Myriophora discalis sp. nov.

(Figs 3.3, 10.7, 16.6, 23.5)

Diagnosis. Female. This species can be easily recognized by the abrupt disc-shaped expansion of the oviscape at the apex (Figs 16.6, 23.5).

Description. Female (Fig. 3.3). Body length 1.86–2.73 mm. Head: Frons dark brown, with 2 pairs of supraantennal 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 brown, rounded under arista. Palpus yellow, normal sized. Labrum normal sized. Labellum swollen. Thorax: Scutum brown. Scutellum brown. Anterior scutellar setae near equal in length to posterior pair. Pleuron light brown; anepisternum with setulae and one large seta. Forefemur yellow. Midfemur yellow. Hind femur yellow with brown patch distally on anterior surface. Wing length 2.14–2.7 mm (Fig. 10.7); costal vein normal; costal length 1.12–1.47 mm; mean costal ratio 0.52. 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 long. Tergite 6 rectangular to slightly narrowing posteriorly; posterodorsal setae on segment 6 shorter than posteroventral setae. Venter of abdomen with dense, long setae. Oviscape (Fig. 16.6) brown, strongly laterally compressed; division between membrane and sclerites obscure because of extensive fusion; apex of oviscape abruptly expands into a disc-like shape.

Distribution. Colombia and Venezuela.

Host. Unknown.

Etymology. An adjective from Latin for "disc-like" referring to the disc-shaped apex of the oviscape.
