THE ZOOEOGRAPHIC DISTRIBUTION OF KNOWN SCENOPINIDAE (Diptera) 1 Lewis P. Kelsey 2 A great deal of progress has been made toward the identification and classification of Scenopinidae since I first began work on the family a little over 10 years ago, illustrating the terminalia of all type specimens described to that time. When all proven synonomies were disposed of, a residue of 92 species remained as the core of the known described species. Included in this are three species which, I believe, are undoubtedly synonyms but were retained because the types were unobtainable for study. There are three species described by Loew and three described by Becker, from Persia, Iran and the U.S.S.R., which have never been figured in any way, and must be presumed to be lost, as Krober who figured the heads and wings of most known species, did not figure them either. At the present time there are 300 known species in 18 genera and four subgenera published or in press, Table 1 . Regional Distribution The Palearctic region is only represented by species from the European and Mediterranean portions of the region-no representatives of the family have been seen which come from east 1 Published as Miscellaneous Paper No. with the approval of the Director of the Delaware Agricultural Experiment Station.
