RESUMO

Japanese species of the genus Eloeophila are revised. Five new species, E. apicisetula sp. nov., E. canidorsalis sp. nov., E. enischnophallus sp. nov., E. hadrophallus sp. nov., and E. tergilobellus sp. nov. are described. One subspecies and two species are synonymized, E. subaprilina yezoensis (Alexander, 1924) with the nominotypical subspecies, E. hidana (Alexander, 1970) with E. persalsa (Alexander, 1940), and E. mishimai (Alexander, 1969) with E. kintaro (Alexander, 1957). Images of the habitus and wings, and drawings of the male terminalia of the Japanese species are shown. Distributions and a key to the Japanese species are provided.

RESUMO

Phyllolabis eiroae sp. nov. and P. martinhalli sp. nov. are described from the centre of the Iberian Peninsula. These two remarkable species were collected using carrion-baited traps, running during winter, in several localities of Madrid province (Spain). The two new species are well differentiated from the other Phyllolabis Osten Sacken species recorded from the Iberian Peninsula, P. savtshenkoi Theowald, and those from the west Palaearctic. An identification key to differentiate the three Phyllolabis species occurring in the Iberian Peninsula is provided. The first images of P. savtshenkoi, based on the holotype and a male specimen recorded from a cave located in Ja (Spain), are also provided.

RESUMO

A key to larvae of Ptychopteridae (phantom crane flies) is provided for species inhabiting Northern Europe. The key encompasses seven species, including the previously undescribed larvae of Ptychoptera longicauda (Tonnoir 1919). Larval specimens examined were primarily sampled from sites in Denmark. Larvae were associated with correctly identified adults based on DNA barcode (COI) sequence. In the development of the key, a wide suite of morphological characteristics were examined and evaluated for their utility to separate species. Current distribution maps are provided for all species occurring within Northern Europe. Based on records of larvae from Denmark and Finland, notes on larval habitats are given. We also present flight periods for all species examined during this study. Finally, the status of the enigmatic species Ptychoptera obscura (Peus 1958) is briefly discussed.

RESUMO

Suction is widely used by animals for strong controllable underwater adhesion but is less well understood than adhesion of terrestrial climbing animals. Here we investigate the attachment of aquatic insect larvae (Blephariceridae), which cling to rocks in torrential streams using the only known muscle-actuated suction organs in insects. We measured their attachment forces on well-defined rough substrates and found that their adhesion was less reduced by micro-roughness than that of terrestrial climbing insects. In vivo visualisation of the suction organs in contact with microstructured substrates revealed that they can mould around large asperities to form a seal. We have shown that the ventral surface of the suction disc is covered by dense arrays of microtrichia, which are stiff spine-like cuticular structures that only make tip contact. Our results demonstrate the impressive performance and versatility of blepharicerid suction organs and highlight their potential as a study system to explore biological suction mechanisms.

RESUMO

In most organisms, various physiological and behavioral functions are expressed rhythmically. Previous studies have shown that thermoperiod is an important factor affecting circadian clock-related genes that regulate insect locomotor activity. Bradysia odoriphaga Yang & Zhang is an underground pest that attacks more than 30 crops but is especially damaging to Chinese chives. In this study, we analyzed the adult eclosion time and period (Boper) gene expression in B. odoriphaga as affected by temperature (cycling vs constant temperature), insect stage, and tissue specific. We found that the eclosion time and expression of the Boper gene changed during the temperature cycle but not under a constant temperature. Silencing of Boper expression significantly decreased the adult eclosion rate and significantly increased adult mortality and malformation. The findings indicate that thermoperiod alters Boper expression and regulates the eclosion rhythm.

RESUMO

Two new species of Leptomorphus Curtis, L. guatemalensis sp. n. and L. juxtafurcatus sp. n., are described from Guatemala, figured, and compared with congeners. The new species belong to the clade including the "furcatus" and "walkeri" species-groups as defined by Borkent Wheeler (2012). L. guatemalensis sp. n. can be recognized by the gonocoxite bulbous and crescent-shaped with the apex asetose and spatula-like, but remains without a clear sister-species. Based on the structure of the male terminalia, particularly the presence of submedian, pointed lobes on sternite nine, L. juxtafurcatus sp. n. is suggested to be the sister-species to L. furcatus Borkent from the southwestern USA and northern Mexico; these species can be distinguished by the form of the gonocoxites.

RESUMO

The systematics of the dipteran family Sciaridae is based mainly on morphological characters and has remained quite controversial. In this study, we used two mitochondrial DNA markers (CO1, 16S) and a nuclear one (28S) to take a glimpse into phylogenetic relationships of part of the North and Central European Sciaridae. A total of 91 species from 19 genera were analysed using Maximum Likelihood based phylogenetics (depending on the availability of valid sequences, 50-70 per gene). We strengthen the suggestion of the Chaetosciara group as an independent subfamily. Within the subfamily Megalosphyinae, two separate Bradysia clades were identified, suggesting a close relation between the genera Zygoneura, Austrosciara, and Scatopsciara. The genus Alpinosciara gen. n. is established to place the species of the former Corynoptera crassistylata group inside the subfamily Megalosphyinae. This new genus now includes 22 species.

