description: Myriophora uruguaiensis
(Figs 8.6, 14.6, 20.5, 21.16)
Diagnosis. Female. Myriophora uruguaiensis has a long, thin, weakly-compressed oviscape most similar to M. communis but differs in the shape of the sternite, which is shorter and wider, and the overall larger diameter of the oviscape.
Description. Female (Fig. 8.6). Body length 1.37–1.93 mm. Head: Frons dusky yellow with 2 pairs of supraantennal setae; length of lower supra-antennal setae less than 1/2 of the length of upper pair; upper supra-antennals originate even with lower interfrontal setae. First flagellomere yellow-brown, rounded under arista. Palpus yellow, normal sized. Labrum normal sized. Labellum normal sized. Thorax: Scutum dusky yellow. Scutellum dusky yellow. Anterior scutellar setae about 3/4 of the length of posterior pair. Pleuron yellow; anepisternum with setulae and one large seta. Forefemur yellow. Midfemur yellow. Hind femur yellow with a small brown patch on distally on anterior surface. Wing length 1.19–1.75 mm (Fig. 14.6); costal vein normal; costal length 0.70–0.95 mm; mean costal ratio 0.55. Knob of halter light brown. Abdomen: Tergites 1 and 2 contrasting, yellow anteriorly and brown posteriorly; tergite 2 with strong, distinct setae on lateral margin. Tergite 5 contrasting, yellow anteriorly and brown posteriorly; posterior setae on tergite 5 short. Tergite 6 rectangular to slightly narrowing posteriorly; posterodorsal setae on segment 6 equal in length to posteroventral setae. Venter of abdomen with sparse long setae. Oviscape (Fig. 20.5) sclerites brown and thin, weakly laterally compressed, extremely elongate, sternite only about 1/4 to 1/3 as long as tergite and about twice as wide.
