  • A Faunal Survey of the Elateroidea of Montana by Catherine Elaine
    A faunal survey of the elateroidea of Montana by Catherine Elaine Seibert A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology Montana State University © Copyright by Catherine Elaine Seibert (1993) Abstract: The beetle family Elateridae is a large and taxonomically difficult group of insects that includes many economically important species of cultivated crops. Elaterid larvae, or wireworms, have a history of damaging small grains in Montana. Although chemical seed treatments have controlled wireworm damage since the early 1950's, it is- highly probable that their availability will become limited, if not completely unavailable, in the near future. In that event, information about Montana's elaterid fauna, particularity which species are present and where, will be necessary for renewed research efforts directed at wireworm management. A faunal survey of the superfamily Elateroidea, including the Elateridae and three closely related families, was undertaken to determine the species composition and distribution in Montana. Because elateroid larvae are difficult to collect and identify, the survey concentrated exclusively on adult beetles. This effort involved both the collection of Montana elateroids from the field and extensive borrowing of the same from museum sources. Results from the survey identified one artematopid, 152 elaterid, six throscid, and seven eucnemid species from Montana. County distributions for each species were mapped. In addition, dichotomous keys, and taxonomic and biological information, were compiled for various taxa. Species of potential economic importance were also noted, along with their host plants. Although the knowledge of the superfamily' has been improved significantly, it is not complete.

ZooKeys 441: 291–303. doi: 10.3897/zookeys.441.7586 Abstract A checklist of the Agromyzidae (Diptera) recorded from Finland is presented. 279 (or 280) species are currently known from the country. Phytomyza linguae Lundqvist, 1947 is recorded as new to Finland. Keywords Checklist, Finland, Diptera, biodiversity, faunistics Introduction The Agromyzidae are called the leaf-miner or leaf-mining flies and not without reason, although a substantial fraction of the species feed as larvae on other parts of living plants. While Agromyzidae is traditionally placed in the superfamily Opomyzoidea, its exact relationships with other acalyptrate Diptera are poorly understood (see for example Winkler et al. 2010). Two subfamilies are recognised within the leaf-mining flies: Agromyzinae and Phytomyzinae. Both are now recognised as natural groups (Dempewolf 2005, Scheffer et al. 2007). Unfortunately the genera are not as well defined: at least Ophiomyia, Phy- toliriomyza and Aulagromyza are paraphyletic in DNA sequence analyses (see Scheffer et al.

  • Diptera; Diadocidiidae and Mycetophilidae)
    Fungus gnats from Jostedalen, West Norway (Diptera; Diadocidiidae and Mycetophilidae) GEIR E. E. SBLI Snli, G. E. E. 1994. Fungus gnats from Jostedalen, West Norway (Diptera: Diadocidi- idae and Mycetophilidae). Fauna norv. Ser. B 41: 1-12. During a study of terrestrial invertebrates in Jostedalen in 1988, more than 3.000 specimens of fungus gnats were caught. 214 species were recognized, belonging to the families Diadocidiidae and Mycetophilidae. The number of species in Jostedalen is exceptionally high when compared to number of species recorded from other local areas in Europe. The genus Drepanocercus (Vockeroth, 1980) is recorded for the first time from the Palaearctic region. Other rare species are Mycomya simulans Vaisanen, 1984, Acnemia falcata Zaitzev, 1982, Zygom.via pseudohumeralis Caspers, 1980, Anatella aquila Zaitsev, 1989. A. fungina Plassmann, 1984, Exechia subfrigida Las- tovka & Matila, 1974. Exechiopsis dryaspagensis Chandler. 1977 and E. pseudopul- chella (Lundstrom, 1909). Twenty species could not be identified, half of which undoubtly represent undescribed species. The fauna of Norwegian fungus gnats is poorly documented, and most species recorded here are new to Norway. According to the present knowledge on the distribution of fungus gnats, the fauna in Jostedalen seems to have an affinity to the central/eastern Palaearctic fauna, and has more species in common with the Finnish fauna than with the British. Geir E. E. Snli, Museum of Zoology, University of Bergen, Musiplass 3, N-5007 Bergen, Norway. INTRODUCTION The river Jostedola has its origin in the gla- dae, Sciardae and Mycetophilidae. Fungus cier Jostedalsbreen, the largest ice cap on the gnats are distributed all over the world, but European mainland, and runs through the their taxonomy, biology and biogeography valley Jostedalen.

  • Insect Fauna Compared Between Six Polypore Species in a Southern Norwegian Spruce Forest
    --------------------------FaunanorY. Ser. B 42: 21-26.1995 Insect fauna compared between six polypore species in a southern Norwegian spruce forest Bj0rn 0kland 0kland, B. 1995. Insect fauna compared between six polypore species in a southern Norwegian spruce forest. - Fauna norv. Ser. B 42: 21-26. Beetles and gall midges were reared from dead fruiting bodies of the polypore species Phellinus tremulae, Piptoporus betulinus, Fomitopsis pinicola, Pycnoporus cinnabari­ nus, Fomes fomentarius and Inonotus radiatus. The number of species differed signifi­ cantly among the polypore species. The variation in species richness conformed well with the hypothesis that more insect species may utilize a fungi species with (1) increasing durational stability, and (2) increasing softness of the carpophores. Strong preferance for certain polypore species was indicated for most of the Cisidae species, and a few species in the other families of beetles and gall midges (Diptera). The host preferances of the Cisidae species were in good agreement with records from other parts of Scandinavia. The host records in two of the gall midge species are new. Many of the species were too low-frequent for an evaluation of host preferances. Bjf/Jrn 0kland, Norwegian Forest Research Institute, Hf/Jgskolevn. 12, 1432 As, Norway.

(type species Tyrannothroscus rex n.sp.) and Pseudothroscus n. gen. (type species Pseudothroscus balticus n. sp.). Four species are described from Baltic amber: Tyrannothroscus rex n. sp., Pseudothroscus balticus n. sp., Potergus superbus n. sp. and Trixagus parvulus n. sp. Pactopus burmensis n. sp. is described from Burmese amber. A phylogenetic analysis of the known throscid genera is performed. Aulonothroscus Horn and Trixagus Kugelann are shown to be sister-groups, the sister-group of this clade is the genus Pactopus Horn and the sister group of these three genera is the genus Potergus Bonvouloir. The oldest previ- ously known throscids were species belonging to the genera Rhomboaspis Kirejtshuk & Kovalev and Potergosoma Kire- jtshuk & Kovalev, both from Lebanese Amber, 125–135 Mya. The present analysis shows that the extinct Baltic amber genera Jaira Muona and Pseudothroscus belong to clades at least as old as the Lebanese fossils. The Burmese amber fossil Pactopus burmensis, 99 Mya, is considerably older than any of the previously known species belonging to the four extant genera: Pactopus, Potergus, Aulonothroscus or Trixagus.
