Frena and druckknopf: a synopsis of two fore wing-to-body coupling mechanisms in Heteropterodea (Hemiptera)
Authors: Cassis Gerry , Weirauch Christiane 
Published: July 2010

AbstractTwo wing-to-body fastening structures are documented using scanning electron microscopy for 20 exemplar species across the Heteropterodea and 3 species of Auchenorrhyncha. Frenae, holding devices interlocking the costal margin of the fore wing with the margin of the mesoscutellum, occur in representatives of all infraorders of Heteroptera with the exception of Gerromorpha. Frenae were also found in Cicadomorpha and Fulgoromorpha (Auchenorrhyncha), but they are absent in Coleorrhyncha. A knobshaped "druckknopf", covered with tile-like microtrichia on the mesepimeron and interlocking the hind margin of the fore wing with the mesothorax, occurs in Cimicomorpha, Leptopodomorpha and Coreidae (Pentatomomorpha) among Panheteroptera. A ridge or elevation beset with tile-like microtrichia is present in Dipsocoridae and Schizopteridae among Dipsocoromorpha, Nepomorpha and the remaining Pentatomomorpha examined among Panheteroptera, but also in a species of Cicadomorpha and Fulgoromorpha. Scenarios for the evolution of frenae and druckknopf, mapped on a recent hypothesis of higher-level relationships of Heteroptera, are discussed.
Phylogenetic analysis of the American genus Euphoria and related groups based on morphological characters of adults (Coleoptera: Scarabaeidae: Cetoniinae: Cetoniini)
Authors: Philips T. Keith , Orozco Jesús 
Published: July 2010

AbstractThe phylogenetic relationships within the American genus Euphoria Burmeister (Coleoptera: Scarabaeidae: Cetoniinae: Cetoniini) were examined. Fifty-seven adult morphological characters for 40 taxa, including 28 species of Euphoria, representatives of all current and previously recognized genera of Cetoniini from the American continents, and 10 representative genera of Cetoniinae (including five Cetoniini) from the rest of the world were studied. The Cetoniini appear monophyletic and supported by two unique synapomorphies in this study: the flange of the elytra-thorax articulation with a medial process and the posterior legs with a carina or row of setae in the internal angle of the femur. The genus Euphoria is paraphyletic as E. geminata (Chevrolat), appears outside the Cetoniini, a placement possibly due to the effects of convergence. Excluding E. geminata, Euphoria appears as two large monophyletic clades with these as sister to a monophyletic Chlorixanthe Bates. The recognition of Chlorixanthe and Euphoria as the Euphoriina is supported, excluding E. geminata. The recent synonymies of the genera Stephanucha Burmeister and Euphoriopsis Casey with Euphoria are strongly supported by the analysis.
Phylogeny of bethylid wasps (Hymenoptera: Bethylidae) inferred from 28S and 16S rRNA genes
Authors: Carr Martin , Mayhew Peter , Young J. Peter 
Published: July 2010

AbstractWe conduct the first molecular studies of the higher level phylogeny of bethylid wasps (Hymenoptera: Bethylidae). Sequences of the 500-bp D2/D3 expansion regions of the nuclear 28S rRNA gene are obtained for 33 bethylid species in 18 genera covering all four commonly recognized subfamilies, and an additional 13 outgroup species. A 450-bp sequence of the mitochondrial 16S rRNA gene is obtained for a smaller subset of those species. Strong support is found for the monophyly of Bethylidae, and for Bethylinae as the sister to the other bethylid subfamilies. Pristocerinae are supported as monophyletic. A species of Mesitiinae clusters with the Sclerodermini (sensu lato), these two strongly supported as a monophyletic clade. The Epyrini are supported as monophyletic, but our data do not demonstrate whether Pristocerinae or the Mesitiinae+Sclerodermini clade are their closest relatives. Kishino–Hasegawa tests reject the monophyly of the Epyrinae. Our results are consistent with Kieffer's original five major subtaxa of Bethylidae.
Acrolophyses, a new seed bug genus and two new species (Hemiptera: Heteroptera: Rhyparochromidae: Myodochini) from forest-canopy fogging in Ecuador and Peru
Authors: Henry Thomas , Dellapé Pablo 
Published: July 2010

AbstractThe new myodochine (Rhyparochromidae) genus Acrolophyses is described to accommodate the two new species A. arboricolous from Ecuador and Peru, designated as the type species, and A. hadros from Ecuador. The new species are diagnosed and described, and adult photographs, scanning electron photomicrographs of selected structures and illustrations of male genitalia are provided to aid in identification. The relationship of Acrolophyes with the genera Distingphyses and Pephysena is discussed.
Tribelocodia ashei, new genus and new species of Reduviidae (Insecta: Hemiptera), has implications on character evolution in Ectrichodiinae and Tribelocephalinae
Authors: Weirauch Christiane 
Published: July 2010

