Diagnosis. With its long dorsoapical setae on the oviscape, this species is similar to A. papei , but the setae of the venter of segment 6 are thicker, shorter, and there is a more pronounced gap between the median pair.

Description. Body length 1.2 mm. Frons 0.48 head width. Flagellomere 1 rounded oval, light brown. Pleuron nearly white. Costa 0.57 wing length. Halter light brown. Abdominal tergites light brown, normal sized. Tergite 6 light brown, about as broad as tergite 5, entire, apical margin slightly concave, posterior margin with few elongate thick setae and scattered setulae. Venter of abdomen whitish yellow, venter of segments 3–5 with scattered thin setae, venter of intersegment 6–7 with rounded, thinly sclerotized plate producing vertical surface in posterior view, with row of thin lateral setae. Venter of segment 6 lacking sclerite, with row of larger thick seta; pronounced gap between median pair. Oviscape elongate oval, anterior process broadly elongate, large, curved posteroventral seta and thinner, shorter, slightly more posterodorsal seta. Dorsum of oviscape with scattered long thin setae. Apex roundly pointed, downturned, lacking apical setae. Ventral setae of oviscape absent. Intersegment 7–8 without sclerotization. Anterior arms of stylet anteriorly reduced, stylet slightly curved in lateral view.

Distribution. Amazonian Colombia.
