The Trepobatinae (Gerridae) of New Guinea and surrounding regions, with a review of the world fauna. Part 6. Phylogeny, biogeography, world checklist, bibliography and final taxonomic addenda
Authors: Polhemus Dan A. , Polhemus John T. 
Published: July 2010

AbstractThe small waterstriders of the subfamily Trepobatinae have radiated extensively on New Guinea and surrounding archipelagos. The present contribution is the sixth in a series of reports dealing with this endemic fauna, and presents a cladistic analysis at the generic level for the subfamily, a biogeographic analysis, a world checklist, a complete bibliography, and final taxonomic addenda. The taxonomic appendix contains new distributional records for Stygiobates mubi Polhemus & Polhemus, and descriptions of the following new taxa: the new genus Talaudia to hold the previously described Andersenella nilsi Chen & Nieser from the Talaud Archipelago; Metrobatoides bifurcatus sp. n. from northern central Irian Jaya; and Iobates ivimka sp. n. from southern Papua New Guinea. The current cladistic analysis supports the previously proposed tribal classification, with the Metrobatini, Trepobatini, Naboandelini, and Stenobatini all resolved as discrete monophyletic groups. Our cladistic and biogeographic analyses also suggest that the current distribution of trepobatine genera in the New Guinea region has been strongly influenced by past tectonic events, most notably the accretion of island arc terranes derived from the Solomons and Halmahera arc systems. This has led to distinct areas of freshwater and marine endemism among the Metrobatini and Stenobatini in the areas surrounding Halmahera, the Vogelkop Peninsula, and northeastern New Guinea plus nearby islands. By contrast, the distribution of Naboandelini in the New Guinea region suggests a vicariance pattern with Australia across the Torres Strait.
Distribution patterns and taxonomy of some legume-feeding psyllids (Hemiptera: Psylloidea) and their hosts from the Iberian Peninsula, Morocco and Macaronesia
Authors: Percy Diana M. 
Published: July 2010

AbstractDistribution patterns between continental and continental-island sister taxa are compared for some legume-feeding psyllids (Arytaininae, Psylloidea) and their host plants (Genisteae, Leguminosae). The host plant genera Adenocarpus, Chamaecytisus, Retama and Teline are characterized by distribution disjunctions, which sometimes match the disjunctions in the associated psyllids. Sister taxa pairs of Retama- and Teline-feeding psyllids from the continent and Macaronesian islands exhibit a similar geographic disjunction as their host plants, but this pattern is not found in Adenocarpus- or Chamaecytisus-feeding psyllids and their hosts. In addition, three closely related continental psyllids reflect the distribution of their Adenocarpus hosts in the montane regions of Morocco and Andalusia, but are not related to other Adenocarpus-feeding species. These examples suggest that among the Genisteae-feeding psyllids, shared distribution patterns with their hosts are localized rather than characteristic of the group as a whole. Six new species of psyllid, which feed on legume shrubs in the Genisteae, and are endemic to the Iberian Peninsula and Morocco, are described and illustrated. These species are in two taxonomically complex arytainine genera, Arytainilla and Livilla. Immature stages provide additional morphological characters useful for resolving taxonomic relationships within the Arytaininae, and the 5th instar nymphs of several species are described and illustrated. Genistoid-feeding psyllids are not known from all genera in the Genisteae but this may be due to incomplete sampling of rarer genistoid legumes. The majority of psyllids newly described here are narrow range endemics in either Andalusia or Morocco; one species occurs in both Andalusia and Morocco, and one species is more widespread in the Iberian Peninsula.
Revision of the Neotropical genus Syntomoneurum Becker (Diptera: Dolichopodidae)
Authors: Wheeler Terry A. , Brooks Scott E. 
Published: July 2010

AbstractThe Neotropical genus Syntomoneurum Becker is revised. The genus is defined within the subfamily Dolichopodinae on the basis of the possession of a strong basiventral seta on the fore femur, a single notopleural seta, and very reduced pulvilli on the midleg and hindleg in both sexes. Males also possess a cluster of 2-3 strong setae on both the fore femur and mid coxa. One new species, Syntomoneurum giganteum Brooks is described and the three previously known species (S. alatum Becker, S. anale Parent, S. beckeri Parent) are redescribed. A lectotype is designated for S. alatum. A key to the species is provided. Evidence supporting the placement of Syntomoneurum in the subfamily Dolichopodinae near Tachytrechus Haliday is discussed.
A cladistic analysis of Diopsidae (Diptera) based on morphological and DNA sequence data
Authors: Baker Richard , Meier Rudolf 
Published: July 2010

