E-mail: [email protected] Abstract The Old World Jerusalem cricket (JC) subfamily Siinae contains one genus, Sia, with two subgenera: Sia (Sia) with two fully winged species from southeast Asia, and Sia (Maxentius) with four wingless species from southern Africa. Because there is a dearth of published data about the behavior and biology of these insects, we present new field and laboratory research on southern African Sia (Maxentius), gather museum and literature information, and present guidelines for collecting and rearing specimens. While we make no taxonomic decisions, this review should be useful for future studies, including a needed taxonomic revision. We also compare results from these southern African JCs with recent investigations on related New World taxa, where fascinating biological traits and extensive cryptic biodiversity have been uncovered. DNA analysis reveals that these Old and New World JCs are polyphyletic. Key words: Stenopelmatoidea, Siinae, South Africa, Maxentius Introduction As presently understood, the orthopteran superfamily Stenopelmatoidea (=Gryllacridoidea) consists of six families (Eades et al.

  • Phylogeny of Ensifera (Hexapoda: Orthoptera) Using Three Ribosomal Loci, with Implications for the Evolution of Acoustic Communication

Shaw b a Department of Organismic and Evolutionary Biology, Harvard University, USA b Department of Biology, University of Maryland, College Park, MD, USA Received 9 May 2005; revised 27 September 2005; accepted 4 October 2005 Available online 16 November 2005 Abstract Representatives of the Orthopteran suborder Ensifera (crickets, katydids, and related insects) are well known for acoustic signals pro- duced in the contexts of courtship and mate recognition. We present a phylogenetic estimate of Ensifera for a sample of 51 taxonomically diverse exemplars, using sequences from 18S, 28S, and 16S rRNA. The results support a monophyletic Ensifera, monophyly of most ensiferan families, and the superfamily Gryllacridoidea which would include Stenopelmatidae, Anostostomatidae, Gryllacrididae, and Lezina. Schizodactylidae was recovered as the sister lineage to Grylloidea, and both Rhaphidophoridae and Tettigoniidae were found to be more closely related to Grylloidea than has been suggested by prior studies. The ambidextrously stridulating haglid Cyphoderris was found to be basal (or sister) to a clade that contains both Grylloidea and Tettigoniidae. Tree comparison tests with the concatenated molecular data found our phylogeny to be significantly better at explaining our data than three recent phylogenetic hypotheses based on morphological characters. A high degree of conflict exists between the molecular and morphological data, possibly indicating that much homoplasy is present in Ensifera, particularly in acoustic structures. In contrast to prior evolutionary hypotheses based on most parsi- monious ancestral state reconstructions, we propose that tegminal stridulation and tibial tympana are ancestral to Ensifera and were lost multiple times, especially within the Gryllidae.

  • The Early Evolution of Biting–Chewing Performance in Hexapoda
    Chapter 6 The Early Evolution of Biting–Chewing Performance in Hexapoda Alexander Blanke Abstract Insects show a plethora of different mandible shapes. It was advocated that these mandible shapes are mainly a function of different feeding habits. This hypothesis was tested on a larger sampling of non-holometabolan biting–chewing insects with additional tests to understand the interplay of mandible function, feeding guild, and phylogeny. The results show that at the studied systematic level, variation in mandible biting–chewing effectivity is regulated to a large extent by phylogenetic history and the configuration of the mandible joints rather than the food preference of a given taxon. Additionally, lineages with multiple mandibular joints such as primary wingless hexapods show a wider functional space occupation of mandibular effectivity than dicondylic insects (¼ silverfish + winged insects) at significantly different evolutionary rates. The evolution and occupation of a compa- rably narrow functional performance space of dicondylic insects is surprising given the low effectivity values of this food uptake solution. Possible reasons for this relative evolutionary “stasis” are discussed. 6.1 Introduction Insecta sensu lato (¼ Hexapoda) display a high diversity of mouthpart shapes within the early evolved lineages which started to radiate approximately 479 million years ago (Misof et al. 2014). These shape changes were described qualitatively and were often stated to relate mainly to the type of food consumed (Yuasa 1920; Isely 1944; Evans and Forsythe 1985; Chapman and de Boer 1995). To the knowledge of the author, this and related statements regarding mouthpart mechanics being shaped by functional demands have never been tested in a quantitative framework.

