Type locality. Chile, Región de Coquimbo, Provincia de Limarí, Parque Nacional Fray Jorge.

Diagnosis Ƌ. Small (9–10 mm); head and thorax dark gray to dark brown; abdomen with broad yellow lateral margins, centrally a broad black stripe covered with continuous pale triangles with wide bases ( Fig. 2 A–B). Frons, subcallus, parafacial, face, gena and occiput dark gray ( Fig. 2 C–D); frons divergent above, with long black hairs ( Fig. 2 D); face moderately produced, clearly longer than insertion of antenna; beard white. Antenna dark brown, with 8 flagollomeres; palpus dark brown, first segment longer than second, last one cylindrical with apex slightly enlarged; proboscis two times longer than head height; coxae, trochanters and femora dark brown, covered with dark gray pollinosity; tibiae and tarsi yellowish, tarsi covered with dense black hairs in dorsal view; wing infuscated with strong clouds (patches) on cross-veins, cell r5 closed with a short petiole ( Fig. 2 E); terminalia, hypandrium + gonocoxite enlarged, 1.5x wider than long ( Fig. 3 A–B); gonocoxite with lateral projections; gonostylus acuminate with pointed apex ( Fig. 3 A–B); ejaculatory apodeme damaged; parameral sheath conical ( Fig. 3 A–B); epandrium with lateral margins rounded and central area hollowed from anterior margin to mid-half ( Fig. 3 C–D); cercus elongated, longer than mid-longitudinal length of epandrium.

Female. For details see Coscarón & Philip (1979: 448) and comments below.

Holotype. Not examined deposited in CAS, described as female but probably a male (see comments below).

Distribution. Chile, Coquimbo region, Limarí province.

Material examined. “ CHILE, Coquimbo, [Limarí], [Parque Nacional] Fra [y] Jorge , 4–5.xi.1957, L.E. Peña ” “ Mycteromyia ♀ asper Phil. det. C.B. Philip 59” “ Caenopangonia asper (Philip) Ƌ det. Cos & Phil 76” “ Caenopangonia aspera (Philip) Ƌ det. Krolow, T.K. 2012 (Ƌ CAS) .

Comments. C. aspera was described by Philip (1958: 65) as female, but Coscarón & Philip (1979: 448) treated the female as unknown: “ we now have previously unknown females that can be associated readily with males ”, as a result the authors describe briefly the female, but do not provide any illustration. This inconsistency is probably due to the fact that Philip (1958) did not dissect the genitalia for the original description. The labels of examined specimens seem to confirm this idea ( Fig. 2 F). Unfortunately, no females were analyzed in this study and its detailed and illustrated redescription is still pending.

The only specimen examined was the same used by Coscarón & Philip (1979) to describe the male terminalia.
