Afrotropical flea beetle genera: a key to their identification, updated catalogue and biogeographical analysis (Coleoptera, Chrysomelidae, Galerucinae, Alticini)


Book Description

The genera of Chrysomelidae Galerucinae Alticini from the Afrotropical region are revised. The monograph includes a key for their identification, habitus photos of all genera, microscope and scanning electron micrographs of many diagnostic morphological characters and an updated annotated catalogue with biogeographical notes that including new distributional data for Sub-Saharan Africa and Madagascar. The following new synonymies are established: Aphthona Chevrolat, 1836 = Ethiopia Scherer, 1972; Sanckia Duvivier, 1891 = Eugonotes Jacoby, 1897; Eurylegna Weise, 1910a = Eurylegniella Scherer, 1972; Kimongona Bechyn?, 1959a = Mesocrepis Scherer, 1963; Diphaulacosoma Jacoby, 1892a = Neoderina Bechyn?, 1952; Sesquiphaera Bechyn?, 1958a = Paropsiderma Bechyn?, 1958a; Podagrica Chevrolat, 1836 = Podagricina Csiki in Heikertinger & Csiki, 1940; Amphimela Chapuis, 1875 = Sphaerophysa Baly, 1876a. The genera Buphonella Jacoby, 1903 and Halticopsis Fairmaire, 1883 are transferred to tribe Galerucini; the genus Biodontocnema Biondi, 2000 stat. prom. is considered to be valid and reinstated at generic level. New combinations are also proposed. Finally a zoogeographical analysis of the flea beetle fauna in the Afrotropical region is provided.




Research on Chrysomelidae 4


Book Description

The mode of life of leaf beetles (Chrysomelidae) might appear less interesting, as compared to free and fast roaming and hunting ground beetles (Carabidae), eusocial bees (Apidae), or so many other behaviourally fascinating insects. Chrysomelids generally hatch from eggs, which are typically laid onto their food plants. Larvae eat, moult, and pupate on or very close to these plants. Following emergence as adults reproduction often proceeds without complex courting and, in most cases, without eating much or moving for longer distances. All of this is quite insect-like and seemingly pedestrian. Nevertheless, the mechanisms of host plant selection, the wide range of defensive devices, the multifariousness of shapes and the gaudiness of colours of their body ? to name just a few phenomena of their biology ? continuously fascinate quite a number of scientists, let aside many other beetle enthusiasts. Every four years, in connection with the International Congresses of Entomology, an informal group of leaf beetle workers meets for an International Symposium on the Chrysomelidae. Last time, we met on August 23, 2012, in Daegu, South Korea for the 24th International Congress of Entomology. Of the seven papers therein presented, four are, in extended and elaborated versions, published in the present volume. Three more papers on Chrysomelidae have been submitted independently and are included here as well. The present volume 4 of the series Research on Chrysomelidae is the second published as a special issue of ZooKeys. Publishing with Pensoft?s ZooKeys is not only fast and affordable, but also allows the inclusion of colour illustrations ad libitum, in both the printed and digital versions, so that the authors can easily share their excitement on their scientific objects with their readers. We, the editors, are glad to present this volume and hope that it will be valued not only for its scientific value but also attract the attention of non-chrysomelidologists to the fascinating world of leaf beetles. Hopefully, many such volumes will follow, so that our series will develop into an attractive forum for sharing news about a scientifically interesting, economically important, and emotionally rewarding group of insects.




Research on Chrysomelidae


Book Description

There are an estimated 40,000 species of chrysomelids, or leaf beetles, worldwide. These biologically interesting and often colorful organisms, such as the tortoise beetles, have a broad range of life histories and fascinating adaptations. For example, there are chrysomelids with shortened wings (brachypterous) and elytra (brachelytrous), other species are viviparous, and yet other leaf beetles have complicated anti predator-parasitoid defenses. Some species, such as corn rootworms (several species in the genus "Diabrotica") constitute major agricultural crop pests. "Research on Chrysomelidae 2" is a the second volume of a series of volumes on the Chrysomelidae edited by Jolivet, Santiago-Blay, and Schmitt.

Novel Aspects of the Biology of Chrysomelidae


Book Description

Chrysomelidae, along with Curculionidae and Bruchidae, are the most important phytophagous Coleoptera. At least 37,000 species of leaf beetles belonging to 19 subfamilies have now been described, and more probably remain to be discovered, especially in the tropics. Many species are familiar agricultural pests. The Colorado potato beetle, the cereal beetle, flea beetle and the corn root worms are but a few of the well known pests. Because of the economic importance and biological diversity, chrysomelids are an important taxonomic group for scientific inquiry. This book is divided into eight parts, entitled palaeontology, larvae and larval biology, trophic selection, genetics and evolution defence mechanisms, anatomy and reproduction, pathogens and natural enemies, and general studies in biology. The biologies of agricultural and forestry pests, Leptinotarsa, Plagiodera, Entomoscelis, Paropsis, Mecistomela and Aspidomorpha are dealt with in detail. Others, such as Timarcha and those in the poorly known Megalopodinae, are covered in Part VIII. In this volume the American, European, Asian and Australian fauna occupy the greatest part. This volume, together with Biology of Chrysomelidae (1988), provides a comprehensive coverage and helps to complete the picture of chrysomelid biology.




