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.