RESUMO

We revise the available material of fossil Bibionidae from the Oligocene of Germany, except for the Early Oligocene site of Kleinkems which has recently been revised. The bulk of the material originates from the Late Oligocene Lagerstätten of Rott and Enspel. One new species, Bibio castaneipennis sp.n., is described from Enspel. The following new combinations are established: Hesperinus heeri (Heyden Heyden, 1865) comb.n. (previously Plecia heeri), Plecia dubia (Germar, 1837) (previously Phthiria dubia). Plecia collossea (Heyden Heyden, 1865) is removed from synonymy with Plecia morio (Heer, 1849), Plecia gracilenta (Heyden Heyden, 1865) is removed from synonymy with Plecia lygaeoides (Heer, 1849). The following new synonymies are established: Plecia elegantula Meunier, 1915 = Penthetria rottensis Statz, 1943 = Penthetria scita Statz, 1943 = Hesperinus heeri (Heyden Heyden, 1865); Plecia superba Meunier, 1915 = Plecia imperialis Statz, 1943 = Plecia philippi Statz, 1943 = Plecia collossea (Heyden Heyden, 1865); Helophilus primarius Germar, 1837 = Plecia abava (Heyden Heyden, 1865) = Plecia satyrus Statz, 1943 = Plecia dubia (Germar, 1837); Plecia expositia (Heyden Heyden, 1865) = Plecia grandaeva (Heyden Heyden, 1865) = Plecia antenata (Heyden Heyden, 1865) = Plecia elongata (Heyden Heyden, 1865) = Plecia pulchella Meunier, 1915 = Plecia hypogaea (Heyden Heyden, 1865); Plecia schineri (Heyden Heyden, 1865) = Plecia macrocephala (Heyden Heyden, 1865); Plecia lapidaria (Heyden Heyden, 1865) = Bibio brachypteroides Meunier, 1915 = Plecia vulpina Statz, 1943 = Plecia pinguis (Heyden Heyden, 1865); Plecia lapidaria nigra Statz, 1943 = Plecia sluiteri Meunier, 1917; Plecia veterana (Heyden Heyden, 1865) = Plecia stygia (Heyden Heyden, 1865); Bibio spadicea Statz, 1943 = Bibio aerosus Statz, 1943; Bibio heydeni Meunier, 1920 = Bibio comosella Statz, 1943 = Bibio germari Meunier, 1920; Plecia heroica Heyden Heyden, 1865 = Bibio giganteus Unger, 1841; Bibio infumatus Meunier, 1915 = Bibio mimas L. Heyden, 1870. The following names are placed as nomina dubia pending rediscovery of the type material: Plecia volgeri (C.H.G. Heyden, 1859); Bibio janus L. Heyden, 1870; Bibio tertiarius C.H.G. Heyden, 1862; Dilophus deletus (C.H.G. Heyden, 1862). The male morphotypes described but not formally named by Statz (1943) are tentatively assigned to named species.

RESUMO

Ametrodiplosis Rübsaamen (Diptera: Cecidomyiidae: Clinodiplosini) is a mostly Holarctic gall midge genus whose species are associated with a wide range of seed plant families, either as gall-inducers or inquilines. In this study, we describe three species of Ametrodiplosis from Japan: A. adetos n. sp. feeding in the flowers of Tylophora aristolochioides Miq. (Apocynaceae); A. aeroradicis n. sp. inducing aerial root galls on Trachelospermum asiaticum (Sieb. et Zucc.) Nakai and T. gracilipes var. liukiuense (Apocynaceae); and A. stellariae n. sp. forming leaf bud galls on Stellaria uliginosa Murray var. undulata (Thunb.) Ohwi (Caryophyllaceae). A molecular phylogenetic analysis using mitochondrial COI and ribosomal 16S genes and nuclear ribosomal 28S gene were conducted for the three new Ametrodiplisis species and other clinodiplosine taxa sequences available in GenBank. The analysis supported the monophyly of Ametrodiplosis despite the variable life history of the three species. In addition, it indicated very low intraspecific genetic divergence among the individuals from different localities and/or host plants. A taxonomic key to the three new Japanese species of Ametrodiplosis is provided.

RESUMO

BACKGROUND: Pheromone-mediated mating disruption, which uses large amounts of synthetic female pheromones to interrupt insect reproductive behavior, has been successful for managing important agricultural pests. While multiple mechanisms have been discovered explaining how synthetic pheromone treatments prevent males from finding females, it is less clear how unnaturally large doses of synthetic sex pheromone impact the behavior of female insects, particularly nonlepidopteran females. In some species, 'autodetecting' females possess pheromone receptors and respond to ambient pheromones by altering their mating behavior. Here, we test whether exposure to stereospecific and racemic synthetic pheromones influences calling and subsequent propensity to mate in female swede midge (Contarinia nasturtii Kieffer; Diptera: Cecidomyiidae), a pest of Brassica crops. RESULTS: In both laboratory and field settings, females exposed to stereospecific and racemic three-component pheromone blends called significantly more frequently and for longer durations than midges in control treatments. In the field, midges were twice as likely to call in pheromone-treated plots versus nontreated plots. Additionally, pheromone pre-exposure reduced subsequent mating: while 68% of female midges mated following control conditions, only 42% and 35% of females pre-exposed to stereospecific and racemic three-component blends mated, respectively. CONCLUSION: While more frequent calling within pheromone-treated backgrounds may increase the likelihood that females are detected by males, a reduction in female propensity to mate would increase the efficacy of a pheromone-mediated mating disruption system. Our work presents the first known investigation of autodetection behavior in Cecidomyiidae. Additional research is necessary to understand the implications of female autodetection for swede midge management.

