Myriophora bilsae sp. nov.

(Figs 2.1, 9.8, 15.8)

Diagnosis. Female. The combination of few anepisternal setulae and two solidly brown oval spots on abdominal tergite 3 (e.g. Fig. 22.6) differentiate M. bilsae from similar species, such as M. bimaculata .

Description. Female (Fig. 2.1). Body length 2.59–3.15 mm. Head: Frons dusky yellow, with 2 pairs of supraantennal setae; length of lower supra-antennal setae less than 1/2 the length of upper pair; upper supra-antennals originate even with 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 near equal in length to posteriors. Pleuron yellow; anepisternum with a few setulae. Forefemur yellow. Midfemur yellow. Hind femur yellow. Wing length 2.14–2.63 mm (Fig. 9.8); costal vein normal; costal length 1.23–1.65 mm; mean costal ratio 0.60. Knob of halter brown. Abdomen: Tergites 1 and 2 contrasting, yellow anteriorly, brown posteriorly; tergite 2 with strong, distinct setae on lateral margin. Tergite 5 contrasting, yellow anteriorly, brown posteriorly; posterior setae on tergite 5 short. Tergite 6 greatly narrowed posteriorly; posterodorsal setae on segment 6 equal in length to posteroventral setae. Venter of abdomen with dense, short setae. Oviscape (Fig. 15.8) strongly laterally compressed, with small setulae on sclerites and longer setae on apex of membrane; each sclerite covers approximately 1/4 of the lateral face of the oviscape; sclerites brown; membrane light brown, with slightly darker membrane striations.
