Family Syrphidae 9. VIII. 76 MUSEU DE ZOOLOGIA, UNIVERSIDADE DE SAO PAUU) (Formely Departamento de Zoologia, Secretaria da Agricultura, Sao Paulo) A CATALOGUE OF THE DIPTERA OF THE AMERICAS SOUTH OF THE UNITED STATES 46 FAMILY SYRPHIDAE F. Christian Thompson The American Museum of Natural History, New York, New York, U-S.A. J. R. VOCKEROTH Entomology Research Institute, Canada Department of Agriculture, Ottawa, Canada Yale S. Sedman Department of Biological Sciences, Western Illinois University Macomb, Illinois, U.S.A. Adult Syrphidae, commonly called "Flower or Hover Flies", are rather conspicuous flies. Their size ranges from 4 mm to over 25 mm and their coloration from bright yellows and oranges to dull drab blacks and grays with a few iridescent forms. Many syrphid flies are Batesian mimics of stinging Hymenoptera and are highly beneficial as pollinators. The larvae of most syrphids are of little direct importance to man. A few are pests of Narcissus bulbs (Eumerus and Merodon), others have occasionally been reported to cause intestinal myiasis in man (Eristalis), and some of the predaceous syrphines are of importance in the control of aphids and other Homoptera. Syrphid flies are wordwide in distribution, with their greatest diver- sity of forms in the New World tropics. Despite this interesting diversity and the critical zoogeographic importance of the Neotropical area, the South American forms are still poorly known. The higher classification of the Neotropical Syrphidae has been recently revised in large part by Vockeroth (1969, tribes of Syrphinae, genera of Syrphini) and Thompson (1969, Microdontinae; 1972, Milesiinae), but much still needs to be done on the specific level. The first catalog of Neotropical Syrphidae was written by Williston (1886; corrections, 1887a). Aldrich's Catalogue of North American Dip- tera (19C5) included many Neotropical species, since his coverage included Central America. Kertesz (1910) provided a World catalog but his work on the New World was largely based on Williston and Aldrich. 46.1 Some local catalogs were published (Brethes, 1907 — Argentina; Stuardo, 1946 — Chile), but Fluke (1956-57) provided the first modern catalog to the Neotropical Syrphidae. However, as is usual with any such first attempts, there were numerous errors of both omission and commission in it. Goot (1946) reviewed Fluke's catalog, corrected some of his omissions, but still missed about a dozen species and caused additional confusion by introducting a few unnecessary names. The present catalog is hopefully an improvement over Fluke's work but the large part of the credit for this improvement is due to his pioneering work and Goot's corrections. Besides the corrections of earlier errors, the other improvements in the present catalog stem from the use of a new higher classification of the family, as mentioned above. As a result our work, which tends to recognize distinct genera for the Neotropical species rather than to include them in worldwide genera as did earlier workers, contains many new combinations. This catalog contains about 1,000 new combinations and synonyms. Most of these new changes have been indicated but undoubtedly some have escaped our notice. Many of the synonymies and combinations involving species of the earlier workers are based on the work of Vockeroth, who studied types of their species during trips to Europe in 1969 and 1971. Some of the other changes resulted from a short visit to the British Museum (Natural History) by Thompson and the loan of selected! types by various curators to him. For all the gracious cooperation we received during our studies, we are very grateful to those curators listed below by their respective museums. An attempt is made to list the depository of all the types of Neo- tropical species. These statements about type depositories start with an indication of the number of types, followed by the sex of the type or types and end with an abbreviation for the depository. The singular, type, is used when the species was described from a single specimen or a holotype or lectotype was or has been designated [in the case of lectotypes, reference to the designation is given] ; the plural, types, when the species was described from a series and no lectotype has been designated; and "type(s)" when we are uncertain of the number of types incolved. The sex of the type or types is indicated by a sex sym-bol or query when the sex is unknown. The types are assumed to be where they were reported to be deposited either in the original publication or in other references (such as Horn & Kahle, 1935-37; Sacht- leben, 1961; Byers et al., 1962; and Zimsen, 1964). In cases of doubt about the depository of a type a quesy is added after the abbreviation for depository and when the depository is unknown only a query is used. All types seen by the authors are marked with an asterisk after the depository abbreviation. In a few cases where the type is missing, lost or destroyed this information is included in parentheses after the abbre- viation and with either a reference to the source of the information or initials, which indicates which one of us has noted it.

  • QQR 7 Information Pack
    7th Quinquennial Review of Schedules 5 and 8 of the Wildlife and Countryside Act (1981) Information Pack (version 2.21) 14 May 2021 1 Version 2.2: Four reptiles and two seals removed from the EPS list (Annex 1); one EPS amphibian and two EPS reptiles that are all Endangered removed from Annex 2 – these species were included in Version 2 and/or 2.1 in error. See Annex 1 and Annex 2 for further information. 1. Introduction Every five years, the country nature conservation bodies (Natural England, Natural Resources Wales and NatureScot), working jointly through the UK Joint Nature Conservation Committee (JNCC), review Schedules 5 and 8 of the Wildlife and Countryside Act (WCA) 1981. The review will provide recommendations to the Secretary of State for the Environment, Food and Rural Affairs and to Ministers for the Environment in the Scottish Government and Welsh Government for changes to these schedules2. This is known as the Quinquennial Review (QQR). As part of the QQR, stakeholders are provided with the opportunity to propose changes to the species on the schedules. This Information Pack has been produced for the 7th QQR (QQR 7). It is important to note that this QQR differs from previous ones. The Information Pack explains the new selection criteria, provides a timetable, and explains the process to be used by stakeholders. Contact details of the QQR Inter-agency Group who are managing QQR 7, are listed in Section 5. In addition, the Information Pack provides details of how to complete the online survey through which stakeholders propose new species for inclusion on, or removal of existing species from Schedules 5 and 8, or propose a change to how species are protected on the schedules.

