Book Description
A revision and the first phylogenetic analysis of the widely distributed plant bug genus Tytthus is presented. All 24 species of this genus, including five described as new, prey exclusively on planthopper (Delphacidae) eggs, making them of great importance on agricultural monocots. Two species have been used successfully in biocontrol programs to suppress populations of sugarcane delphacid on sugarcane and brown planthopper on rice. All species of Tytthus are relatively small, but the tiny brachypterous males of one species, ranging from 1.08?1.30 mm long, rank it as possibly the world?s smallest known plant bug. Members of this genus are found in nearly all biogeographic regions, including 18 restricted to the Nearctic and Neotropics and three from the eastern Oriental and Indo-Pacific regions. There are also two Holarctic and one circumtropical (Afrotropical, Neotropical, and Oriental) species. A hypothesized relationship with several Nearctic plant bug genera suggests a New World origin for this group of important predatory bugs.

Book Description
True bugs (Heteroptera) are a diverse and complex group of plant-feeding and predatory insects important to food production, human health, the global economy and the environment. Within the nearly 43,000 species described around the world, Neotropical true bugs are particularly diverse, and much remains to be discovered about their biology and relations with other species. Inspired by the need for a comprehensive assessment, True Bugs (Heteroptera) of the Neotropics is the most complete and thorough review ever published. Experts in each of the seven infraorders have drawn together the scattered literature to provide detailed treatments of each major taxon. The most common and important species as well as select lesser known species in each major family are covered, highlighting morphology, classification, biology and ecology. The numerous color illustrations highlight key species and their adaptations, and importance to basic and applied sciences is discussed. Each chapter is based on an up-to-date review of the literature, and with a bibliography of more than 3,000 references, readers are presented with an unprecedented and vital and timely account of the true bugs of the Neotropical Region.

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.

Book Description
"The genus Rhinacloa Reuter is revised. Thirty-seven species are included, 17 of which are described as new. Campylomma cardini Barber and Bruner, Europiella mella Van Duzee, Psallus incaicus Carvalho and Gomes, Psallus insularis Carvalho, Psallus longirostris Carvalho, Psallus usingeri Carvalho and Sthenarus basalis Reuter are transferred to Rhinacloa. The following new synonymies are created: Rhinacloa antennalis (Reuter) = Rhinacloa melanotelus Reuter; Rhinacloa clavicornis (Reuter) = Rhinacloa subpallicornis Knight and Rhinacloa lepagei Carvalho; Rhinacloa forticornis Reuter = Psallus minutulus Reuter and Rhinacloa incerta Reuter; Rhinacloa basalis (Reuter), new combination = Rhinacloa pallida Reuter, Rhinacloa pusillus (Knight), and Rhinacloa castanea Carvalho; Rhinacloa pallidipes Maldonaldo = Lepidopsallus riodocensis Carvalho and Rhinacloa punctipes Maldonaldo. Demarata mirifica Distant is treated as a species incertae sedis. Rhinacloa araguaiana Carvalho is transferred to Paramixia Reuter (Pilophorini). Lygus ordinatus Distant is placed in Ellenia Reuter (Phylini). Illustrations are presented for the antennae and male genitalic structures of most known Rhinacloa species; scanning electron micrographs are presented for the pretarsus and scale-like setae of many species. A key to separate the included species is included. A phylogenetic analysis of the species is presented, using Campylomma verbasci Meyer-D|r, Microphylidea prosopidis Knight, and Nigrimiris pallipes Carvalho and Schaffner for outgroup comparison. Distributional maps are provided for all species, indicating a range for Rhinacloa from the southwestern United States, the Caribbean including the Florida Keys, (with three widely distributed species occurring in Florida), the Galapagos Islands, and south to northern Argentina and central Chile. Rhinacloa forticornis is introduced into Hawaii"--Page 382

Book Description
"The western Nearctic species of the cosmopolitan genus Phytocoris Fallén are revised. Ecertobia Reuter and Pallacocoris Reuter are proposed as new junior synonyms of Phytocoris. One-hundred and ninety-nine species are recognized including four that also occur in the Palearctic region. The species are distributed among 20 newly proposed species-groups, primarily on the basis of head morphology, dorsal vestiture, and characteristics of the male genitalia. Seventy-eight new species are described and the following new synonymies are proposed (senior synonym first): acaciae Knight = minuendus Knight; calli Knight = laticeps Knight; deserticola Knight = lineatellus Knight; empirensis Knight = rinconae Knight; fraterculus Van Duzee = westwoodi Bliven; fuscipennis Knight = longirostris Knight; geniculatus Van Duzee = blackwelli Bliven; interspersus Uhler = viridescens Knight; juniperanus Knight = chiricahuae Knight, flaviatus Knight, santaritae Knight; ketinelbi Bliven = kahtahbi Bliven; knowltoni Knight = albertae Knight, elongatus Knight; laevis (Uhler) = rolfsi Knight; maritimus Van Duzee = sequoiae Bliven; neglectus Knight = yuroki Bliven; nigrifrons Van Duzee = abiesi Knight, tehamae Bliven; relativus Knight = albiscutellatus Knight; stellatus Van Duzee = arcatae Bliven, tinctus Knight; stitti Knight = albiceps Knight, merinoi Knight; strigosus Knight = flavellus Knight; sublineatus Knight = subcinctus Knight, tanneri Knight; tenuis Van Duzee = gracillatus Knight; ventralis Van Duzee = contrastus Knight, ephedrae Knight, quadricinctus Knight; vinaceus Van Duzee = hyampom Bliven; yollabollae Bliven = albiclavus Knight, montanae Knight, taos Knight. Illustrations are provided for the male genitalia of all species, and scanning electron micrographs are presented for the head, pretarsus, and dorsal vestiture of representative species. Dorsal habitus illustrations are provided for representatives of nine species-groups. A detailed diagnosis and description are included for the genus and each of the 20 species-groups. A key to species groups is given, as well as keys to the species of each group. All species treatments include a diagnosis and summary information on biology, host plant associations, and distribution. Detailed descriptions and specific locality data are included only for the new species. Phytocoris species diversity and endemism are greatest in shrub and steppe, and desert communities of the southwestern United States. The majority of western Nearctic species are host-specific inhabitants of trees and shrubs, but a few ubiquitous species are known to breed on grasses and herbaceous plants. Many species occurring on woody plants appear to be inhabitants of bark. The nymphs and adults of most species are believed to be primarily predaceous. Nearctic and Palearctic species have been observed feeding on small, soft-bodied insects and mites, including several important pests of forests and orchards"--P. 3.