AbstractA new genus and species of Reduviidae, Tribelocodia ashei gen.n., sp.n, are described from French Guyana. The relationships of Tribelocodia are analyzed within the context of a morphology-based cladistic analysis of Reduviidae. The new genus is placed within the clade Ectrichodiinae+Tribelocephalinae and shows a bizarre combination of characters thought synapomorphic for either Ectrichodiinae or Tribelocephalinae. The analyses support Tribelocodia as the sister taxon to the enigmatic African Xenocaucini within Tribelocephalinae. Tribelocodia ashei, therefore, represents the first Neotropical species of this otherwise Paleotropical group. Implications for character evolution of Ectrichodiinae and Tribelocephalinae are discussed and the diagnosis of Tribelocephalinae is revised. Scanning electron and digital micrographs are provided for Tribelocodia ashei. The holotype of Xenocaucus mancinii China and Usinger, 1949 (Xenocaucini) and a specimen of Ectrichodiella minima (Valdes, 1910), which may represent the sister taxon to the remaining Ectrichodiinae, are illustrated using digital photography.

Authors: Andersen Nils Møller , Polhemus Dan 
Published: July 2010

AbstractRiffle bugs in the genus Rhagovelia have diversified extensively on the island of Madagascar. The current paper defines and segregates a distinct set of species within this endemic assemblage as the diabolica group, containing the previously described species R. diabolica Poisson, R. beangonyi Poisson, and R. milloti Poisson, as well as the following new species described herein: R. compacta and R. suarezensis from northern Madagascar; R. manankazo and R. angulata from central Madagascar; and R. madecassa, R. scupturata and R. origami from eastern Madagascar. Figures of key morphological characters, including male parameres are provided for all species, accompanied by distribution maps.
Biology and Immature Stages of Tetanura pallidiventris, a Parasitoid of Terrestrial Snails (Dipt. Sciomyzidae)
Authors: Knutson L.V. 
Published: July 2010

AbstractTetanura pallidiventris (Fallén) (Dipt. Scionyzidae) lives in terrestrial habitats in northern and central Europe, where the larvae feed on snails of the genera Cochlicopa, Discus, and Retinella. Field and laboratory data on the ecology and behaviour of the species are presented. The egg, third-instar cephalopharyngeal skeleton, and puparium are described and figured. The species is distinguished from T. fallenii Hendel, and the systematic position of the genus Tetanura Fallén is discussed.
The Behaviour of Euphaedra spp. in Relation to Temperature, Relative Humidity and Light (Lep. Rhopalocera)
Authors: Birket-Smith J. 
Published: July 2010

AbstractDifferent types of behaviour of the genus Euphaedra Hbn. has been noticed in its natural habitat, viz. the lowermost strata of the rain forest, and outside this habitat. Observations, which might serve to explain these differences in behaviour, are made on several species of the genus under varying conditions of temperature, relative humidity and sun and shade in an experimental cage.
Contributions to the Knowledge or Swedish Psyllids (Hem. Psylloidea) I-4
Authors: Ossiannilsson Frej 
Published: July 2010

AbstractIn the first contribution a new Psylla species is described, viz. P. betulaenanae, n.sp. On the basis of larval characters this species is stated to be closely related to Psylla betulae (L.), P. alni (L.), P. fusca (Zett.) and the American P. carpinicola (Crawford), these species together constituting Psylla s.str. (type Psylla alni). In the second contribution the larval instars of Psylla foersteri Flor are described and this species is made the type of subgenus Labyrinthopsylla, n.subg. The third contribution deals with our remaining Psylla species which are arranged into three new subgenera, viz. Cacopsylla (type mali (Schmiedb.)), Chamaepsylla (type hartigi Flor), and Hepatopsylla (type nigrita (Zett.)). Also this subdivision is based on larval characters. The fourth contribution is a tentative key to the Swedish Psylla species in the 5th larval instar. No tenable characters for the separation of nigrita (Zett.), elegantula (Zett.), and klapaleki Sulc were discovered, however.
House-dust Mites (Dermatophagoides pteronyssinus (Trt.), D. f arinae Hughes, Euroglyphus maynei (Cooreman) Fain) in Denmark (Acarina)
Authors: Haarløv N. , Alani M. 
Published: July 2010

