The New World species of Chaenusa Haliday sensu lato are revised, and a diagnosis is provided for Chaenusa s.l. Four new species from North America, Chaenusa trumani Kula, Chaenusa virgili Kula, Chaenusa whartoni Kula, and Chaenusa woolleyi Kula, and two new species from South America, Chaenusa hirsutissima Kula and Chaenusa ireneae Kula, are described. Chaenusa americana (Riegel), new combination and Chaenusa saxicola (Riegel), new combination are transferred from Chorebidea Viereck. Chaenusa bergi (Riegel), revised combination is returned from Chorebidella Riegel. Chorebidea bessae Riegel is a new synonym of Cha. americana, and Chorebidea mcclurei Riegel is a new synonym of Cha. saxicola. Chaenusa anticostae Riegel and Chaenusa illinae Riegel are new synonyms of Chaenusa quadriceps (Ashmead). Chaenusa americana, Cha. bergi, Chaenusa californica Riegel, Cha. quadriceps, Chaenusa rossi Riegel, and Cha. saxicola are redescribed. Host and spatiotemporal distribution data are provided, including new host and distribution records. The status of several holotypes is discussed, and a key to the New World species of Chaenusa s.l. is provided.
Leptoglossus katiae Schaefer and Packauskas, n. sp., is described from northeastern Brazil. It belongs in the L. cinctus species group and is most similar to Leptoglossus cinctus (Herrich-Schaeffer), L. crassicornis (Dallas), and L. fasciatus (Westwood). It can be distinguished from these species, and from most other Leptoglossus species, by its small size (10.5–12.3 mm) and long rostrum (reaching onto the sixth abdominal sternum), as well as by other characters. Sexual dimorphism of the hind tibia and femur is discussed briefly.
A new species of Eremomusca, E. wakii, is described from specimens collected in Japan (Ayase City; 35°25.9′N, 139°25.9′E). For perspective, a diagnosis for Eremomusca is provided, and to facilitate identification a key to species of the genus, as well as figures of the head, thorax, abdomen, and wings, are provided.
The origins and status of Chrysolina staphylaea (Linnaeus), first recorded in North America in Halifax, Nova Scotia, Canada in 1897, is reviewed. Additional records from Nova Scotia and Newfoundland are reported which establish that the species is more widely distributed than has hitherto been known. The status of the species on the continent is discussed, as are possible modes of introduction, dispersal, and potential host plants.
Eupithecia sonora, new species, is described from Sonora, Mexico and compared with its closest phenotypic congener Eupithecia flavigutta (Hulst). Adults and male and female genitalia of both species are illustrated. Additional specimens have been collected in Arizona and New Mexico.
Strategus temoltzin, new species, from submontane scrub at 1,030–1,130 m altitude near Palmillas, Tamaulipas, Mexico, is described and illustrated. An updated key to the species of Strategus inhabiting Mexico is included.
Five new species, Anadasynus cameroonensis from Cameroon, Galaesus ugandaensis from Uganda, Pseudopendulinus naevillus from Cameroon and Spanish Guinea, Pseudopendulinus sordidus from Rwanda, and Pseudopendulinus validus from Central African Republic and Cameroon, are described. A key to the known species of Anadasynus, Galaesus, and Pseudopendulinus are included, and dorsal habitus illustrations, and drawings of antennae, and male genital capsule are provided.
A new species of fossil mosquito, Toxorhynchites (Toxorhynchites) mexicanus, is described from Mexican amber. This species differs from all extant species of the genus by having a strong bristle posteriorly on the postpronotum and it differs from all species of the subgenus Toxorhynchites by having the unique combination of a short rm index (1.3) and conspicuous caudal tufts of setae on the abdomen. This is the first record of the Old World subgenus Toxorhynchites in the New World.
Siemssenius sulcipennis Zhang and Yang, n. sp., from China is described and illustrations of the adult and the male aedeagus are provided. Pseudoliroetis trifasciataJiang, 1992, is transferred to Siemssenius (n. comb.). A key to all known species of Siemssenius is included.
Fifty-six species (23 genera) of treehoppers (Membracidae) are recorded from the vicinity of Little Orleans, Maryland, with date and host-plant data. Eleven of the species represent new state records for Maryland, bringing the total number of species recorded for the state to 81. These data document annual collecting efforts since 1993 by the authors and others in connection with the informal treehopper conferences initiated by the late T. K. Wood. Photographs are given for 12 species representing 7 genera.
Since the last revision of the Neotropical riodinid genus Theope Doubleday in 1999, several new Amazonian species have been discovered. These discoveries are summarized here. Two new species were described between 2002 and 2006, T. fayneli Gallard (nycteis group) and T. minialba Gallard (miscellaneous group), and an additional three new species are described here, T. tetrastigmoidesHall (tetrastigma group), T. harrisi Hall (hypoleuca group), and T. euselasina Hall (eurygonina group). The genus Theope now contains 73 species and, with the proposal of the eurygonina group for T. eurygonina Bates and T. euselasina, fifteen species groups. The recently proposed subspecies name minimus Gallard is here synonymized with T. fayneli (n. syn.).
