Type of genus: Mythicomyia rileyi Coquillett, 1893, monotypy. Melander (1902), pp. 337-338, treats Mythicomyia as an empidid. Melander (1961). pp. 163-179, key to 136 species and subspecies. Very minute flies, seldom more than two millimeters in length and often much less. Males are very strongly humpbacked and darker in color, lience sexes are not easily associated. They are distinguished from Glahel- lula Bezzi by the presence of a complete discal cell and by the strongly holoptic eyes of the male. In addition, the abdomen is much more slender, somewhat length- ened and attenuate compared to the short, stout, robust, plump abdomen of Glabellula Bezzi. The antennae are longer, more slender and attenuate upon the style of the third segment. The wing is strongly widened basally so that the axillary lobe is triangular with a rounded angle. Anal cell narrowly open, sometimes closed in the margin. In both genera the second vein is very short but well formed, ending in the first vein much like a cross- vein resulting in a short, triangular marginal cell. This genus has had a checkered history. Its author, Coquillett (1893), founded it upon a single specimen, he named rileyi, and placed it within the Empididae. Melander (1902) in his review of the Empididae kept it within this family and made it the basis of the sub- family Mythicomyiinae, for flies with abbreviated sec- ond vein. Greene (1924) was the first to review the var- ious changed allocation of the genus, noting that Wil- liston, Osten Sacken, and Schiner located the genus within the Rhagionidae (Leptidae of authors).