AbstractThe results of a cladistic analysis based on a combined character matrix consisting of the morphological data set of Meier & Hilger (2000) and the molecular data set of Baker & al. (2001) is presented. The data set is subjected to an extensive sensitivity analysis and equal character weighting is found to perform best according to character incongruence and tree support. The sensitivity analysis also reveals a remarkable stability of the preferred tree with 25 of the 36 tree nodes supported under 16 different analysis conditions. Cyrtodiopsis is synonymized with Teleopsis and Shillito's (1971) synonymization of Trichodiopsis and Chaetodiopsis with Diasemopsis is confirmed. Morphological and DNA sequence data agree on all major clades and conflict is restricted to the placement of two species within their respective genera. Only in one case can the conflict be confidently resolved. Partitioned Bremer Support values reveal that 90% of the tree support is generated by the DNA sequence characters, although the average morphological character contributes twice the support of an average molecular character. The evolution of eye-stalk morphology and of a meiotic drive chromosome system in Teleopsis is briefly discussed in the light of the phylogenetic tree.
Review of the North American Heteraphorura Bagnall, 1948 (Collembola: Onychiuridae) with description of two new species
Authors: Pomorski Romuald J. 
Published: July 2010

AbstractA new supplemented diagnosis of Heteraphorura Bagnall, 1948 is provided. The genus Japonychiurus Yosii, 1996 is a junior synonym of Heteraphorura. Two new species are described: H. justynae sp. n. and H. intricata sp. n. H. subtenuis (Folsom, 1917), H. tala (Christiansen & Bellinger, 1980), H. bima (Christiansen & Bellinger, 1980), H. cassa (Christiansen & Bellinger, 1980) are redescribed on the basis of types and new materials. An identification key to the North American members of the genus is given.
A revision of the shore-fly genus Philotelma Becker (Diptera: Ephydridae)
Authors: Kubátová-Hiršová Hana , Mathis Wayne , Zatwarnicki Taduesz 
Published: July 2010

AbstractAll known shore-fly species (5) of the genus Philotelma Becker are revised, including P. tecopa, new species (California. Inyo: Tecopa Hot Spring (36°52.7'N, 116°13.9'W)). Philotelma is only known from the Northern Hemisphere, and the included species are generally more widespread than previously known. With discovery that some species are more widespread and correction of the identification of others, the following new synonymies are proposed: P. alaskense Cresson = P. defectum (Haliday) and P. strandi Duda and P. tamarani Zatwarnicki & Báez = P. parvum (Kramer). The Afrotropical species, Philotelma mirabilis Canzoneri & Meneghini, is transferred to the genus Lamproscatella Hendel (new combination). A lectotype is designated for Ephydra defecta Haliday. For perspective and to facilitate identification, a key to the genera of Scatellini is provided. All species are illustrated and distribution maps are also provided.
The tusked king cricket, Libanasidus vittatus (Kirby, 1899) (Anostostomatidae), from South Africa: morphological and molecular evidence suggest two cryptic species
Authors: Chimimba Christian , Bateman Philip , Bastos Armanda , Brettschneider Helene , Scholtz Clarke 
Published: July 2010

AbstractAn evaluation of genetic structuring and morphometric variation within tusked king crickets, Libanasidus vittatus (Kirby, 1899), from South Africa suggests two main population assemblages. Maximum likelihood (ML), Parsimony, Bayesian and phenetic analyses of mitochondrial cytochrome oxidase I (COI) sequence data recovered two well-supported clades corresponding to two biogeographically distinct populations. Canonical variates (discriminant) analysis (CVA) also showed evidence of two phenetic assemblages that correspond to the genetically delineated groups. Libanasidus vittatus is the recognized species occurring within an eastern population in South Africa (Mpumalanga and Eastern Cape Provinces), while a possible novel species occurs within a north–western population in South Africa (Limpopo and Gauteng Provinces). Using a molecular clock estimate of 2.0% divergence per million years, suggests isolation of the two populations at approx. 1.65 million years ago, possibly due to the formation of isolating forest pockets during the dry Pleistocene Epoch. The average genetic divergence of 3.3% between the two populations, and low migration rate estimates corresponding to less than one female migration per generation further support the presence of two cryptic tusked king cricket species in South Africa.
Phylogenetic analysis of Hydrophiloidea (Coleoptera: Polyphaga) based on molecular data and morphological characters of adults and immature stages
Authors: Bernhard Detlef , Beutel Rolf , Komarek Albrecht , Ribera Ignacio 
Published: July 2010

