – having been born spontaneously. -

Koch, 1841) (Theraphosidae, Aviculariinae) is a very rare, colorful and small tarantula found in the Atlantic Rainforest in Bahia and Sergipe. The original description of this species was based on a single female and no illustrations of reproductive organs were presented. After we collected several specimens identified as I. seladonium, we decided to redescribe this species and discovered that the male, previously described as belonging to this species, was misidentified by MELLO LEITÃO (1923). Thus, in this paper the male of I. seladonium is newly described and the reproductive organs of male and female are described and illustrated in detail. Notes on the behavior and natural history of I. seladonium are presented based on the observation of live specimens in the field and in captivity. An immature of I. seladonium was observed constructing a hinged retreat with silk and little pieces of bark, a behavior not previously seen for other Aviculariinae. -

Molecular Basis of the Remarkable Species Selectivity of an Insecticidal
www.nature.com/scientificreports OPEN Molecular basis of the remarkable species selectivity of an insecticidal sodium channel toxin from the Received: 03 February 2016 Accepted: 20 June 2016 African spider Augacephalus Published: 07 July 2016 ezendami Volker Herzig1,*, Maria Ikonomopoulou1,*,†, Jennifer J. Smith1,*, Sławomir Dziemborowicz2, John Gilchrist3, Lucia Kuhn-Nentwig4, Fernanda Oliveira Rezende5, Luciano Andrade Moreira5, Graham M. Nicholson2, Frank Bosmans3 & Glenn F. King1 The inexorable decline in the armament of registered chemical insecticides has stimulated research into environmentally-friendly alternatives. Insecticidal spider-venom peptides are promising candidates for bioinsecticide development but it is challenging to find peptides that are specific for targeted pests. In the present study, we isolated an insecticidal peptide (Ae1a) from venom of the African spider Augacephalus ezendami (family Theraphosidae). Injection of Ae1a into sheep blowflies (Lucilia cuprina) induced rapid but reversible paralysis. In striking contrast, Ae1a was lethal to closely related fruit flies (Drosophila melanogaster) but induced no adverse effects in the recalcitrant lepidopteran pest Helicoverpa armigera. Electrophysiological experiments revealed that Ae1a potently inhibits the voltage-gated sodium channel BgNaV1 from the German cockroach Blattella germanica by shifting the threshold for channel activation to more depolarized potentials. In contrast, Ae1a failed to significantly affect sodium currents in dorsal unpaired median neurons from the American cockroachPeriplaneta americana. We show that Ae1a interacts with the domain II voltage sensor and that sensitivity to the toxin is conferred by natural sequence variations in the S1–S2 loop of domain II. The phyletic specificity of Ae1a provides crucial information for development of sodium channel insecticides that target key insect pests without harming beneficial species. -

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. -

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.
