New Genera of South American Thynninae (Tiphiidae, Hymenoptera)

The taxonomy of South American thynnines, as with many neotropical insect groups is badly in need of revision. Many of the genera, particularly Elaphroptera and Scotaena, are dumping grounds for species that did not fit other generic concepts. As part of our revision of this subfamily it became clear that quite a number of species placed in these groups belongedin separate genera. To accommodate these monopyletic groups we are describing seven new genera. Specimens used in this study were borrowed from the following individuals and institutions: Bohart Museum of Entomology, University of California, DAVIS, U.S.A. (R. O. Schuster, S. L. Heydon); C. Porter private collection, Gainesville, Florida, U.S.A.; Canadian National Insect Collection, Agriculture Canada, Ottawa, Ontario (L. Masner); Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, U.S.A. (J. E. Rawlins); Department of Entomology, Cornell University, Ithaca, New York, U.S.A. (J. Leibherr); Florida State Collection of Arthropods, Gainesville, U.S.A. (L. A. Stange); Fundaci6n Miguel Lillo, Tucuman, Argentina (A. Willink); Insect Taxonomy Lab., California Department of Food and Agriculture, Sacramento, U.S.A. (M. S. Wasbauer); Los Angeles County Museum, Los Angeles, U.S.A. (R. R. Snelling); Manfredo Fritz, private collection, Salta, Argentina; Museo Argentino de Ciencias Naturales Bernardino Rivadavia,
