(Figs. 102–106, 221)  
 Description. As described for A. nitidicollis. Male with microtomentum on frons covering frontal triangle and orbital plates, female with microtomentum on frons covering orbital plates to just anterior of anterior orbital bristle. Anterior genal bristle about 0.5X length of vibrissa, subvibrissal bristle about 0.6X length of vibrissa. Male with thorax entirely covered with microtomentum. Female with microtomentum on lateral and posterior margins of scutum and a spot at the base of anteriormost acrostichals, margins of scutellum, and latero- and mediotergite, thorax otherwise shiny. Acrostichal setae in 6 irregular rows. Microtrichia not reduced at base of wing. Male with abdominal tergites covered with microtomentum, sternites 2–3 covered with microtomentum, sternites 4–5 with a thin band of microtomentum at bases. Female with tergites 1–3 covered with microtomentum, shiny laterally, tergite 4 with microtomentum across basal quarter, tergite 5 shiny, sternites shiny.   
Male postabdomen: Sternite 5 as described for the group. Surstylus with strong medial ridge with 7 setae, setae on ventral tooth strong, anteroventral corner rounded (Fig. 103). Pregonite indistinct, fused with postgonite. Postgonite with anterior lobe relatively long. Preepiphallus narrow. Distiphallus with small, setose dorsal knob (Fig. 102).  
Female postabdomen: Tergites 6–7 and sternites 6–7 wider than long, moderately sclerotized, shiny. Tergites with 3 posterior strips, sternites with 2 posterior strips. Tergite 8 shiny, widest anteriorly, posterior margin emarginated medially, anterior corners nearly meeting sternite 8 laterally. Epiproct with short anterior arms, covered with microtomentum except anterior arms, with 2 pairs of setae, may have some additional unpaired setae (Fig. 104). Cerci long. Sclerites of tergite 8 with anterior portion narrow, pinched, microtomentum restricted to apical sixth, no apical hooks. Hypoproct not distinctly depressed (Fig. 105). Spermathecae round, slightly shorter than wide, with deep apical invagination, no basal invagination, sclerotized duct short (Fig. 106).  
 Type material. Holotype ♂: ECUADOR: Carchi: Guandera For. Res., 15 km E San Gabriel, 3300 m, trail to station, sweeping, 1 Nov 1999, S.A. Marshall, debu00108144 (QCAZ). Paratypes: same data as holotype (27 ♂, 14 ♀, DEBU, QCAZ).   
 Comments. The male of this species is very distinctive within the A. orbitalis group, with most of the body covered with microtomentum. The species name is derived from the type locality and should be treated as a noun in apposition.
