Myriophora heratyi sp. nov.

(Figs 4.5, 11.5, 17.5, 23.7)

Diagnosis. Female. Myriophora heratyi is differentiated from most species of Myriophora by the bare anepisternum and the strong body setation (Fig 4.5). Myriophora heratyi has a blunt oviscape apex, and the membrane is folded into numerous striations (Figs 17.5, 23.7) differentiating it from the similar M. curvata and M. scopulata , which have acutely pointed apices and fewer than 7 membrane striations.

Description. Female (Fig. 4.5). Body length 2.63–3.12 mm. Head: Frons yellow-brown, with 1 pair of supraantennal setae; supra-antennals originate above lower interfrontal setae. First flagellomere yellow-brown, laterally compressed on distal end. Palpus yellow, slightly inflated. Labrum prominent, enlarged. Labellum normal sized. Thorax: Scutum light brown. Scutellum dusky yellow. Anterior scutellar setae about 3/4 the length of posterior pair. Pleuron dusky yellow; anepisternum bare. Forefemur yellow. Midfemur yellow. Hind femur yellow. Wing length 2.59–2.91 mm (Fig. 11.5); costal vein normal; costal length 1.58–1.79 mm; mean costal ratio 0.62. 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 narrowing posteriorly; posterodorsal setae on segment 6 shorter than posteroventral setae. Venter of abdomen with dense, long setae. Oviscape (Figs 17.5, 23.7) sclerites brown, membrane brown in basal half and white in distal half; tergite with a distinct upward curve in basal half; membrane striations in basal half nearly perpendicular to striations in distal half.

Distribution. Costa Rica and Colombia.

Host. Unknown.
