M1 distally abbreviated, not reaching wing margin ( Fig. 3 A, 3D, 3G, 3J). Description. Male and female: Eyes red to brownish red. Ocellar triangle dark brown to black, with a pair of setae above ocellar setae. Postocellar seta usually small. Frons brown, narrow, nearly parallel, with a few minute setulae medially. All orbital setae large; proclinate and anterior reclinate orbital setae very close together, separated by distance less than 1/2 of that between anterior reclinate and posterior reclinate. Pedicel yellow; first flagellomere brownish; arista long plumose. Face mostly yellow; facial carina undeveloped. Clypeus yellow. Palpus brownish yellow, slender in both sexes. Vibrissa prominent; other orals small. Gena and postgena narrow. Mesonotum yellow to brown, not pollinose. Postpronotal lobe with 2–4 long setae and a few of shorter setae. Acrostichal setulae in ca. 12–14 irregular rows. Prescutellar setae large. Katepisternum yellowish, with small setae medially, and 2 large ones anteriorly and posteriorly, respectively. Subscutellum swollen. Basal medial-cubital crossvein absent. Wing costal vein between R2+3 and R4+5 distally with more than 5, 6 peg-like spinules on ventral surface; R2+3 sometimes curved to costa at tip. Halter mostly yellowish white. Legs mostly yellowish. Abdominal tergites variable in the color and pattern. Male terminalia: Epandrium usually with sparse pubescence and several setae around posterodorsal to ventral margins; apodeme usually developed ( Figs 5–8 A). Surstylus broad, flat, nearly entirely pubescent, with several setae on outer and inner surface ( Figs 5–8 A). Cercus separated from epandrium, with several setae, lacking pubescence ( Figs 5–8 A). Hypandrium (gonopod in Bächli et al . 2004) anteriorly fused to aedeagal apodeme, laterally broad, usually with paramedian setae subbasally. Gonopods (dorsal arch in Bächli et al . 2004) fused with each other, forming slightly triangular plate, anterioventrally with curved, median rod. Paramere (outer paraphysis in Bächli et al . 2004) contiguous to arm of aedeagal apodeme basally, lacking pubescence ( Figs 5–8 B). Aedeagus glabrous ( Figs 5–8 C); basal bridges contiguous to median rod of gonopod; apodeme with a pair of arms each contiguous to base of paramere. In the following descriptions of each species, only characters that depart from the upper universal characters are provided for brevity.
