A NEW CLASSIFICATION OF THE SEPEDON GROUP OF THE FAMILY SCIOMYZIDAE (DIPTERA) WITH TWO NEW GENERA 1 George C. Steyskal 2 This new classification of the genera related to Sepedon Latreille is presented at this time in order to define new genera to be used in further work on the group and as a preliminary to a catalogue of the neotropical species. Among the Tetanocerini as defined by me (Steyskal, 1965), the group of genera distinguished by the following characters has been designated as the Sepedonini by Acloque (1897:481), and by various later authors as Sepedontini (incorrectly formed), Sepe-donina, Sepedoninae, and even Sepedonidae: Vallar bristles present (on ridge immediately below wing); lunule well exposed; ocellar bristles small and weak or lacking; scutellar bristles 2; face more or less extended below. I do not believe that this group is sufficiently distinct from more typical Tetanocerini, especially from such genera as Hedria and Dichetophora, to be given the rank of tribe or even subtribe. I would prefer to call it merely "the Sepedon group." The African genus Tetanoptera Verbeke (1950:18) was placed by its author in the Tetanocerinae rather than in the Sepedoninae, but with the statement that it is intermediate between those two groups. The genus is based upon a single female specimen. When a male is available, I believe that the genus will be found synonymous with Sepedon.