AbstractFrom houses and flats in Copenhagen inhabited by people allergic or non-allergic to house-dust, 69 samples of dust from mattresses have been collected and investigated for their content of mites and other arthropods. Three species of house-dust mites (Dermatophagoides pteronyssinus (Trt.), D. farinae Hughes, Euroglyphus maynei (Cooreman) Fain) were thus for the first time registered from Denmark besides some other mites and insects. The house-dust mites showed no preference for any of the rooms of the allergic patients nor for those of the controls (Table I). Outside the mattresses house-dust mites were found numerously below cross-bars, on wooden fillets and on floor panels beside the bed. In dust containing no skin scales living mites were not found; with air currents empty skins of mites had been transported around the room (Table 2). The house-dust mites are regarded ecologically to be the best adapted group of indoor mites to stand the low humidities (30-40 % R. H.) of centrally heated houses. Hypothetically it is proposed that the allergens of the house-dust mites are connected with the secretion of the lateral oil glands of hysterosoma.
Biology of Snail-Killing Flies in Sweden (Dipt., Sciomyzidae)1
Authors: Knutson L.V. 
Published: July 2010

AbstractThe major biological features of 53 of the 70 Swedish species of Sciomyzidae (Diptera: Acalyptratae) are summarized. The larvae are found in many kinds of aquatic and terrestrial habitats, and those of most species are air-breathing, overt, polyphagous predators of aquatic and hygrophilous, non-operculate snails. Larvae of a few species are predators or oligophagous, solitary and internal parasitoids of terrestrial snails, Tetanocera elata attacks slugs, and Antichaeta spp. feed in egg-masses of Lymnaeidae and Succineidae. Knutsonia lineata and certain Renocera spp. are the only insects known to feed obligatorily in bivalve Sphaeriidae.

An Aphid Sex Attractant
Authors: Pettersson Jan 
Published: July 2010

AbstractThe experiments described have given the following conclusions: (I) A chemical signal (pheromone) emitted by the oviparous female has an attractive effect upon the males. This signal is not emitted by the virginogeniae. (2) The signal is emitted by organs situated on the hind tibiae of the oviparous female and perceived by organs on the male antennae. (3) The substance is only emitted by the females during a certain period in their lifetime. Apparently, this is principally the condition which has been called active copulatory period (ACP). No emittance was found neither during the passive precopulatory period (PPP) nor during the passive postcopulatory period (PCP). (4) Males are capable of detecting and reacting to the signal already in the last two larval instars. (5) The males do not emit any substance affecting other males. Statistical analysis (Student's t-test) of the material has been excluded as it gave significance only in experiments where differences between the stimuli are apparent.

A Fossil Specimen of the North American Hickory Aphid (Longistigma caryae Harris), Found in Tertiary Deposits in Iceland
Authors: Friedrich Walter L. , Heie Ole E. 
Published: July 2010

AbstractA fossil specimen of Longistigma caryae (Harris) has been found in tuff from Iceland, locality: Hrútagíl i Mókollsdal in northwestern Iceland, age: Upper Miocene or Lower Pliocene. In the present time the species lives exclusively in the region of the Eastern Deciduous Forests of North America on several genera of deciduous trees, a.o. Carya and Fagus. The find certifies paleobotanical evidence indicating that Iceland once belonged in the region of deciduous forests with a flora more like the modern eastern North American flora than any other modern flora region. The recent aphid fauna of Iceland contains only palaearctic, holarctic, cosmopolitic, and endemic species and species common with Greenland and arctic Canada.

Experiments on Growth of Aricia Larvae (Lep. Rhopalocera)
Authors: HØEGH-GULDBERG Ove 
Published: July 2010

AbstractAricia artaxerxes (allous G.-Hb.) ssp. vandalica Kaaber and Høegh-Guldberg flies for such a long period, almost 3 months, that it might be regarded as two generations, just as is the case with the sibling species, A. agestis Schiff. Experiments with simultaneous rearing of the two species, under identical conditions, exhibited a great difference (I) in the rate of growth of the larvae and (2) in the dispersion in time of the larval stage. On examination of previous experiments these findings were confirmed and must be considered as permanent specific differences. The consequence is that eggs of artaxerxes from a single experimental day of oviposition may result in imaginal emergence spread over a long period (3-4 weeks); in nature the dispersion will be so much greater that the long flying time can be explained without assumption of the presence of two broods. The larvae of agestis grow more equally and rapidly, enabling this species to produce 2 (or 3) generations.
The Abdominal Morphology of Povilla adusta Navas (Polymitarcidae) and of Ephemeroptera in General
Authors: Birket-Smith J. 
Published: July 2010

AbstractThe morphology of the abdomen of the mayfly, Povilla adusta Navas (Polymitarcidae) has been studied from dissections of muscles and nerves in male and female imagines and in a female nymph and a number of apparently very primitive traits have been disclosed. The findings have been compared to similar structures in other mayflies and, as a result, a revised interpretation of the genital and postgenital segments of Ephemeroptera is proposed.

