Revisions of Dioclerus, Harpedona, Mertila, Myiocapsus, Prodromus, and Thaumastomiris (Heteroptera, Miridae, Bryocorinae, Eccritotarsini). Bulletin of the AMNH ; v. 187, article 1

99 p. : ill., maps ; 26 cm.Includes bibliographical references (p. 97-99)."The following six genera of Old World Eccritotarsini (Bryocorinae) are revised, including taxa distributed from tropical west Africa to India, southeast Asia, and east to New Guinea and the Solomon Islands in the tropical western Pacific: Dioclerus Distant, Harpedona Distant, Mertila Distant, Myiocapsus Poppius, Prodromus Distant, Thaumastomiris Kirkaldy. Fifty-nine species are treated in detail, 34 of which are described as new. The genus Maurocoris Poppius is synonymized with Harpedona Distant and Prodromopsis Poppius is renewed as a synonym of Prodromus Distant. The following species are synonymized (senior synonym listed last): Mertila brevicornis Poppius = Mertila malayensis Distant; Prodromopsis basalis Poppius, Prodromopsis cuneatus (Distant), Prodromopsis scutellaris Poppius, Prodromus cochinensis Odhiambo = Prodromus clypeatus Distant; Prodromus pedunculatus Odhiambo = Prodromus oculatus (Poppius); Prodromus flavonotus Odhiambo = Prodromus thaliae China. The following new combinations are created: Maurocoris unicolor Poppius = Harpedona unicolor; Prodromus aethiopicus Poppius = Duducoris aethiopicus. Prodromus alboviridescens (Motschulsky) is assigned the status of nomen dubium. Harpedona fulvigenis (Poppius), Prodromus joveri Delattre, and Prodromus nimbus Delattre were not examined in conjunction with the present study. A dorsal habitus illustration is provided for each genus. Scanning electron micrographs of the metathoracic scent efferent system, pretarsus, and other structures are presented for most genera. Line drawings of the male genitalia and distribution maps are given for all species. A cladistic analysis of species is performed for each genus and keys for the identification of species are provided. A revised diagnosis and description of each genus are included, and descriptions or redescriptions given for all species"--P. 4

Revision and cladistic analysis of the Holarctic genus Atractotomus Fieber (Heteroptera, Miridae, Phylinae). Bulletin of the AMNH ; no. 198

88 p. : ill. ; 26 cm.Includes bibliographical references (p. 86-88)."The Holarctic genus Atractotomus Fieber is revised. Lepidopsallus Knight and Microphylidea Knight are relegated to synonymy with Atractotomus. Thirty-seven species are recognized, including 17 new species from the Nearctic region. Microphylidea prosopidis Knight, Psallus kolenatii (Flor), Rhinacloa nigripennis Schuh and Schwartz, and six species of Lepidopsallus (arizonae Knight, atricolor Knight, miniatus Knight, ovatus Knight rubidus (Uhler), tuthilli Knight) are transferred to Atractotomus. Atractotomus amygdali Wagner, A. mali (Meyer-Dür), A. rhodani Fieber, and A. vireti Wagner are assigned the status of species incertae sedis. Atractotomus femoralis Fieber and A. spissicornis (Schrank) are declared nomina dubia. Atractotomus crataegi and the remaining eight species of Lepidopsallus (australis Blatchley, claricornis Knight, hesperus Knight, longirostris Knight, minusculus Knight, olseni Knight, pini Knight, rostratus Knight) are transferred to Phoenicocoris Reuter. The following species synonymies are proposed (senior synonym first): Atractotomus albidicoxis Reuter = Lepidopsallus monticola Knight; Atractotomus balli Knight = Atractotomus purshiae Froeschner and Lepidopsallus californicus Knight; Atractotomus magnicornis (Fallén) = Atractotomus magnicornis buenoi Knight; Atractotomus miniatus (Knight) = Lepidopsallus nyssae Johnston; Atractotomus ovatus (Knight) = Lepidopsallus nicholi Knight; Atractotomus parvulus Reuter = Atractotomus mirificus Woodroffe; Atractotomus persquamosus Seidenstücker = Atractotomus brunomassai Carapezza. Illustrations and/or photographs are provided for the antennae and male genitalic structures of all species of Atractotomus. Scanning electron micrographs are presented for the scalelike setae, metafemur, and pretarsus of representative species of Atractotomus and related genera. Separate keys are provided for the Nearctic and Palearctic members of the genus. A phylogenetic analysis of species is presented using Psallus ancorifer (Fieber) for outgroup comparison. Three species groups are recognized from the resulting species phylogeny. An analysis of host plant associations suggests that Atractotomus was primitively associated with conifers, but shifted to legume feeding early in the evolution of the genus. In the Nearctic region, this was followed by separate shifts to feeding on Quercus, Salix, and Rhamnaceae + Rosaceae. Species diversity and endemism are greatest in parts of east-central and south-central Mexico. Species with restricted distributions also occur in southeastern Arizona, the Rocky Mountains, and upland regions of the Pacific coast states and Baja California. The phylogenetic analysis of species indicates a strong relationship between taxa occurring in the American Southwest and endemic species in central Mexico"--P. 4

Revision of the mirine genus Phytocoris Fallén (Heteroptera, Miridae) for western North America. Bulletin of the AMNH ; v. 188, article 1

257 p. : ill., map ; 26 cm.Includes bibliographical references (p. 248-251) and indexes. Indexes compiled by the author and Michael D. Schwartz."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
