Myriophora curvicacumen sp. nov.

(Figs 3.1, 10.5, 16.4)

Diagnosis. Female. The oviscape is sclerotized, shiny and tubular throughout most of its length. At the apex, it abruptly becomes laterally flattened and downturned (Fig. 16.4), rendering this species easily distinguishable from all other species of Myriophora.

Description. Female (Fig. 3.1). Body length 1.58 mm. Head: Frons brown, 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 above lower interfrontal setae. First flagellomere yellow, slightly pointed under arista. Labrum normal sized. Labellum normal sized. Thorax: Scutum dusky yellow. Scutellum dusky yellow. Pleuron yellow; anepisternum bare. Forefemur yellow. Midfemur yellow. Hind femur yellow with brown patch distally on anterior surface. Wing length 1.51 mm (Fig. 10.5); costal vein normal; costa length 0.85 mm; costal ratio 0.54. 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 divided in half; posterodorsal setae on segment 6 shorter than posteroventral setae. Venter of abdomen bare, but potentially a few differentiated setae. Oviscape (Fig. 16.4) weakly laterally compressed throughout; division between light brown membrane and dark brown sclerites obscure, as most of oviscape is fused into a shiny tube.

Distribution. Known from one site in Colombia.

Host. Unknown.

Etymology. A noun from Latin for "curved apex" referring to the abruptly, ventrally pointed end of the oviscape.