AbstractAn extensive combined data set comprising 160 morphological characters of adults and immature stages of Hydrophiloidea and sequences of six different genes were analysed using parsimony and a Bayesian approach. Analyses were carried out with equal weight for individual morphological and molecular characters, and alternatively with approximately equivalent weight for the entire partitions, i.e., 147 informative morphological characters × 9.5 ≈ 1383 informative molecular characters. With the former approach some conventional groups such as the histeroid lineage (Histeridae and Sphaeritidae), Helophorinae and Sphaeridiinae were recovered. However, the branching pattern as a whole is strongly in contrast to the results of previous studies. The results obtained with the modified weighting scheme (9.5:1) conform more to morphology based analyses. The monophyly of Hydrophiloidea, Histeridae + Sphaeritidae, Epimetopinae + Georissinae, Helophorinae, Sphaeridiinae and of the hydrophiline-sphaeridiine lineage is supported in the parsimony analysis. Spercheinae is placed as sister group of all the remaining hydrophiloid groups and a clade is formed by the subfamilies Epimetopinae, Georissinae, Hydrochinae and Helophorinae. In the Bayesian analysis the monophyly of Hydrophilidae is supported. Georissinae form a clade with Hydrochinae, and Epimetopinae are placed as sister group of a clade comprising Spercheinae + the hydrophiline-sphaeridiine lineage. Berosus is placed as the sister group of the remaining groups of Hydrophilinae-Sphaeridiinae in both analyses, and Sphaeridiinae are always nested within a paraphyletic Hydrophilinae. The divergent results of the different analyses show that important questions in the phylogeny of Hydrophiloidea such as for instance the placement of Spercheinae are still open.

The Atomaria Species (Col. Cryptophagidae) of Madeira and the Canary Islands Including Data on the Wollaston Collections and Lectotype Designations for His Species
Authors: Johnson Colin 
Published: July 2010

AbstractOf the twelve species of the genus Atomaria known from Madeira and/or the Canary Islands, six are endemics, and are apterous. They have no doubt evolved in situ. The eight species (excluding a replacement name) described by Wollaston are represented in the British Museum, one (pilosula) by the holotype, the remainder by lectotypes designated by the writer. Five of Wollaston's names are valid. A timetable of facts relating to Wollaston's researches and collections is presented.

Published: July 2010

AbstractIn Norway 59 species of Olethreutini have been found. Four of these are for the first time recorded as new to the country, viz. Eudemis porphyrana (Hb.), Apotomis fraterculana Krog., A. algidana Krog. and Argyroploce tiedemanniana (Z.). One species, Olethreutes umbrosana (Frr.), is deleted from the Norwegian list. A special attention is paid to Apotomis Hb. and Endothenia Steph. which comprise several confused species.
Cuticular Morphology of the Scent Gland Areas of Some Heteropterans
Authors: Johansson Arne Semb , Braten Trond 
Published: July 2010

AbstractThe cuticle of the evaporative area of the metathoracic scent glands of adult heteropterans shows marked structural modifications. One specialized type of cuticle is covered by micro-flakes supported and interconnected by low ridges. In Lygaeidae and Pyrrhocoridae this cuticle is found along the borders of the evaporative areas, whereas in the Pentatomidae it covers most of this area. The structure and distribution of this specialized cuticle is supposedly connected with the spreading of the volatile scent fluid.
The Sphaerophoria Species Described by J. W. Zetterstedt (Dipt., Syrphidae)
Authors: Andersson Hugo 
Published: July 2010

AbstractThe type series of the Sphaerophoria species described by J. W. Zetterstedt have been examined and lectotypes designated. It has been confirmed that S. nigricoxa Zett. is a synonym of S. scripta L. and that S. flavicauda Zett. and S. nitidicollis Zett. are synonyms of S. rueppelli Wied. S. loewi Zett., S. dubia Zett., and S. abbreviata Zett. are good species. The descriptions of S. multipunctata Zett. and S. insignita Zett. are based on single abnormal females. With our present knowledge of Sphaerophoria females, they cannot be interpreted. S. sarmatica Bankowska is a synonym of S. dubia Zett. (n. syn.).

Authors: Israelson Gunnar 
Published: July 2010

AbstractThe taxonomic status of the two often confused species, Aderus pentatomus (Thoms.) and A. breyicornis (Perris) is examined and the species are redescribed on a rather rich material. The most reliable structures are found in the head and its appendages, in the abdominal sternites, the hind egs, and the male genitalia. Information is given on geographical distribution as well as on life history.
Effect of Light Intensity and Air Humidity on Flight Initiation in Blastophagus piniperda L. (Col. Scolytidae)
Authors: Perttunen Vilho , Häyrinen Tuula 
Published: July 2010

