Myriophora porrecta View in CoL sp. nov.

(Figs 7.5, 13.7, 19.7)

Diagnosis. Female. Myriophora porrecta is most similar to M. dolionatis and M. misionesensis but is distinguished by the combination of the longer oviscape sternite that is nearly equal in length to the tergite, the posterior margin of T6 that is wider than the oviscape tergite, and the very similar shape of the oviscape sternite and tergite (Fig. 19.7).

Description. Female (Fig. 7.5). Body length 1.51–2.14 mm. Head: Frons dusky yellow, with 2 pairs of supraantennal setae; length of lower supra-antennal setae less than 1/2 of the length of upper pair; upper supra-antennals originate even with lower interfrontal setae. First flagellomere yellow, slightly pointed under arista. Palpus yellow, normal sized. Labrum prominent, enlarged. Labellum normal sized. Thorax: Scutum dusky yellow. Scutellum dusky yellow. Anterior scutellar setae about 3/4 of the length of posterior pair. Pleuron yellow; anepisternum with few setulae. Forefemur yellow. Midfemur yellow. Hind femur yellow. Wing length 1.58–2.14 mm (Fig. 13.7); costal vein normal; costal length 0.91–1.23 mm; mean costal ratio 0.59. Knob of halter light brown. Abdomen: Tergites 1 and 2 contrasting, yellow anteriorly, brown posteriorly; tergite 2 with strong, distinct setae on lateral margin. Tergite 5 contrasting, yellow anteriorly, brown posteriorly; posterior setae on tergite 5 short. Tergite 6 greatly narrowed posteriorly; posterodorsal setae on segment 6 shorter than posteroventral setae. Venter of abdomen with sparse, long setae. Oviscape (Fig. 19.7) sclerites reddish-brown; membrane brown; strongly laterally compressed; ventral margin of sternite and dorsal margin of tergite parallel in apical half and divergent in basal half.

Distribution. Ecuador and French Guiana.

Host. Collected on unidentified dead millipedes.

Etymology. An adjective from Latin for "extended" referring the longer oviscape sternite relative to the similar species, M. dolionatis .

Holotype. ♀, FRENCH GUIANA: Boeuf Morte, 3.65°N, 53.22°W, 28.iv.1996, A. Berkov, ex. dead millipede [ LACM ENT 101666] ( AMNH).
