It is based on 190 morphological characters scored for 44 taxa: 37 mynoglenine taxa (ingroup) representing 15 of the 17 known genera and seven outgroup taxa representing the sub- families Stemonyphantinae, Linyphiinae (Linyphiini and Micronetini), and Erigoninae, and a representative of the family Pimoi- dae, the sister-group to Linyphiidae. No fewer than 147 of the morphological characters used in this study are new and defined for this study, and come mainly from male and female genitalia. Parsimony analysis with equal weights resulted in three most parsimonious trees of length 871. The monophyly of the subfamily Mynogleninae and the genera Novafroneta, Parafroneta, Laminafroneta, Afroneta, Promynoglenes, Metamynoglenes, and Haplinis are supported, whereas Pseudafroneta is paraphyletic. The remaining seven mynoglenine genera are either monotypic or represented by only one taxon. Diagnoses are given for all genera included in the analysis. The evolution of morphological traits is discussed and we summarize the diversity and distribu- tion patterns of the 124 known species of mynoglenines. The preferred topology suggests a single origin of mynoglenines in New Zealand with two dispersal events to Africa, and does not support Gondwana origin. © The Willi Hennig Society 2013. Introduction The family represents the second most diverse family of spiders, with 4429 described species (Platnick, 2013) Linyphiidae are the most species-rich spider family in 590 genera, surpassed only by the family Salticidae, within the superfamily Araneoidea, a large clade that with 5570 species in 591 genera. includes one-third of all described spider species The spider family Linyphiidae has been divided into (Blackledge et al., 2009). Linyphiidae have a world- a number of different subfamilies, most of which are wide distribution but are most diverse in colder not monophyletic according to modern phylogenetic regions. At higher latitudes, this family dominates the studies. Currently used subfamilies of Linyphiidae are spider faunas. For instance, 41% of the Danish spider Stemonyphantinae, Mynogleninae, Erigoninae, and fauna (216 of the 523 species) are linyphiids (Scharff Linyphiinae (Micronetini plus Linyphiini; Arnedo and Gudik-Sørensen, 2006) and most species are et al., 2009), of which Mynogleninae with 17 genera widely distributed in northern Europe. At lower lati- and 124 species are one of the smallest and most tudes, the family is well represented but constitutes a recently established. Most species have been described much smaller fraction of the total spider fauna within the past 35 years. The subfamily Mynogleninae (Scharff, 1992, 1993; Sørensen et al., 2002). was established by Lehtinen (1967: 250) for Mynog- lenes insolens Simon, 1905 (now Haplinis rufocephala *Corresponding author.

Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity.

In total, the character matrix includes 47 taxa: 35 linyphiids representing the currently used subfamilies of Linyphiidae (Stemonyphantinae, Mynogleninae, Erigoninae, and Linyphiinae (Micronetini plus Linyphiini)) and 12 outgroup species representing nine araneoid families (Pimoidae, Theridiidae, Nesticidae, Synotaxidae, Cyatholipidae, Mysmenidae, Theridiosomatidae, Tetragnathidae, and Araneidae). The morphological characters include those used in recent studies of linyphiid phylogenetics, covering both genitalic and somatic morphology. Different sequence alignments and analytical methods produce different cladistic hypotheses.

Norw. J. Entomol. 51, 57-66. Surface-active spiders were sampled from a ley and two adjacent field margins on a dairy farm in western Norway, using pitfall traps from April to June 2001. Altogether, 1153 specimens, represent- ing 33 species, were found. In total, 10 species were found in the ley, 16 species in the edge of the ley, 22 species in the field margin “ley/forest” and 16 species in the field margin “ley/stream”. Erigone atra, Bathyphantes gracilis, Savignia frontata and Collinsia inerrans were the most abun- dant species in the ley. C. inerrans was not found in the field margins. This species is previously recorded only a few times in Norway. Diplocephalus latifrons, Tapinocyba insecta, Dicymbium tibiale, Bathyphantes nigrinus and Diplostyla concolor were most abundant in the field margin “ley/ forest”. D. latifrons, D. tibiale and Pardosa amentata were most abundant in the field margin “ley/ stream”, followed by E. atra and B. gracilis. The present results were compared to results from ley and pasture on another farm in the region, recorded in 2000. A Detrended Correspondence Analyses (DCA) of the data sets showed that the spider fauna from the leys were more similar, independent of location, than the fauna in ley and field margins on the same locality. The interactions between cultivated fields and field margins according to spider species composition, dominance pattern and habitat preferences are discussed.

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.

    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.

E-mail: [email protected] 2Department of Biological Sciences, The George Washington University, Washington, D.C. 20052, USA. E-mail: [email protected] Very few studies have addressed the linyphiid fauna of Australia. Most of the existing taxonomic work on Australian linyphiids consists of isolated species descriptions (e.g., Rainbow 1912) or at most are based on small number of species also described outside a revisionary context (e.g., Wunderlich 1976) (but see van Helsdingen 1972 for a revision of the Australian species of the genera Laperousea Dalmas, 1917 and Laetesia Simon, 1908). Microctenonyx subitaneus (O. P.-Cambridge, 1875) is a Holarctic erigonine (Linyphiidae) which has been introduced in many parts of the world, including Australia (Brennan 2004). In this paper we report a new junior synonym of Microctenonyx subitaneus described by Butler (1932) under the name Alaxchelicera ordinaria Butler, 1932. In 1932 L.S.G. Butler, a Melbourne-based arachnologist, published a paper in which he described six new spider genera from Victoria and New South Wales, all of them monotypic. Three of these new genera (Microlinypheus, Plectochetos and Alaxchelicera) he placed in the family Linyphiidae, the remaining three (Platycephala, Eterosonycha and Perissopmeros) were placed in Zodariidae.
