Insect Classification Standards 2020
RECOMMENDED INSECT CLASSIFICATION FOR UGA ENTOMOLOGY CLASSES (2020) In an effort to standardize the hexapod classification systems being taught to our students by our faculty in multiple courses across three UGA campuses, I recommend that the Entomology Department adopts the basic system presented in the following textbook: Triplehorn, C.A. and N.F. Johnson. 2005. Borror and DeLong’s Introduction to the Study of Insects. 7th ed. Thomson Brooks/Cole, Belmont CA, 864 pp. This book was chosen for a variety of reasons. It is widely used in the U.S. as the textbook for Insect Taxonomy classes, including our class at UGA. It focuses on North American taxa. The authors were cautious, presenting changes only after they have been widely accepted by the taxonomic community. Below is an annotated summary of the T&J (2005) classification. Some of the more familiar taxa above the ordinal level are given in caps. Some of the more important and familiar suborders and families are indented and listed beneath each order. Note that this is neither an exhaustive nor representative list of suborders and families. It was provided simply to clarify which taxa are impacted by some of more important classification changes. Please consult T&J (2005) for information about taxa that are not listed below. Unfortunately, T&J (2005) is now badly outdated with respect to some significant classification changes. Therefore, in the classification standard provided below, some well corroborated and broadly accepted updates have been made to their classification scheme. Feel free to contact me if you have any questions about this classification. -

Comparative Cytogenetics 9(3): 435–450. doi: 10.3897/CompCytogen.v9i3.5160 Abstract Tropidacris Scudder, 1869 is a genus widely distributed throughout the Neotropical region where specia- tion was probably promoted by forest reduction during the glacial and interglacial periods. There are no cytogenetic studies of Tropidacris, and information allowing inference or confirmation of the evolutionary events involved in speciation within the group is insufficient. -
New Canadian and Ontario Orthopteroid Records, and an Updated Checklist of the Orthoptera of Ontario
Checklist of Ontario Orthoptera (cont.) JESO Volume 145, 2014 NEW CANADIAN AND ONTARIO ORTHOPTEROID RECORDS, AND AN UPDATED CHECKLIST OF THE ORTHOPTERA OF ONTARIO S. M. PAIERO1* AND S. A. MARSHALL1 1School of Environmental Sciences, University of Guelph, Guelph, Ontario, Canada N1G 2W1 email, [email protected] Abstract J. ent. Soc. Ont. 145: 61–76 The following seven orthopteroid taxa are recorded from Canada for the first time: Anaxipha species 1, Cyrtoxipha gundlachi Saussure, Chloroscirtus forcipatus (Brunner von Wattenwyl), Neoconocephalus exiliscanorus (Davis), Camptonotus carolinensis (Gerstaeker), Scapteriscus borellii Linnaeus, and Melanoplus punctulatus griseus (Thomas). One further species, Neoconocephalus retusus (Scudder) is recorded from Ontario for the first time. An updated checklist of the orthopteroids of Ontario is provided, along with notes on changes in nomenclature. Published December 2014 Introduction Vickery and Kevan (1985) and Vickery and Scudder (1987) reviewed and listed the orthopteroid species known from Canada and Alaska, including 141 species from Ontario. A further 15 species have been recorded from Ontario since then (Skevington et al. 2001, Marshall et al. 2004, Paiero et al. 2010) and we here add another eight species or subspecies, of which seven are also new Canadian records. Notes on several significant provincial range extensions also are given, including two species originally recorded from Ontario on bugguide.net. Voucher specimens examined here are deposited in the University of Guelph Insect Collection (DEBU), unless otherwise noted.

Orthoptera: Caelifera)
Insect Systematics & Evolution 44 (2013) 241–260 brill.com/ise Re-evaluation of taxonomic utility of male phallic complex in higher-level classification of Acridomorpha (Orthoptera: Caelifera) Hojun Song* and Ricardo Mariño-Pérez Department of Biology, University of Central Florida, 4000 Central Florida Boulevard Orlando, FL 32816, USA *Corresponding author, e-mail: [email protected] Published 25 October 2013 Abstract The current higher classification of the orthopteran superfamily group Acridomorpha is largely based on interpretation of male phallic structures. Internal male genitalia have been considered as an excellent taxonomic character because of a widespread belief that they are less subject to selective pressures from environment, and thus more stable than external characters. Furthermore, based on a notion that evolu- tion proceeds from simple to complex, early taxonomists who shaped the higher classification of Acridomorpha considered those groups with less differentiated and membranous phallic structures as primitive and used this notion to deduce a phylogeny of Acridomorpha. In this study, we test these ideas based on a cladistic analysis of male phallic structures and a character optimization analysis to assess the level of homoplasy and synapomorphy for those phallic characters that have been traditionally used for the Acridomorpha systematics. We also perform an independent test of the phylogenetic utility of male phal- lic structures based on a molecular phylogeny. We show that while some phallic structures have strong phylogenetic signal, many traditionally used characters are highly homoplasious. However, even those homoplasious characters are often informative in inferring relationships. Finally, we argue that the notion that evolution proceeds in increasing complexity is largely unfounded and difficult to quantify in the higher-level classification of Acridomorpha. -
