Description. Head black, face and gena dark brown, frons with some reddish along anterior margin, covered with microtomentum. Clypeus orangish brown, prementum dark brown, maxillary palp brown. Vibrissal and anterior genal bristle barely enlarged, about 0.25X length of vibrissa. Ocellar bristles about 1 ocellus width anterior to median ocellus.

Thorax black, some reddish along margins of sclerites, covered with microtomentum except small shiny ventral strip on anepisternum. Halter yellowish, darker below knob. Presutural and anterior postsutural dorsocentral very short or indistinguishable in males, distinguishable but much shorter than posterior dorsocentral in females.

Legs black, joints and sometimes trochanters orange, tarsi brown to dark brown. Tibia 2 with row of anterodorsal and posterodorsal, 1 anteroventral, 1 posteroventral, and 5 subapical bristles. Tibia 3 with row of anterodorsal, 1 anteroventral, 3 ventroapical bristles. Male forebasotarsomere with a small spur.

Wing light brown, with brown markings along vein R 4+5 distal to crossvein r-m and vein M distal to crossvein bm-cu, and slightly paler spots on crossveins r-m and dm-cu, 3 on vein R 4+5 distal to crossvein r-m, and 1 on vein M between crossveins.

Abdomen with tergites dark brown to black, heavily sclerotized, covered with microtomentum. Sternites weakly sclerotized in both sexes. Pleural setae dense, long, pliant.

Male postabdomen: Sternite 5 longer than wide, narrowed posteriorly with posterior corners produced as thin curved lobes, anterior apodeme short, slightly narrower than external portion ( Fig. 45 View FIGURES 38–45 ). Surstylus narrow, not strongly scooped. Pregonite small but distinct. Postgonite with lobes narrowly separated, both pointed, anterior lobe broader. Basiphallus with short, broad epiphallus, slightly longer, narrow preepiphallus. Distiphallus with short, smooth dorsal tube, ventral point projecting ( Fig. 42 View FIGURES 38–45 ).

Female postabdomen: Tergites 6–7 and sternites 6–7 slightly wider than long, covered with microtomentum, weakly sclerotized medially. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 with anterior margin shallowly emarginated, narrow posteriorly, covered with microtomentum except anterior margin. Epiproct with narrow anterior arms, 2 pairs of setae, distal portion with microtomentum. Cerci thin. Sclerites of sternite 8 pinched medially, distal portion somewhat broader and covered with microtomentum, nearly meeting tergite 8 along lateral margins. Hypoproct subrectangular, somewhat weakly sclerotized medially. Spermathecae round, about as long as wide, with basal and apical invaginations, sclerotized duct about as long as spermathecae.

Type material. Syntypes: CHILE: [Magallanes:] Punta Arenas , 6 Feb 1908 ( SMTD, ZMHB; examined). There are 4 specimens of this species with the same label data in SMTD (2 ♂, 1 ♀, labelled as cotypes) and ZMHB (1 ♂, labelled “Typus”). Duda only mentioned 1 of each sex in his description, but all are labelled as this species in his hand and thus should all be considered syntypes. As all belong to the same, easily identified species, no lectotype is designated here .

Comments. Individuals of this species were common on cow dung during field work around Punta Arenas, and were the only archiborborines collected on that substrate. Although cows are not native to South America and there is no evidence that this species is restricted to mammal dung, there may have been close ecological relationships between archiborborine species such as this and the diverse Patagonian megafauna extant until the late Pleistocene.

This species can be separated from others in the genus based on the entirely microtomentose anepisternum, the row of anterodorsal bristles on the hind tibia and the wing pattern.
