VIII. 76 MUSEU DE ZOOLOGIA, UNIVERSIDADE DE SAO PAULO (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 Bepapunent 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 (Humerus and Merodon), others have occasionally been reported to cause intestinal myiasis in man (Hristalis), 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 (1905) included many Neotropical species, since his coverage included Central America. Kertész (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 (Bréthes, 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 symbol 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.