Author: Reemer, Menno Title: Unravelling a hotchpotch : phylogeny and classification of the Microdontinae (Diptera: Syrphidae) Issue Date: 2012-03-13 7 Review and phylogenetic evaluation of associations between Microdontinae (Diptera: Syrphidae) and ants (Hymeno- ptera: Formicidae) Abstract. The immature stages of hoverflies of the subfamily Microdontinae (Diptera: Syrphidae) are known to develop in ants nests, as predators of the ant brood. The present paper reviews published and unpublished records of associations of Microdontinae with ants, in order to discuss the following questions: 1. are alle Microdontinae associated with ants?; 2. are Microdontinae associated with all ants?; 3. are particular clades of Microdontinae associated with particular clades of ants? A total number of 103 records of associations between the groups are evaluated, relating to 42 species of Microdontinae belonging to 14 (sub)genera, and to 58 species of ants belonging to 23 genera and four subfamilies. Known associations are mapped onto the most recent phylogenetic hypotheses of both ants and Microdontinae. The taxa of Microdontinae found in association with ants appear to occur scattered throughout their phylogenetic tree, and one of the supposedly most basal taxa (Mixogaster) is known to be associated with ants. This suggests that associations with ants evolved early in the history of the subfamily, and have remained a predominant feature of their lifestyle. When considering the phylogeny of ants, associations with Microdontinae are only known from the subfamilies Dolichoderinae, Formicinae, Myrmicinae and Pseudomyrmecinae, which are all part of the the so-called ‘formicoid’ clade.

  • HOVERFLY NEWSLETTER Dipterists
    HOVERFLY NUMBER 41 NEWSLETTER SPRING 2006 Dipterists Forum ISSN 1358-5029 As a new season begins, no doubt we are all hoping for a more productive recording year than we have had in the last three or so. Despite the frustration of recent seasons it is clear that national and international study of hoverflies is in good health, as witnessed by the success of the Leiden symposium and the Recording Scheme’s report (though the conundrum of the decline in UK records of difficult species is mystifying). New readers may wonder why the list of literature references from page 15 onwards covers publications for the year 2000 only. The reason for this is that for several issues nobody was available to compile these lists. Roger Morris kindly agreed to take on this task and to catch up for the missing years. Each newsletter for the present will include a list covering one complete year of the backlog, and since there are two newsletters per year the backlog will gradually be eliminated. Once again I thank all contributors and I welcome articles for future newsletters; these may be sent as email attachments, typed hard copy, manuscript or even dictated by phone, if you wish. Please do not forget the “Interesting Recent Records” feature, which is rather sparse in this issue. Copy for Hoverfly Newsletter No. 42 (which is expected to be issued with the Autumn 2006 Dipterists Forum Bulletin) should be sent to me: David Iliff, Green Willows, Station Road, Woodmancote, Cheltenham, Glos, GL52 9HN, (telephone 01242 674398), email: [email protected], to reach me by 20 June 2006.

  • Adult Behaviour in Two Species of Cerioicine Flies, Primoerioides Petri (Hervé-Bazin) and Ceriana Japonica (Shiraki) (Diptera S
    1 Adult behaviour in two species of cerioidine flies, Primocerioides petri (Hervé-Bazin) and Ceriana japonica (Shiraki) (Diptera Syrphidae) Toshihide ICHIKAWA & Kenji ŌHARA [Abstract, captions of figs all in English] Introduction Most adult Diptera belonging to the Syrphidae are known to be diurnal pollinators which fly to the flowers of various seed plants and feed on nectar and pollen (1, 2, 3) Many different species have black-and-yellow or black-and-orange stripes and are thought to be simulating female adult Apoidea, which are the most important pollinators and have poisonous stings and similar body stripes (4, 5, 6). A tribe of the Syrphidae, Cerioidini, which we study in this paper, has body stripes similar to none of the Apoidea, but instead simulate Eumenidae or Polistinae, both belonging to the Vespoidea, which are generally called hunter wasps. The Cerioidini includes five genera (Ceriana Rafinesque 1815, Monoceromyia Shannon 1925, Polybiomyia Shannon 1925, Sphiximorpha Rondani 1850 and Primocerioides Shannon 1927) and 197 recorded species worldwide, but for only 19 of which are the life-style and development times known (7). In Japan three species of the Cerioidini are known: recent records of the capture of adult insects show that they occur in Honshū, Shikoku and Kyūshū. Observations of adult Monoceromyia pleuralis (Coquillett) are relatively frequent so it became clear that they visit Quercus acutissima and Ulmus, which exude tree-sap from May to September (8, 9, 10, 11). The lifestyle and life history of the other two species, Primocerioides petri (Hervè-Bazin) and Ceriana japonica (Shiraki), are not known, and so accidental encounters remain the only possibility.
