Type locality. Chile, Valdivia .

Redescription ♀. Medium sized (11.5–14 mm); body light brown to brown; thorax with two dark brown lateral stripes, contrasting with more distinct center stripe (in some specimens the contrast is not so evident) ( Fig. 4 A–B); abdomen light brown with a median row of white triangles extending to lateral incisures on posterior margins of tergites (lost in some specimens) ( Fig. 4 A,E); Frons, subcallus, parafacial, face, gena and occiput grayish ( Fig. 4 C–D); frons parallel-sided, predominantly with brownish hairs and some sparse yellow hairs (some specimens are the opposite, predominantly yellow hairs and some brownish) ( Fig. 4 C); face reduced, no longer than insertion of antenna (in one specimen little longer than insertion) ( Fig. 4 D); beard white (yellowish in some specimens); Antenna, scape and pedicel light brown with black hairs contrasting with dark brown almost black flagellum; eight well defined flagellomeres (sometimes flagellomeres 2–3 are fused); palpus dark brown, variable in shape and size, first segment subequal to second or a little longer than second, apex of second clavate or more cylindrical; proboscis two times longer than height of head; legs yellowish brown, except for shiny brown trochanters; wing infuscated with clouds on cross-veins (clouds vary from clear to dark), cell r5 with long petiole ( Fig. 4 F); terminalia in posterior view as in figure 4G; internal characters were described in diagnosis of genus ( Fig. 5 A–C).

Male. Unknown.

Holotype. ♀ lost, according Philip (1968:12): “ M. brevirostris . No type was located by Kuschel or during my recent research ”.

Distribution. Chile (Ñuble, Arauco, Osorno, Valdivia ), Argentina (Neuquén).

Material examined. ARGENTINA, Neuquén, P. Nac. Lanín, Lago Hermoso , xi.1949, M. Barrera (♀ MZUSP) ; idem, Pucará, Lago Lácar , i.1954, Duret (2♀ MZUSP) ; idem, Pucará, P. Nac. Lanín, xi.1951, Schajovskoi (♀ MZUSP); CHILE, Alt Sammlung , Mycteromyia brevisrostris (Phi) det. C.B. Philip [19]64 (♀ CAS) ; Arauco, Pichinahuel, cord. Nahuelbuta , 28.i.1954, L.E. Peña (♀ CAS); idem, ibidem, 20km W. Caramavida, 31°42’S –73°21’W, 750m, 31.i. [19]67, E.I. Schlinger (2♀ CAS).

Comments. The holotype, deposited in the MNHNS, is probably destroyed. Philip (1968) searched for the type in Philippi’s material but it was not located and is probably non-extant.