The European lace bug Dictyonota fuliginosa Costa, a specialist on broom (Cytisus scoparius (L.) Link; Fabaceae), was first reported in North America from British Columbia in 1960, but subsequent Nearctic records have been limited to “Oregon” and that state's Willamette Valley. We provide the first specific U.S. records, including the first for Washington State; summarize information on its biology and distribution in Europe; and give notes on its seasonality in Oregon.
A total of 130 species of thrips occurring in Africa, Europe, and the Mediterranean region were intercepted by U.S. agricultural quarantine officers in shipments of plants and cut flowers at the various ports-of-entry in the United States from 1983 to 1999. Of the 24 most intercepted species of thrips encountered by port identifiers during this period, 10 of them were species of the genus ThripsLinnaeus, 1758 (T. tabaci Lindeman, T. fuscipennis (Haliday), T. major (Uzel), T. vulgatissimus (Haliday), T. meridionalis (Priesner), T. flavus Schrank, T. atratus (Haliday), T. simplex (Morison), T. nigropilosus Haliday, and T. australis (Bagnall)). This is Part III of a guide to the identification of thrips intercepted from those regions. Included are keys, line drawings, and scanning electron micrographs to help identify the 18 commonly intercepted species of the genus Thrips, characterized by the presence of ctenidia located posteriad of abdominal spiracle VIII.
Lilioceris lilii (Scopoli), the lily leaf beetle, is an introduced Palearctic leaf beetle now established in many parts of central and eastern Canada and in New England. It is a voracious feeder on plants in the genera Fritillaria and Lilium, a cause of concern in North America where it is found. The introduction history and bionomics of the species are briefly reviewed. Its distribution in the Maritime Provinces of Canada is detailed, focusing particularly on its rapid radiation during the past five years. Observations on dispersal phenology and longevity in the region are given. Concerns with respect to its recent spread to the native Canada lily, Lilium canadense, are expressed. Biocontrol measures and programs being pursued in the United States are noted in relation to options that could be investigated in Canada to reduce the beetle's impact.
Culicoides (Monoculicoides) grandensis Grogan and Phillips, a new species of biting midge is described and illustrated from Utah and compared with related species.
Five species of gall-inducing Diplolepis are reported from Rosa spp. in Turkey - D. eglanteriae (Hartig), D. fructuum (Rübsaamen), D. mayri (Schlectendal), D. rosae (Linnaeus), and D. spinosissimae (Giraud). The most abundant gall is that induced by D. fructuum which is often considered a pest of the rose industry because it can completely destroy the hips. In some areas, up to 90% of the hips are infested by galls of D. fructuum. Diplolepis eglanteriae, D. mayri, D. spinosissimae, and D. rosae induce galls on the leaves, but are uncommon and not considered pests. The importance of Turkey as a midpoint between Europe and Asia in the distribution of roses and Diplolepis is discussed. The inducer responsible for hip galls in Turkey previously identified as D. mayri is reported here as D. fructuum.
Mesepipsocoides perezgelaberti, n. gen., n. sp., from the Dominican Republic is described and illustrated. It is close to Mesepipsocus Badonnel, but differs from it and from other epipsocid genera in which the females lack v1, in that the pattern of branching of the forewing M is unique, and in that hindwing M is three branched.
Based on a series of laboratory experiments the effects of four rhyparochromids (Heteroptera: Lygaeoidea: Rhyparochromidae) species on seed germination of four species of figs (Moraceae) were tested. Rhyparochromids considerably reduced seed germination depending on the species and the species of fig; it varied from 60 to more than 90%. Seed germination was also affected by agaonids (Hymenoptera: Agaonidae); the proportion of seeds damaged by agaonids varied from 44 to 63%.
The pupal case of Mallophora atra Macquart from South America is described, illustrated, and compared with the South American species M. media Clements and Bennett, M. ruficauda (Wiedemann), and M. sylveirii Macquart, and the North American species M. bomboides (Wiedemann), M. fautrix Osten Sacken, M. leschenaulti Macquart, and M. orcina (Wiedemann).
The genus Tambocerus Zhang and Webb is reported for the first time from China, and four new species from China are described: T. elongatus Shen, T. triangulatus Shen, T. furcellus Shang and Zhang, and T. quadricornis Shang and Zhang. A key to all seven species of the genus is given.
A new genus and species of cucujoid beetle, Pleuroceratos burmiticus Poinar and Kirejtshuk in the Oryzaephilus generic complex of Silvanidae, is described from Early Cretaceous Burmese amber. The new genus is characterized by the head, pronotum and elytra bearing a series of longitudinal costae, large, protruding round eyes, long tri-quadri-dentate mandibles, elongate trochanters, contiguous procoxae, 11- segmented antenna with 3-segmented symmetrical, abrupt, loose club bearing a sensory extension on apical segment, 5 subequal, freely movable, abdominal segments, and elytra covering most of the abdomen. This is the first description of a Mesozoic member of the family Silvanidae.
