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 SOUTHOF THE UNITED STATES 46FAMILY SYRPHIDAE F. Christian ThompsonThe American Museum of Natural History, New York, New York, U-S.A. J. R. VOCKEROTHEntomology Research Institute, Canada Department of Agriculture,Ottawa, CanadaYale S. SedmanDepartment of Biological Sciences, Western Illinois UniversityMacomb, Illinois, U.S.A. Adult Syrphidae, commonly called "Flower or Hover Flies", arerather conspicuous flies. Their size ranges from 4 mm to over 25 mmand their coloration from bright yellows and oranges to dull drab blacksand grays with a few iridescent forms. Many syrphid flies are Batesianmimics 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 haveoccasionally been reported to cause intestinal myiasis in man (Eristalis),and some of the predaceous syrphines are of importance in the controlof 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 diversityand the critical zoogeographic importance of the Neotropical area, theSouth American forms are still poorly known. The higher classificationof the Neotropical Syrphidae has been recently revised in large part byVockeroth (1969, tribes of Syrphinae, genera of Syrphini) and Thompson(1969, Microdontinae; 1972, Milesiinae), but much still needs to be doneon 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 includedCentral America. Kertesz (1910) provided a World catalog but hiswork 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 catalogto the Neotropical Syrphidae. However, as is usual with any such firstattempts, there were numerous errors of both omission and commissionin it. Goot (1946) reviewed Fluke's catalog, corrected some of hisomissions, but still missed about a dozen species and caused additionalconfusion by introducting a few unnecessary names.The present catalog is hopefully an improvement over Fluke's workbut the large part of the credit for this improvement is due to hispioneering work and Goot's corrections. Besides the corrections of earliererrors, the other improvements in the present catalog stem from theuse of a new higher classification of the family, as mentioned above.As a result our work, which tends to recognize distinct genera for theNeotropical species rather than to include them in worldwide genera asdid 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 somehave escaped our notice. Many of the synonymies and combinationsinvolving species of the earlier workers are based on the work ofVockeroth, who studied types of their species during trips to Europein 1969 and 1971. Some of the other changes resulted from a shortvisit to the British Museum (Natural History) by Thompson and theloan of selected! types by various curators to him. For all the graciouscooperation we received during our studies, we are very grateful tothose 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 anindication of the number of types, followed by the sex of the type ortypes and end with an abbreviation for the depository. The singular,type, is used when the species was described from a single specimen ora holotype or lectotype was or has been designated [in the case oflectotypes, reference to the designation is given] ; the plural, types, whenthe species was described from a series and no lectotype has beendesignated; and "type(s)" when we are uncertain of the number oftypes incolved. The sex of the type or types is indicated by a sexsym-bol or query when the sex is unknown. The types are assumed tobe where they were reported to be deposited either in the originalpublication or in other references (such as Horn & Kahle, 1935-37; Sacht-leben, 1961; Byers et al., 1962; and Zimsen, 1964). In cases of doubtabout the depository of a type a quesy is added after the abbreviationfor depository and when the depository is unknown only a query is used.All types seen by the authors are marked with an asterisk after thedepository abbreviation. In a few cases where the type is missing, lostor destroyed this information is included in parentheses after the abbre-viation and with either a reference to the source of the information orinitials, which indicates which one of us has noted it.AMNH The American Museum of Natural History, New York(P.
