Diagnosis. A distinctive species, body color violet-pink with aeneous highlights and a bright yellow face, including fronto-orbital, parafacial, antenna and gena (Fig. 21). All abdominal tergites with microtomentum. The male surstylus is short, broad and digitate (Figs. 43, 44). Known only from the east slopes of the Andes Mountains in Peru, Bolivia, and Argentina.

Description. Male. Frons broad, 0.05 (0.04–0.055/5) of head width at narrowest; anterior facets 1.38x larger than posterior facets (0.40 mm, 0.29mm) this difference is small compared to most other species. Fronto-orbital plate, parafacial, and anterior half of gena yellow-gold in color; remainder of gena gradually darkening posteriorly, gena with dark setae; postgena dark silvery with pale setae. Frontal vitta dull orange, obliterated above; frontoorbital plates broad, meeting midway up frons; upper parafacial broad, equal in width to first flagellomere. Ocellar triangle medium sized anterior ocellus twice the diameter of posterior ocelli, anterior ocellar setae short and stout, no distinct postocellar setae, small dark setae on the rest of the triangle. Frontal setae ascend to about two-thirds of way to vertex; supravibrissal setae ascending about one-third of way up facial ridge. Intrapostocular area bright silvery; setae behind and below stout black row of postocular setae pale and weak; upper edge of occiput black, shining, the remainder covered with pale setae and whitish microtomentum. Thorax color variable, usually purple with pink highlights, but ranging from blue to purple; presutural area of thorax with heavy whitish microtomentum, remainder of thorax and scutellum with weak whitish microtomentum. Thoracic spiracles small, dark brown in color; setae on proepisternal depression usually with pale setae, a few specimens with tan setae. Upper calypter white, lower calypter variable, from white to light tan; basicosta brown, tegula black, veins in wing base darkened, legs dark brown. Surstylus is short, broad, and parallel sided, cerci are short and stout (Figs. 43, 44); phallus as in Fig. 67, 68, hypandrium, pre- and postgonites, ejaculatory sclerite, and sternites as in Figs. 93–95, 125.

Female. Characters like male except frons 0.26 (0.25–0.27/5) of head width at narrowest; eye facets slightly smaller than males, anterior facets 1.65x posterior facets (0.43mm, 0.26mm). Upper and lower calypters white. Ovipositor and spermathecae as in Figs. 137, 149.

Distribution. Specimens were examined from Peru, Junin Region near Chuquisunca, San Felix, San Ramon and Cusco Province near Huadquina and Huancabamba, as well as from Rio Tapia, Tucaman Province, Argentina, Santa Cruz, Bolivia and Nayón Pichincha, Ecuador (Fig. 160). Baumgartner & Greenberg (1985) discussed the distribution of this species in detail.

Discussion. The species is quite distinctive and only known from higher elevations of the Andes Mountains. Aubertin (1933) provided a description of this species. Identified material from the Bernard Greenberg collection (BG) was relied on to confirm this species.