RESUMO

A fully annotated catalog of genus- and species-group names of Neotropical Lauxaniidae (Diptera: Lauxanioidea) is presented, providing details of references to these names in literature, and providing additional details such as distributions, generic combinations, synonymies, misspellings and emendations, information on types, notes on unusual situations, etc. As this catalog is meant to supplement the older Catalog of the Diptera of America North of Mexico, to complete the cataloging of the New World Lauxaniidae, "Neotropical" is herein inclusive of everything south of the United States, and the Nearctic parts of Mexico are not separately distinguished. The catalog is organized alphabetically within each of the three lauxaniid subfamilies, Eurychoromyiinae, Homoneurinae and Lauxaniinae, treating 91 available genus-group names, of which 77 represent valid genera. In the species-group, the catalog treats 441 available species-group names, of which 391 represent valid Neotropical lauxaniid species, 39 are invalid, three are valid but extralimital lauxaniids, five are valid but removed from Lauxaniidae, and two are new replacement names for two homonyms outside Lauxaniidae. The following nine new genera are described, based on previously described species: Elipolambda Gaimari Silva (type species, Sapromyza lopesi Shewell, 1989), Griphoneuromima Silva Gaimari (type species, Sapromyza frontalis Macquart, 1844b), Meraina Silva Gaimari (type species, Lauxania ferdinandi Frey, 1919), Myzaprosa Gaimari Silva (type species, Myzaprosa mallochi Gaimari Silva), Paradeceia Silva Gaimari (type species, Sapromyza sororia Williston, 1896b), Pseudodeceia Silva Gaimari (type species, Lauxania leptoptera Frey, 1919), Sericominettia Gaimari Silva (type species, Minettia argentiventris Malloch, 1928), Zamyprosa Gaimari Silva (type species, Sapromyza semiatra Malloch, 1933), and Zargopsinettia Gaimari Silva (type species, Minettia verticalis Malloch, 1928). The following four new replacement names in the species-group replace junior homonyms: Myzaprosa mallochi Gaimari Silva (for Sapromyza spinigera Malloch, 1933, nec Malloch, 1925), Pseudogriphoneura mallochi Silva Gaimari (for Minettia infuscata Malloch, 1928, nec Sciomyza infuscata Wulp, 1897), Xenochaetina hendeli Silva Gaimari (for Allogriphoneura robusta Hendel, 1936, nec Helomyza robusta Walker, 1858), Zamyprosa macquarti Gaimari Silva (for Sciomyza nigripes Blanchard, 1854, nec Sapromyza nigripes Macquart, 1844). The following six genus-group names are new synonyms: Allogriphoneura Hendel, 1925 (= Xenochaetina Malloch, 1923), Bacilloflagellomera Papp Silva, 1995 (= Stenolauxania Malloch, 1926), Haakonia Curran, 1942 (= Xenochaetina Malloch, 1923), Homoeominettia Broadhead, 1989 (= Allominettia Hendel, 1925), Paraphysoclypeus Papp Silva, 1995 (= Physoclypeus Hendel, 1907), Tibiominettia Hendel, 1936 (= Allominettia Hendel, 1925).

RESUMO

The movement behavior of the pine needle gall midge (Thecodiplosis japonensis Uchida Et Inouye (Diptera: Cecidomyiidae)), an invasive species in China, was determined by using a tethered flight technique and digital videography in the laboratory. The flight distance, duration, and speed of females were compared at different ages (2-10 h) and ambient temperatures (17, 21, 26, and 30°C). Female flight distance and duration at 26°C were significantly greater than those at 17°C and 21°C. The age of T. japonensis did not significantly affect the three flight characteristics. For females at 2-10 h of age at 26°C and 70% RH, the maximum flight distance was 667.59 m; the longest flight time was 6,222.34 s; and the fastest flight speed was 0.44 m·s-1. For larvae wetted with water, the highest jump was 5.7 cm; the longest jump was 9.6 cm; and the greatest distance moved in 5 min was 27.13 cm, which showed that the active dispersal potential of larvae was very low.

RESUMO

Stenophragma borneense sp. n. from Borneo is described and illustrated. In the new species, a variability in the presence/absence and location of R4+5, including between left and right wings of the same specimen, is observed. The cell between Rs and R4+5, if present, can be triangular, trapeziform or almost squared. An identification key to the extant species of the genus is also provided.
