P. O. Box 141874 Gainesville, FL 32614-1874 USA http://www.centerforsystematicentomology.org/ Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published on any non-marine arthropod. Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. In- secta Mundi publishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources including the Zoological Record, CAB Abstracts, etc. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an individual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology. Managing editor: Paul E. Skelley, e-mail: [email protected] Production editors: Michael C.

The mirine plant bug Tropidosteptes forestierae, new species (Hemiptera: Miridae) is described from Collier County, Florida, where it was found causing serious injury to an extensive ornamental hedge of Florida swampprivet, Forestiera segregata (Jacq.) Krug and Urb. (Oleaceae). Adult male and female, fifth instar, and egg are described. Color images of the adults, nymph, egg, and injury; scanning photomicrographs of selected adult structures; and illustrations of male genitalia are provided. A key to help distinguish the 16 species of Tropidoste- ptes known to occur in the southeastern United States is given. Key words. Heteroptera, Miridae, Mirinae, Tropidosteptes, new species, Florida, host, injury, Forestiera segregata Introduction Fifty-two species are currently included in the New World plant bug genus Tropidosteptes Uhler (Miridae) (Schuh 1995), most of which were previously placed in the synonymic genera Neoborus Distant and Xenoborus Reuter (Carvalho 1954, Kelton 1978). Of these, 37 species are known from the United States and Canada, with 25 recorded in eastern North America (Henry and Wheeler 1988). Although there are no comprehensive identification keys, Knight (1923) keyed the 13 species known from Con- necticut and vicinity; Blatchley (1926) gave a slightly modified version of Knight’s (1923) key to eastern U.S. species; Knight (1941) keyed 14 species from Illinois; and Kelton (1980) included nine species in his key to the species of the Canadian prairie provinces. Most North American species are associated with trees and shrubs in the family Oleaceae, espe- cially species of ash, Fraxinus spp. (Knight 1917), and several species in related genera, such as white fringe tree, Chionanthus virginicus L. (Knight 1927), and devilwood, Osmanthus americanus (L.) Benth. and Hook. f. ex A. Gray (Knight 1923, 1941). Two exceptions in the East are T. populi (Knight 1929), described and known only from Illinois on cottonwood (Populus deltoides Bartram ex March.), and T. quercicola (Johnston 1939), described from Texas on live oak (Quercus virginiana Mill.) and later re- ported from Florida (Halbert 2008). We note that although the latter species clearly is not congeneric with other species of Tropidosteptes, we are retaining it in the genus until the group can be revised. 1 2 • INSECTA MUNDI 0240, June 2012 HENRY, CALDWELL AND HALBERT Species of the genus typically feed on the abaxial leaf surface, resulting in tiny, tell-tale, white, chlorotic spots on the upper surfaces of the host’s foliage (Dickerson and Weiss 1916, Usinger 1945), frequently warranting chemical treatment (Wheeler and Henry 1974). Large populations may cause much more extensive chlorosis, leaf curling, and necrosis, resulting in dead or withered foliage that eventually may drop prematurely, sometimes resulting in total defoliation (Henry 1980; Wheeler 1982, 2001). In this paper, a new species of Tropidosteptes is described from a large population in Collier Co., Florida, that was found severely injuring an ornamental Florida swampprivet, Forestiera segregata (Jacq.) Krug and Urb. (Oleaceae) hedge, and a specimen taken in Miami-Dade Co. Color habitus images of the adult male and female, fifth-instar nymph, egg, and foliar damage, a diagnosis and description of the adult, fifth instar, and egg, scanning electron photomicrographs of selected structures, and il- lustrations of male genitalia are provided. The first key to the 16 species ofTropidosteptes occurring in the southeastern United States is given to help distinguish T. forestierae. Materials and Methods Color adult habitus images were captured using an EntoVision Imaging Suite that included a JVC KY-75 3CCD digital camera mounted to a Leica M16 zoom lens via a Leica z-step microscope stand. Multiple focal planes were merged using Cartograph 5.6.0 (Microvision Instruments, France) software. Scanning photomicrographs of selected adult structures were taken using a Zeiss EVO/15 scanning electron microscope at 6 kv. The specimen was mounted on a standard 13 mm stub and sputter coated. Habitat images were taken with a Nikon 995 Coolpix digital camera. Specimens are deposited in the Florida State Collection of Arthropods (FSCA), Florida Department of Agriculture and Consumer Services, Gainesville, Florida, and the National Museum of Natural His- tory (USNM) collection, Smithsonian Institution, Washington, D.C. We use the common name Florida swampprivet for Forestiera segregata, following the USDA, NRCS (2011) PLANTS Database, but also note that this plant is sometimes referred to more simply as Florida privet (e.g., Betrock’s Plant Finder 2011).
