AUtapomorphies and synapomorphies are listed seqUentially for each taxa involved, details are discUssed and illUstrated in three phylograms. The taxa Pulchaeschna sUbgen. nov. (type species: Austroaeschna unicornis pulchra TILLYARD) and Notoaeschnini trib. nov. (type genUs: Notoaeschna TILLYARD) are formally established. AUstralian „brachytronine aeshnids“ (Panbrachytronoda tax. nov.: Telephlebiidae s. nov. and Dendroaeschna TILLYARD) are characterized in terms of their chorology and ecology. NUmeroUs photographs of live dragonflies and prepared spe- cimens docUment the diversity of morphology and coloration foUnd among these insects.

  • Spatiotemporal Pattern of Phenology Across Geographic Gradients in Insects
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2017 Spatiotemporal pattern of phenology across geographic gradients in insects Khelifa, Rassim Abstract: Phenology – the timing of recurrent biological events – influences nearly all aspects of ecology and evolution. Phenological shifts have been recorded in a wide range of animals and plants worldwide during the past few decades. Although the phenological responses differ between taxa, they may also vary geographically, especially along gradients such as latitude or elevation. Since changes in phenology have been shown to affect ecology, evolution, human health and the economy, understanding pheno- logical shifts has become a priority. Although phenological shifts have been associated with changes in temperature, there is still little comprehension of the phenology-temperature relationship, particularly the mechanisms influencing its strength and the extent to which it varies geographically. Such ques- tions would ideally be addressed by combining controlled laboratory experiments on thermal response with long-term observational datasets and historical temperature records. Here, I used odonates (drag- onflies and damselflies) and Sepsid scavenger flies to unravel how temperature affects development and phenology at different latitudes and elevations. The main purpose of this thesis is to provide essential knowledge on the factors driving the spatiotemporal phenological dynamics by (1) investigating how phenology changed in time and space across latitude and elevation in northcentral Europe during the past three decades, (2) assessing potential temporal changes in thermal sensitivity of phenology and (3) describing the geographic pattern and usefulness of thermal performance curves in predicting natural responses.

A revised, annotated checklist of the Victorian dragonflies (Insecta: Odonata). Proceedings of the Royal Society of Victoria. 122(1): 9-27. ISSN 0035-9211. Seventy-six species of Odonata are known from Victoria (26 Zygoptera; 50 Anisoptera). In the last ten years one new species Austroaeschna ingrid Theischinger, 2008 has been described from the State; Austroepigomphus praeruptus (Selys, 1857) and Pseudagrion microcephalum (Rambur, 1842) have now been recorded; and records of Rhadinosticta banksi (Tillyard, 1913) and Labidiosticta vallisi (Fraser, 1955) are judged to be erroneous. Generic names of Aeshna, and Trapezostigma have been changed. Some changes in higher level names and relationships, based on recent phylogenetic analyses, have been incorporated. Distribution maps for all species, based on museum collections, are provided.

Odonata, Aeshnidae, Anax imperator, body length, body mass, larval rearing, sexual size dimorphism, traits Abstract. Insect larval development affects adult traits but the biometric relationships are usually poorly understood, including large odonates. In this study, measurements of morphological traits of larvae, exuviae and adults of Anax imperator were recorded. They were used to investigate the effects of early development on adult morphology. Results showed an increase in larval length during the fi nal instar and the length of its exuviae signifi cantly exceeded that of the larva. Length and body mass of teneral adults were strongly related to the length of their exuviae. Adult males were signifi cantly longer than adult females, while both had the same body mass at emergence. Length of teneral adults was negatively related to the date of emergence in both sexes. During maturation, body mass of males only increased slightly whereas that of females increased greatly. Mature specimens were also signifi cantly longer than teneral individuals.

  • Aquatic and Terrestrial Vegetation Influence
    AQUATIC AND TERRESTRIAL VEGETATION INFLUENCE LACUSTRINE DRAGONFLY (ORDER ODONATA) ASSEMBLAGES AT MULTIPLE LIFE STAGES By Alysa J. Remsburg A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Zoology) at the UNIVERSITY OF WISCONSIN – MADISON 2007 i ACKNOWLEDGMENTS Reflecting on the contributions of my colleagues and friends during my graduate studies gives me a strong sense of gratitude for the community of support that I have enjoyed. The people who surround and support me deserve more thanks than I can describe here. Friends and family have supported my graduate studies by generously accommodating my tight schedule and warmly offering encouragement throughout the process. Monica Turner guided my graduate studies in numerous ways. It was her trust in my abilities and willingness to learn about a new study organism that first made this research possible. She encouraged me to pursue the research questions that most interested and inspired me, although it meant charting territory that was new to both of us. Monica served as the ideal mentor for me by requiring clear communication, modeling an efficient and balanced work ethic, providing critical reviews, and listening compassionately. This research benefited from the expertise and generosity of outstanding Wisconsin ecologists. Members of my graduate research committee, Steve Carpenter, Claudio Gratton, Tony Ives, Bobbi Peckarsky, and Joy Zedler, all offered useful suggestions and critiques on experimental design, pressing research questions, and the manuscripts. Cecile Ane provided additional statistical advice and smiles. Bill Smith, Bob DuBois, and Robert Bohanan answered (or reassured me that I should try to answer) many questions about field methods, Odonata biology, and species identification.

THEISCHINGER Abstract: Larvae and adults of Austrophlebia TILL YARD are analysed, resulting in the description of a second species. Key words: Austrophlebia, revision, Australia. Introduction During recent studies towards a key to the last instar larvae and exuviae of the Australian dragonflies, the larvae of Austrophlebia TlLLYARD, supposedly a mono- typic genus, were found to be heterogeneous. Differences exist particularly in the shape of the prementum, generally the most use- ful character for identifying closely allied species in many aeshnid genera, most notably in Austroaeschna SELYS, the genus considered closest to Austrophlebia. Whereas marked differences were found between populations from south of latitude 21°S and populations from north of latitude 18°S, no major morphological differences were detected between single populations from inside the two regions. Further study, involving also adults of Austrophlebia, finally revealed that the two morphologically distinct groups of larvae also produce two types of adults. The dif- ferences between the two groups of populations of Austrophlebia in colouration of adults and in adult and larval morphology are of a magnitude which indicates distinctness at species level. A second species of Austrophlebia is, therefore, described below and compared with A.
