Myriophora perpendicularis sp. nov.

(Figs 7.2, 19.4)

Diagnosis. Female. The oviscape of M. perpendicularis looks most similar to M. smithi , but differs by the shape of the sternite (Fig. 19.4) and the lack of the large, distinct seta on the anepisternum.

Description. Female (Fig. 7.2). Body length 1.79 mm. Head: Frons dusky yellow, with 2 pairs of supraantennal setae; length of lower supra-antennal setae greater than 1/2 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 yellow. Scutellum yellow. Anterior scutellar setae about 3/4 length of posterior pair. Pleuron yellow; anepisternum with many setulae. Forefemur yellow. Midfemur yellow. Hind femur dusky with brown patch distally on anterior surface. Wing length 2.17 mm; costal vein normal; costal length 1.19 mm; costal ratio 0.55. Knob of halter 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 narrowing posteriorly; posterodorsal setae on segment 6 shorter than posteroventral setae. Venter of abdomen with sparse short setae. Oviscape (Fig. 19.4) sclerites reddish-brown; membrane lightly colored with conspicuous brown striations that are dorsoventrally directed in the basal 1/5 and longitudinally directed afterward.

Distribution. Known from one site in Honduras.

Host. Unknown.

Etymology. A noun from Latin for "perpendicular" referring to the roughly 90° angled turn the oviscape membrane striations take from anterior to posterior end.
