Hash, John M. & Brown, Brian V., 2015, Revision of the New World Species of the Millipede-Parasitic Genus Myriophora Brown (Diptera: Phoridae), Zootaxa 4035 (1), pp. 1-79 : 24-25

Myriophora gobaleti sp. nov.

(Figs 4.2, 11.2, 17.2, 23.6)

Diagnosis. Female. This species is immediately recognizable among all Myriophora by the heavily sclerotized oviscape that terminates in a triangular, "fishtail-like" shape (Figs 17.2, 23.6).

Description. Female (Fig. 4.2). Body length 1.86–2.24 mm. Head: Frons brown, with 2 pairs of supraantennal setae; length of lower supra-antennal setae less 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, slightly inflated. Labrum normal sized. Thorax: Scutum brown. Scutellum brown. Anterior scutellar setae less than 1/2 the length of posterior pair. Pleuron dusky yellow; anepisternum with setulae and one large seta. Forefemur yellow. Midfemur yellow. Hind femur yellow with brown patch distally on anterior surface. Wing length 1.51–2.35 mm (Fig. 11.2); costal vein normal; costal length 0.98–1.05 mm; mean costal ratio 0.52. 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 dense, long setae. Oviscape (Fig. 17.2) light brown and darker toward apex, membrane and sclerites apparently fused, with only some striations visible in basal half; apex of oviscape abruptly expands resembling a fish tail or base of a triangle.

Distribution. Brazil, Colombia, Ecuador, and Venezuela.

Host. Unknown.

Etymology. Named for ichthyologist and Hash's longtime friend and undergraduate thesis advisor, Dr. Kenneth Gobalet, in appreciation of years of mentorship.
