(Figs 7.8, 13.10, 19.10) Diagnosis. Female. Myriophora simplex is recognized by the combination of oviscape sclerites that extend greatly over the lateral face, membrane striations that are parallel throughout the oviscape (Fig. 19.10, 24.7), only a few setulae on the anepisternum, and uniformly colored hind femur. Description. Female (Fig. 7.8). Body length 2.91–3.71 mm . Head : Frons brown, with 1 pair of supra-antennal setae; supra-antennals originate above lower interfrontal setae. First flagellomere yellow-brown, rounded under arista. Palpus yellow-brown, normal sized. Labrum prominent, enlarged. Labellum normal sized. Thorax : Scutum light brown. Scutellum light brown. Anterior scutellar setae about 3/4 of the length of posterior pair. Pleuron light brown; anepisternum with many setulae. Forefemur yellow. Midfemur yellow. Hind femur yellow (Fig. 21.21). Wing length 3.08–3.82 mm (Fig. 13.10); costal vein normal; costal length 1.93–2.63 mm ; mean costal ratio 0.65. Knob of halter brown.

Tergite 6 greatly narrowed posteriorly; posterodorsal setae on segment 6 equal in length to posteroventral setae. Venter of abdomen with dense, long setae. Oviscape (Fig. 19.10) sclerites reddish-brown; membrane yellowish; sternite nearly as long as tergite and extending nearly halfway up lateral face. Distribution.