Biology of Chrysomelidae


Book Description

As in most groups of insects, scientific research on the Chrysomelidae began in Europe in 1758, with the description of a few genera and species by the Scandinavian entomologists C. von Linne, I.C. Fabricius, and others. As the 19th century dawned, many systematic entomologists took up the study of chrysomelid beetles, together with other groups of beetles, and many new species and genera were described from all parts of the world. This trend has, of course, continued down to the present time. However, researches on the Chrysomelidae did not remain restricted to systematics, and many new lines of study have been followed, especially in the present century, by workers who have benefitted from the advances made in related fields of pure and applied entomology. Much has been achieved in the study of the Chrysomelidae, as elsewhere, and it is the aim of the present book to provide a summary and guide to these achievements. It is also to be expected that this book will provide a stimulus for further studies on the Chrysomelidae, so that we can anticipate continuing progress in our knowledge and understanding of this group through the endeavours of an ever-increasing number of scientists. I offer my congratulations to all concerned in the preparation of this book and my best wishes for its success.




Evolutionary Biogeography


Book Description

"Rather than favoring only one approach, Juan J. Morrone proposes a comprehensive treatment of the developments and theories of evolutionary biogeography. Evolutionary biogeography uses distributional, phylogenetic, molecular, and fossil data to assess the historical changes that have produced current biotic patterns. Panbiogeography, parsimony analysis of endemicity, cladistic biogeography, and phylogeography are the four recent and most common approaches. Many conceive of these methods as representing different "schools," but Morrone shows how each addresses different questions in the various steps of an evolutionary biogeographical analysis. Panbiogeography and parsimony analysis of endemicity are useful for identifying biotic components or areas of endemism. Cladistic biogeography uses phylogenetic data to determine the relationships between these biotic components. Further information on fossils, phylogeographic patterns, and molecular clocks can be incorporated to identify different cenocrons. Finally, available geological knowledge can help construct a geobiotic scenario that may explain how analyzed areas were put into contact and how the biotic components and cenocrons inhabiting them evolved. Morrone compares these methods and employs case studies to make it clear which is best for the question at hand. Set problems, discussion sections, and glossaries further enhance classroom use."--Publisher's description.




New Developments in the Biology of Chrysomelidae


Book Description

This book summarizes what is actually known about the biology of Leaf Beetles. It is the most recent study in the field. As we are well aware, Chrysomelidae, one of the three largest families of beetles, are of great economic importance since they can be a serious pest to crops or, on the other hand, can be used to destroy imported weeds. This is due to the selectivity of their feeding preferences. In this way, Chrysomelidae are an invaluable tool for studying plant selection mechanisms. The many and varied topics dealt with in this book cover almost all aspects of phylogeny, classification, paleontology, parasitology, biogeography, defenses, population biology, genetics and biological control as well as many other subjects. The most renowned specialists in these fields have been chosen to put together a diverse, state-of-the-art publication. Few beetle families have been studied in such detail as the Chrysomelids. This is not only due to their economic importance, but also to their incredible variety of forms and behaviors. There are no less than 40,000 species currently in existence worldwide, but probably 100,000 species have existed since the Jurassic, when they first came into being with the Cycadoids and other primitive plant families, later to diversify during the Cretaceous with the advent of flowering plants.




General Distribution of the Flea Beetles in the Palaearctic Subregion (Coleoptera, Chrysomelidae, Alticinae)


Book Description

This supplement comes not only to correct the inaccuracies and mistakes in the authors monograph of 1997, but also to update the nomenclature, taxonomy and distribution of the Alticinae, or flea beetles, in the Palaearctic subregion. As a result, 83 names of flea beetles are eliminated, mostly as synonyms, while 113 species are added. So the total number of species or subspecies has increased from 1,358 to 1,388. The following three genera are added to the regional list: Aeschrocnemis, Cyrsylus and Heyrovskya. Blagoi Gruev, born 1936, is a lecturer of general biogeography at the University of Plovdiv, the author of the first textbook on this subject in Bulgaria, who also provided an original biogeographical division of the country. He has described 64 new taxa of Chrysomelidae from various parts of the Palaearctic, Oriental and Afrotropical realms. Manfred Doberl, born 1933, has devoted 40 years of his life to teaching and entomology. He has also described numerous new Palaearctic and Oriental flea beetles, published in more than 30 papers.




Biology of Leaf Beetles


Book Description

This text provides a tour through the extensive literature on one of the largest families of insects, the family of the leaf beetles, or the chrysomelidae. It is anintroduction to their biology and also, given their phytophagy, to their agricultural importance. Many chrysomelids are crop pests. An account of chrysomelid food has therefore been included, and interesting deviations from their phytophagy have been described. Also covered are the various defence mechanisms exhibited by leaf beetles against parasites and predators.