  • A Guide to Arthropods Bandelier National Monument
    A Guide to Arthropods Bandelier National Monument Top left: Melanoplus akinus Top right: Vanessa cardui Bottom left: Elodes sp. Bottom right: Wolf Spider (Family Lycosidae) by David Lightfoot Compiled by Theresa Murphy Nov 2012 In collaboration with Collin Haffey, Craig Allen, David Lightfoot, Sandra Brantley and Kay Beeley WHAT ARE ARTHROPODS? And why are they important? What’s the difference between Arthropods and Insects? Most of this guide is comprised of insects. These are animals that have three body segments- head, thorax, and abdomen, three pairs of legs, and usually have wings, although there are several wingless forms of insects. Insects are of the Class Insecta and they make up the largest class of the phylum called Arthropoda (arthropods). However, the phylum Arthopoda includes other groups as well including Crustacea (crabs, lobsters, shrimps, barnacles, etc.), Myriapoda (millipedes, centipedes, etc.) and Arachnida (scorpions, king crabs, spiders, mites, ticks, etc.). Arthropods including insects and all other animals in this phylum are characterized as animals with a tough outer exoskeleton or body-shell and flexible jointed limbs that allow the animal to move. Although this guide is comprised mostly of insects, some members of the Myriapoda and Arachnida can also be found here. Remember they are all arthropods but only some of them are true ‘insects’. Entomologist - A scientist who focuses on the study of insects! What’s bugging entomologists? Although we tend to call all insects ‘bugs’ according to entomology a ‘true bug’ must be of the Order Hemiptera. So what exactly makes an insect a bug? Insects in the order Hemiptera have sucking, beak-like mouthparts, which are tucked under their “chin” when Metallic Green Bee (Agapostemon sp.) not in use.

  • Molecular Evoloutionary Genetic Studies of Orthopteroid Insects
    MOLECULAR EVOLUTIONARY GENETIC STUDIES OF ORTHOPTEROID INSECTS: A BIBLIOGRAPHY. Since my last review of this topic (Chapco 1997), there has been a virtual explosion in the number of population genetics studies and phylogenetic analyses of grasshoppers, katydids and their kin in which molecular markers (e.g. RAPDs, AFLPs, microsatellites, partial mitochondrial and nuclear sequences and, more recently, complete genomic sequences) have been used as traits. To perform an up-to-date review at this time would be a somewhat daunting task. Instead, I am providing a list of references that have appeared since 1997 and which may prove useful to other researchers. The style I’ve chosen more or less follows that set out by the Journal of Orthoptera Research. Some references, strictly speaking, are not molecular in scope but ones in which comparisons with molecular phylogenetic findings are made (e.g. Cigliano and Amédégnato 2010). Others deal with molecular aspects of development (e.g. Dearden and Akam 2000), which, it is expected, will have phylogenetic implications in the future.

  • Macroinvertebrate Community Responses to Mammal Control
    MACROINVERTEBRATE COMMUNITY RESPONSES TO MAMMAL CONTROL – EVIDENCE FOR TOP-DOWN TROPHIC EFFECTS BY OLIVIA EDITH VERGARA PARRA A thesis submitted to the Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy in Conservation Biology Victoria University of Wellington 2018 Para mi sobrina Violeta Orellana Vergara y su sonrisa hermosa. Tu llegada remeció mi corazón de amor de una manera inimaginable. ¡Sueña en grande! ii Nothing in nature stands alone... (John Hunter 1786) iii iv ABSTRACT New Zealand’s invertebrates are characterised by extraordinary levels of endemism and a tendency toward gigantism, flightlessness and longevity. These characteristics have resulted in a high vulnerability to introduced mammals (i.e. possums, rats, mice, and stoats) which are not only a serious threat to these invertebrates, but have also altered food web interactions over the past two-hundred years. The establishment of fenced reserves and the aerial application of 1080 toxin are two methods of mammal control used in New Zealand to exclude and reduce introduced mammals, respectively. Responses of ground-dwelling invertebrates to mammal control, including a consideration of trophic cascades and their interactions, remain unclear. However, in this thesis, I aimed to investigate how changes in mammal communities inside and outside a fenced reserve (ZEALANDIA, Wellington) and before-and-after the application of 1080 in Aorangi Forest, influence the taxonomic and trophic abundance, body size and other traits of ground-dwelling invertebrates on the mainland of New Zealand. I also tested for effects of habitat variables (i.e. vegetation and elevation), fluctuations in predator populations (i.e.
