description: Myriophora borealis sp. nov.
(Figs 2.3, 9.10, 15.10, 21.7, 22.9, 23.3)
Diagnosis. Female. This is species is similar to M. kungae, M. longisetarum, and M. annulata, but is distinguished by the visible, dorsal membrane striations in the basal half of the oviscape where the tergite is separated (Fig. 22.9).
Description. Female (Fig. 2.3). Body length 1.4–2.07 mm. Head: Frons yellow, with 2 pairs of supra-antennal setae; length of lower supra-antennal setae greater than 1/2 the length of upper pair; upper supra-antennals originate even with lower interfrontal setae. First flagellomere yellow, 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 length of the posterior pair. Pleuron yellow; anepisternum with setulae and one large seta. Forefemur yellow. Midfemur yellow. Hind femur yellow with brown patch distally on anterior surface. Wing length 1.44–2.28 mm (Fig. 9.10); costal vein normal; costal length 0.88–1.26 mm; mean costal ratio 0.56. Knob of halter light brown. Abdomen: Tergites 1 and 2 brown; tergite 2 with strong, distinct setae on lateral margin. Tergite 5 brown; posterior setae on tergite 5 short. Tergite 6 rectangular to slightly narrowed posteriorly; posterodorsal setae on segment 6 shorter than posteroventral setae. Venter of abdomen with sparse, long setae. Oviscape (Fig. 15.10) strongly laterally compressed; membrane striations turn nearly 90° from base to apex; tergite separated in basal 1/3, membrane exposed dorsally; sclerites brown; membrane lightly colored with brown striations.
Distribution. Southern Canada, Eastern United States, and Central America.
Host. Spirobolidan millipedes.
Etymology. An adjective from Latin for "northern" referring to the species distribution across much of the Nearctic Region.