C. G. Thomson's Collections of Coleoptera, with a Complete List of Coleoptera Species Described by Him
Authors: Charpentier Reinhold 
Published: July 2010

AbstractIn I967 C. G. Thomson's main collection of Coleoptera was brought back to Sweden from Berlin. It contains about I5,000 specimens of about 3000 species, and it is now preserved at the Zoological Institute of the Lund University, together with Thomson's duplicate collection. Thomson was the author of 329 new names of Coleoptera. 32I of these were described from Sweden or Norway, and for the selection of lectotypes, the original material of 300 of his Scandinavian species is now available in Lund, either in the former Berlin collection or in the duplicate collection. Fourteen original species descriptions were found to have been published earlier or later than generally quoted.
Weight and Life Length of Hibernating Bumble Bee Queens (Hymenoptera: Bombidae) under Controlled Conditions
Authors: Holm Svend Nørgaard 
Published: July 2010

AbstractA large number of bumble bee queens of B. terrestris L. and B. lapidarius L. were hibernated in a refrigerator at 4-5° C. Each queen was placed in a plastic container with Perlite as bedding. Of a total of I079 queens, 75I (7I %) were alive after 8-9 months of hibernation. The queens lost in body weight during hibernation. The weight losses occurred during the first half of the hibernation period after which time the body weight increased. Significant, positive correlations were found between the body weight of the queens and the length of the period of survival during and after hibernation respectively.
Phenology and Microhabitat Selection of Some Flea Beetles (Coleoptera: Chrysomelidae) on Wild and Cultivated Crucifers in Central New York
Authors: Tahvanainen Jorma O. 
Published: July 2010

AbstractThe flea beetle faunae associated with three cruciferous plants, Dentaria diphylla Michx., Barbarea vulgaris R.Br. and Brassica oleracea L. were investigated in the field near Ithaca, N.Y. The flea beetles were sampled regularly from these plants both in their natural habitats and in cultivated plots. The samples were taken either by visually counting the insects or with a D'Vac vacuum net. The behavior and microhabitat preferences of the beetles were determined by making quantitative observations and counting the individuals on vertical layers of the hosts and on host plants growing in different habitats. The flea beetle loads were calculated on the basis of dry weights of plants and flea beetles. Six flea beetle species were found on these three crucifers. On each plant species there was a dominant flea beetle species which constituted over 60 % of the total specimens collected. When the plants were grown in identical cultivated plots in an open field, the relative abundances of flea beetle species attacking them were greatly altered from the situation found in the natural habitats of the hosts. These results, together with the data on the seasonal abundances, behavior and microhabitat selection of the flea beetles, showed that the phenology and habitats of the plants greatly influence their utilization by different flea beetle species and partially determine the distinctiveness of the crucifer-beetle associations.
Infestation Rate of Gamasid Mites on Small Mammals in Northern Sweden
Authors: Edler Anders 
Published: July 2010

AbstractGamasid mites were collected from small mammals in the mountains of northernmost Sweden in autumn, winter/spring and summer. Laelaptidae and Liponyssidae were the most common families. Haemogamasidae comprised a rather small proportion of the material. Greatest infestation was recorded in early spring and in summer, when the number of mites per infested host was also highest. The mammal species were statistically different regarding the infestation and mean value of the mites. Microtus agrestis had most mites. Next came Clethrionomys rufocanus and last C. rutilus and Sorex araneus. Adult M. agrestis were more infested than the younger ones. Generally more males than females were infested. Laelaps clethrionomydis was most abundant on Clethrionomys but Laelaps hilaris and Hyperlaelaps arvalis on Microtus agrestis. Haemogamasus ni di f ormis did not show special preference for any host species. It is more common than Haemogamasus nidi in the present material. In Scandinavia, H. nidiformis becomes relatively more common with increasing latitude.

Precrepuscular Stridulation in Tettigonia viridissima (Orthoptera ensifera)
Authors: Nielsen Erik Tetens 
Published: July 2010

AbstractPrecrepuscular stridulation of Tettigonia viridissima occurs frequently in the field. In the laboratory it may be produced by a combination of high temperature in the light period and so low temperature during darkness that the activity is inhibited. This is explained by assuming that the sensitizing agent is accumulated and the fast sensitization at high temperature thus is able to reach the high threshold of release in light.
