Description. Head dark reddish brown, occiput, frons except anterior margin, and gena black. Covered with microtomentum except shiny spots lateral to ocelli and a small ventromedial spot on face. Ocellar bristles about 1 ocellus width anterior to median ocellus. Subvibrissal and anterior genal bristles about 0.25X length of vibrissa. Gena height equal to eye height.

Thorax black. Mostly covered with microtomentum, scutum shiny except anterior and lateral margins and patches anterior to scutellum, dorsal surface of scutellum shiny, proepisternum shiny, anepisternum mostly shiny except dorsal margin beginning at corner of postpronotum and extending along posterior margin, katepisternum with a small shiny spot behind fore coxa. Dorsocentral bristles very short, only posterior bristle at all distinguishable in male, normal in female. Halter mostly whitish, dark brown below knob.

Legs dark brown to black, joints orange. Male with a short spur on fore basotarsomere. Mid tibia with complete rows of stout anterodorsal and posterodorsal bristles in male, posterodorsal bristles fewer and thinner in female, both sexes with 1 anteroventral, 1 posteroventral, 5 subapical bristles. Hind tibia with rows of long thin anterodorsal and posterodorsal bristles, 1 anteroventral, and 3 ventroapical bristles.

Wing light brown, veins brown, crossveins r-m and dm-cu whitish.

Abdominal tergites black, heavily sclerotized, syntergite 1+2 with microtomentum on anterior two-thirds, tergites 3–5 with microtomentum on anterior third. Sternites moderately sclerotized in both sexes. Pleural setae dense, long and pliant.

Male postabdomen: Sternite 5 with curved lateral margins, narrow anteriorly with short narrow anterior apodeme ( Fig. 59 ). Surstylus narrow, scooped. Pregonite partially fused with postgonite. Postgonite with moderately separated lobes, anterior lobe very broad and rounded, posterior lobe narrow and pointed. Basiphallus with moderately long epiphallus, long, rounded preepiphallus. Distiphallus with a strongly curved, spinose dorsal tube, flanked by a single spike-like sclerite, with enlarged ventral sacs ( Fig. 55 ).

Female postabdomen: Tergites 6–7 and sternite 6–7 slightly longer than wide, sclerotized along anterior and lateral margins only, anterior margin shiny. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 longer than wide, anterior margin emarginated, lateral margin wavy, anterior corners shiny. Epiproct with long, barely separated anterior arms, distal part covered with microtomentum, with 2 pairs of setae. Sclerites of sternite 8 narrow, pointed apically, somewhat pinched medially, covered with microtomentum except anterior third. Hypoproct with anterior margin notched, shiny laterally to notch. Spermathecae barrel-shaped, about 1.5X longer than wide, with invaginations, sclerotized duct about as long as spermathecae.

Type material. Lectotype ♂ (designated by Papp (1977)): BOLIVIA: [La Paz:] Cillutincara (HMNH; photos examined) . Paralectotype: same data as holotype (1 ♀, HMNH) .

Other material examined. ARGENTINA: Catamarca: El Suncho, 2200 m, 8–18 Nov 1957, Golbach (1 ♂, USNM) . BOLIVIA: Cochabamba: Serranía de Siberia, along Hwy. 4, 2722 m, cloud forest, bait trap (squid carrion), 17–25 Nov 1993, Parrillo & Rojas (1 ♀, FMNH) ; along Hwy. 7, 3303 m, pine gardens, bait trap (squid carrion), 19 Nov 1993, Parrillo & Rojas (1 ♂, FMNH) ; La Paz: Chuspipata , 3100 m, 19 Mar 2001, A. Friedberg (4 ♂, 2 ♀, USNM) ; Unduavi , 3500 m, grass, pan traps, 5–17 Apr 2001, S.A. Marshall (3 ♀, DEBU) ; as above but moss (1 ♂, DEBU) ; Zongo road, ca. 3800 m, alpine shrub, on cow dung, 18 Apr 2001, S.A. Marshall (3 ♂, 5 ♀, DEBU) .

Comments. The type locality for this species, "Cillutincara", probably refers to Cerro Sillutincara, a moutain range northeast of La Paz along the road to Coroico, or the pre-Columbian trail Sillu Tinkara near Unduavi. This species is most similar to A. baeza ; see that species for discussion.
