Book Description
Cladistic analysis based on internal male female reproductive characters and external characters is used to group exemplar taxa in the carabid tribe Platynini. A classification, key to genera in North America, and a key to species groups of Agonum in North America north of Mexico are presented. The Agonum extensicolle species group comprises seven species: A. cyanope (Bates); A. extimum Liebherr, n.sp.; A. parextimum Liebherr n. sp.; A. texanum (LeConte); A. extensicolle (Say); A. decorum (Say); A. elongatulum (Dejean). Analyses of infraspecific geographic variation show: 1 ) A. texanum is biometrically uniform over the center of its range whereas individuals from outlying populations deviate in several measurements; 2) A. extensicolle is a variable species, with clinal changes in biometry and color ocurring across its range; 3) A. decorum is polymorphic for color and setation, and clinally variable in biometric characters. Across the group, flight apparatus development is inversely correlated with the amount of genetic heterogeneity measured by starch-gel electrophoresis. Electrophoretic, qualitative morphological, and biometric data are used to estimate phylogenetic relationships in the A. extensicolle group. The electrophoretic and morphological data produce compatible estimates of phylogeny. The biometric data are incompatible with the other data and are judged less useful for estimation of affinities. Distributional data are utilized in conjunction with the proposed phylogeny to investigate speciation events in the group. The principal mechanism is allopatric speciation brought about by vicariance across the lowlands of southeastern Arizona; the Cochise filter barrier. A second pattern involves a peripheral isolate of Antillean stock diverging on the Florida peninsula. A third speciation event involves a habitat shift in which a lowland desert form produced a species which now inhabits the pine-oak zone in the Sierra Madre Occidental. The area-taxon relationships are compared with those in other groups. Based on an electrophoretic clock calibrated using data from Drosophila, the timing of the initial speciation event in the group is estimated at 6-12 million years b.p. Other speciation events occurred throughout the Pliocene and Pleistocene, with the most recent divergence of A. decorum and A. elongatulum estimated at less than two million years b.p.

Book Description
The African continent has a rich fauna of insects, many of which are unstudied. This monograph treats one such group known as the small carpenter bees. Thirteen biological species in a new genus are described and a key for identification and details of their nests and natural enemies are given.

Book Description
This volume concludes the taxonomy and classification of the family Cerambycidae of America north of Mexico. This part includes the remainder of the subfamily Lamiinae, tribes Acanthocinini, Cyrtinini, Saperdini, Phytoeciini, Tetraspini, and Hemilophini. The 32 genera and 138 species are all fully described with keys included to separate all taxa. Complete synonymical bibliographies are presented along with 54 illustrations.

Book Description
The third in a trilogy of global overviews of conservation of diverse and ecologically important insect groups. The first two were Beetles in Conservation (2010) and Hymenoptera and Conservation (2012). Each has different priorities and emphases that collectively summarise much of the progress and purpose of invertebrate conservation. Much of the foundation of insect conservation has been built on concerns for Lepidoptera, particularly butterflies as the most popular and best studied of all insect groups. The long-accepted worth of butterflies for conservation has led to elucidation of much of the current rationale of insect species conservation, and to definition and management of their critical resources, with attention to the intensively documented British fauna ‘leading the world’ in this endeavour. In Lepidoptera and Conservation, various themes are treated through relevant examples and case histories, and sufficient background given to enable non-specialist access. Intended for not only entomologists but conservation managers and naturalists due to its readable approach to the subject.

Book Description
Volume One of the thoroughly revised and updated guide to the study of biodiversity in insects The second edition of Insect Biodiversity: Science and Society brings together in one comprehensive text contributions from leading scientific experts to assess the influence insects have on humankind and the earth’s fragile ecosystems. Revised and updated, this new edition includes information on the number of substantial changes to entomology and the study of biodiversity. It includes current research on insect groups, classification, regional diversity, and a wide range of concepts and developing methodologies. The authors examine why insect biodiversity matters and how the rapid evolution of insects is affecting us all. This book explores the wide variety of insect species and their evolutionary relationships. Case studies offer assessments on how insect biodiversity can help meet the needs of a rapidly expanding human population, and also examine the consequences that an increased loss of insect species will have on the world. This important text: Explores the rapidly increasing influence on systematics of genomics and next-generation sequencing Includes developments in the use of DNA barcoding in insect systematics and in the broader study of insect biodiversity, including the detection of cryptic species Discusses the advances in information science that influence the increased capability to gather, manipulate, and analyze biodiversity information Comprises scholarly contributions from leading scientists in the field Insect Biodiversity: Science and Society highlights the rapid growth of insect biodiversity research and includes an expanded treatment of the topic that addresses the major insect groups, the zoogeographic regions of biodiversity, and the scope of systematics approaches for handling biodiversity data.
