World Catalog of the Family Tethinidae (Diptera) m WAYNE N MATHIS and LORENZO MUNARI I SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY ? NUMBER 584 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover. I.

Information on the natural history, as available in the literature, and depository of primary types also are provided. Taxonomic and nomenclatural changes are as follows: The subfamily Apetaeninae Mathis and Munari is proposed, three new combinations are included (Dasyrhicnoessa sexseriata (Hendel), Tethina dubiosa (Collin), and Tethina heringi (Hendel)), one new synonymy (Dasyrhicnoessa asymbasia Sasakawa = Dasyrhicnoessa sexseriata (Hendel)), and Tethina minutissima (Bezzi) is transferred to the family Chyromyidae.
