Myriophora misionesensis sp. nov.

(Figs 6.1, 12.6, 18.7, 21.18, 24.3)

Diagnosis. Female. Myriophora misionesensis is most similar to M. porrecta but differs by the narrower posterior margin of the abdominal T6 and the shape of the oviscape sternite that is deeper in the proximal half gradually becoming shallower apically (Figs 18.7, 24.3).

Description. Female (Fig. 6.1). Body length 1.86–2.77 mm. Head: Frons dusky yellow, with 1 pair of supraantennal setae; supra-antennals originate above lower interfrontal setae. First flagellomere yellow, slightly pointed under arista. Palpus yellow, normal sized. Labrum prominent, enlarged. Labellum normal sized. Thorax: Scutum dusky yellow. Scutellum dusky yellow; anterior scutellar setae about 3/4 as long as posterior pair. Pleuron yellow; anepisternum with few setulae. Forefemur yellow. Midfemur yellow. Hind femur yellow. Wing length 1.72–2.17 mm (Fig. 12.6); costal vein normal; costal length 0.95–1.44 mm; mean costal ratio 0.60. Knob of halter light brown. Abdomen: Tergites 1 and 2; tergite 2 with strong, distinct setae on lateral margin. Tergite 5 brown; posterior setae on tergite 5 short. Tergite 6 greatly narrowed posteriorly; posterodorsal setae on segment 6 shorter than posteroventral setae. Venter of abdomen with sparse, long setae. Oviscape (18.7) sclerites brown; membrane light brown; strongly laterally compressed; division between membrane and sclerites clearly defined; sternite about 3/4 as long as tergite.
