This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The subfamily Centrotinae is the largest and only cosmopolitan subfamily within the treehopper family Membracidae (Insecta: Hemiptera: Membracidae). As the first comprehensive morphological study of the subfamily, this work includes: (a) phylogenetic analyses, (b) illustrated taxonomic keys and descriptions for identifying 23 tribes (6 new) and 2 unplaced genera, (c) new synonymies (1 generic, 11 tribal, 1 subfamilial), (d) a new lectotype designation, and (e) 5 new combinations. Of 216 genera here included in the subfamily, 207 are placed in tribes, 2 are unplaced but have known affinities, and 7 are too poorly known for placement. One genus formerly placed in the Centrotinae is placed as Membracidae, incertae sedis. Phylogenetic analyses were performed based on 116 morphological characters from the head, thorax, and abdomen of both sexes. These analyses (1 overall analysis of 24 tribes and 8 analyses of the larger tribes) resulted in a single most parsimonious tree showing a basal clade with one New World tribe, followed by two major clades--each with New World components basally followed by Old World components. These analyses demonstrated that the most recent classifications included numerous para- or polyphyletic tribes. Consequently, the tribal placements of 108 genera are changed so that all tribes are monophyletic. As here defined, the subfamily Centrotinae is also a monophyletic group supported by the synapomorphy of the presence of abdominal inornate pits, each with a lateral seta. Characters important in elucidating tribal relationships include features of: the male and female genitalia, the fore- and hind wings, the scutellum, leg chaetotaxy; and abdominal characteristics using scanning electron microscopy. Each tribal diagnosis and description is followed by notes on ecology and distribution, a list of included genera, specimens examined, and discussions of phylogeny and morphological characters. For most genera, the head, pronotum, wings, legs, male an.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research examines the phylogeny of the tribes of the leafhopper subfamily Typhlocybinae using both morphological, 73 binary and multistate characters, and molecular, 16S rDNA and Histone (H3), evidence. Seventy-five taxa were included in the morphological study, and 48 were included in the molecular analysis. The combined, total evidence, analysis used 48 taxa common to both sets of data. Results of the total evidence analyses suggested 4 tribes with the following topology: Alebrini + (Empoascini + Typhlocybini) + (Dikraneurini including subtribe Erythroneurina). This topology does not completely resemble any of the last century's major typhlocybine works, but comes closest to Dr. Young's 1952 work. Based on the results of these analyses, a revised classification is proposed. A key is provided to distinguish the tribes, and each is described with notes on distribution and evolutionary relationships, a list of the included genera (current to Feb. 2007), and illustrations of key morphological characters.

He synthesizes the scattered literature about social phenomena across the arthropod phylum: beetles and bugs, caterpillars and cockroaches, mantids and membracids, sawflies and spiders.
Download or read book Phylogeny and Systematics of the Leafhopper Subfamily Ledrinae Hemiptera Cicadellidae written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ledrinae represent a relatively small subfamily within the very large and diverse leafhopper family Cicadellidae. Prior to this study, the subfamily contained approximately 450 species in 5 tribes and 73 genera distributed worldwide, but primarily in Australia, Africa, and the Indomalayan region. Several authors have suggested Ledrinae are not monophyletic, and recent studies based on molecular and morphological data have called the existing classification into question. The goals of this study were to collect and analyze morphological data under rigorous phylogenetic criteria in order to test the monophyly of Ledrinae, provide robust definitions for the subfamily and its tribes, and provide a phylogenetic framework for understanding relationships among these leafhoppers. New phylogenetic hypotheses are presented here regarding the monophyly of Ledrinae and its included tribes. A total of 235 morphological characters were coded for 60 species from 31 genera in the tribes Ledrini and Petalocephalini, 5 species from the tribes Stenocotini, Thymbrini, and Xerophloeini, and 10 species selected as outgroups from various other cicadellid subfamilies. Data were analyzed in PAUP* and resulted in a single completely resolved topology with many well-supported nodes. Ledrinae, as previously defined, was found to be polyphyletic with respect to Stenocotini, Thymbrini, and various ledrine genera, which were placed with the outgroup taxa. Stenocotini and Thymbrini were placed with Tartessinae, agreeing with results of other recent studies. Rubria, Hespenedra, and the Afrorubria genus group formed independent lineages within Ledrinae. Xerophloeini was placed as a basal lineage within Ledrinae closely associated with the Afrorubria group. Ledrini and Petalocephalini, as previously defined, did not form monophyletic lineages, but were randomly interspersed with respect to one another. Stenocotini and Thymbrini are here removed to the subfamily Tartessinae, and Petalocephalini is mad.

Book excerpt: Offering a complete accounting of the insects of North America, this handbook is an up-dated edition of the first handbook ever compiled in the history of American entomology. By using American Insects, A Handbook of the Insects of America North of Mexico, Second Edition, readers can quickly determine the taxonomic position of any species, genus, or higher taxon of insect known to occur in America and Canada. Every order, family, and genus is conveniently numbered and indexed, making this volume the only complete single source for all of the names of orders, families, and genera currently available. This book fills the need for an accurate way to identify, with the several hundred drawings and photos, the common insects of all orders. Now there is a tool available to those working without a major collection and library; and those who would like to have a general knowledge of insect life without becoming overwhelmed by the vast number of minute insect species. This usable guide provides sizes, shapes, color patterns and salient features of some species of each major family by pointing out those groups most likely to be encountered, including all North America pests. What's New in this Edition? Researchers in many orders use the results of cladistics, a new tool for determining the relationship of orders, families, genera, and species of organisms, including plants as well as animals Specialists have provided lengthy lists of generic changes Many of the identification keys have been revised by adding more illustrations and making sure all description terms are in the Glossary The bibliographies of each Order section have been updated to include all important works that have appeared since the original edition
