Hypopygium mainly as in latifemorata, perhaps a little larger, not shining below; anal tube as in latifemorata. Legs yellow, hind tibiae and tarsi slightly darker, middle coxae with a black spot behind, and hind femora blackish at apex; the hind femora less dilated than in latifemorata and not broad towards apex, the dorsal margin there- fore evenly curved from the middle towards both ends; hind femora haired as in latifemorata and hind tibial bristles similar, the arrange- ment mentioned under latifemorata generally well marked. Wings brownish, but less strongly than in latifemorata; costa reaching beyond the middle, 1 generally shorter than 2, but variable and sometimes a little longer; costal cilia moderately short to moderately long; fourth vein a little less curved than in latifemorata. Halteres yellow. Female. Similar to the male, but often paler; antennae smaller; the abdominal tergites of a special shape (fig. 81), the second tergite has the sides with the bristles somewhat protruding, but is narrowed behind, the third tergite is semi- circular or trapezoidal, the fourth is narrow, trapezoidal, most narrow in front, sometimes pointed so that the incision here reaches to the middle line, the fifth tergite is a little broader, the sixth again somewhat narrower so that these three tergites form together an elliptical plate; such is the shape in extreme cases, but often the tergites are broader so that the constriction is less marked, only resulting in the tergites after the second being somewhat narrowed; on the ventral side abdomen has bristly hairs at the hind margins of third to sixth segments; hind femora haired as in the male and the hairs below the basal half as long as in this sex. Length 1,7—2,8 mm. A. ruficornis is common in Denmark; Ermelund, Dyrehaven, Lyngby Mose, Holte, Ruderhegn
