( Fig. 20 A–E)

Locus typicus: USA, Texas, Houston, City Park. Holotype: Male , 15.ii.1996, leg. I. Eue, yellow trap ( PWMP) . Paratype: 2 males, same data ( PWMP) .

Further material: 1 male, 3.–6.xi.1996, leg. W. Mohrig, Texas, Houston, Tiki Islands, 25 mi SE Houston , yellow trap ; 1 male, 21.–23.vii.1997, leg. W. Mohrig, USA, Virginia, Williamsburg , mixed forest, yellow trap ( PWMP) .

Description. Male. Head. Eye bridge 2–3 facets wide. 4th flagellomere with l/w-index 2.4, haired longer than wide; neck rather long. Palpus 3-segmented, short; basal segment with slightly deepened sensory area and 1–2 bristles. Thorax. Brown; scutum haired brown. Wings pale; R1: R = 0.5; c somewhat longer ½ w; y nearly 1/ 2 x, bare; posterior veins bare. Haltere short, brownish. Legs yellowish brown; tibial organ of fore tibia small, comblike; spurs of middle and hind tibiae with long, but unequal spurs; claws toothless. Abdomen. Brown, haired brownish.