AbstractThe spontaneous take-off activity of Blastophagus piniperda was investigated at light intensities of 0.I, I, I0, I00, and I000 lux at a constant temperature of 25°C. and at an air humidity of 77 % R.H. The effect of air humidity (o %, 77 %, and (00 % R.H.) on the take-off rate was studied in spring specimens only. At the low light intensities of 0.I and I lux the cake-off rates were clearly lower than at the higher light intensities of I00 and I000 lux. At all light intensities there were marked seasonal differences in the take-off rate. At each light ntensity the rate was clearly higher in the specimens of the new generation in July than in the spring specimens. At the high light intensities of I00 and I000 lux, and at I0 lux in July, the high rate of take-off activity remained relatively constant throughout the I5-minute experimental period. At the low light intensities the take-off rate was very low in the early part of the experiment, but with time the rate increased considerably. Thus the initial inhibitory effect of very low light intensity is rapidly abolished, probably by adaptation. In the beginning of the I5-minute experiments the take-off rate is high at the air humidity of I00 % R.H., low in the dry air of nearly o % R.H., and intermediate at 77 % R.H. After the first 3-minute period these differences are largely abolished.
The Chilopoda and Diplopoda of Iceland
Authors: Eason E.H. 
Published: July 2010

AbstractFive species of myriapods have previously been recorded from Iceland. To these are here added: Brachygeophilus truncorum (Bergsö & Meinert), Brachydesmus superus Latzel and Polydesmus coriaceus Porst. A further dubious diplopod from Skaftafell is commented upon. The variability and the life history within the Icelandic populations of Lithobius and Lamyctes species are described. The history of the Icelandic myriapod fauna is discussed. It is concluded that most species probably arrived by human transport. Only three species (Lithobius melanops, Lamyctes fulvicornis, Proteroiulus fuscus) may be older on the island.

Authors: Müller Karl 
Published: July 2010

AbstractThe locomotor activity of the larvae of Diura nanseni appearing in the drift is not synchronized on the 24h period under midsummer. A synchronization will not begin until the minimum light of the night is less than I50 Lux. The larvae are night active until emergence in April-May the following year. Their locomotor activity follows the basic pattern of locomotor activity observed also in water insects in middle Europe.
A Revision of the Scandinavian Tachydromiinae (Dipt., Empididae) described by J. W. Zetterstedt
Authors: Chvála Milan 
Published: July 2010

AbstractJ. W. Zetterstedt described between I8I9-I850 thirty-seven species of the Empidid subfamily Tachydromiinae in combination with Tachydromia Meig. (30), Tachypeza Meig. (5), Drapetis Meig. (I) and Empis L. (I). A revision of these species has been based on a study of Zetterstedt's Collection at Lund, Sweden. Lectotypes or holotypes for thirty-six of Zetterstedt's species are designated and a further two lectotypes for Platypalpus pallipes (Fall., I8I5) and Platypalpus boreoalpinus Frey, I943 have been selected. Five species are redescribed, viz., Platypalpus brevicornis (Zett., I842)—the male sex is described for the first time—, Crossopalpus curvinervis (Zett., I842), comb.nov., Platypalpus sordidus (Zett., I838), Platypalpus unguiculaws (Zett., I838) and Platypalpus boreoalpinus Frey, I943. The following species are described as new: Platypal pus confiformis sp.n., Platypalpus zetterstedti sp.n., and Platypalpus alpinus sp.n. Some new synonymy is established: Symballophthalmus scapularis Collin, I96I is a synonym of Symballophthalmus fuscitarsis (Zett., I859), Tachydromia gilvipes Coquillett, I900 and Platypalpus xanthopodus Melander, I928 are synonyms of Platypalpus unguiculatus (Zett., I838), Platypalpus extricatus (Collin, I96I) is a synonym of Platypalpus Iongiseta (Zett., I842), Drapetis nigripes Zett., I859 is a synonym of Drapetis pusilla Loew, I859, Tachydromia parvicornis Zett., I859 is a synonym of Crossopalpus nigritellus (Zett., I842). A new name Platypalpus anomalinervis nom.nov. is proposed for Tachydromia curvinervis Collin, I94I (nec Zett., I842), described from Ussuri. Platypalpus candicans (Fall.) is still known only from the female sex, the recorded males are represented in Zetterstedt's Collection by males of Platypalpus longiseta (Zett.) (syn. extricatus Coll.) and Platypalpus stabilis (Coll.). Also Lundbeck (I9I0) described the male sex of P. candicans (Fall.) and P. major (Zett.) by mistake.
Disappearance as a Protective Factor
Authors: Lindroth Carl H. 
Published: July 2010

AbstractCertain species of genus Lebia (Carabidae) are strikingly similar in color to species of flea-beetles (Alticinae, Chrysomelidae) with which they are regularly associated on the foodplants of the latter. A host-parasite relationship is suggested. Other chrysomelids, known as hosts of a Lebia, are not imitated. It is proposed that the jumping habit of the flea-beetles is an effective protection against certain birds and that they are imitated by the accompanying Lebia for this reason. The situation is interpreted as a case of Bates'ian mimicry. A similar case is the striking resemblance between two species of the African genus Lebistina and their respective host, flea-beetles of the genus Diamphidia. These are used by the bushmen for the production of arrow-poison. It is therefore assumed that here the protection is of a chemical nature.
