Diagnosis. This species is similar to A. gonzalezae , with a single row of ventral setae, large lateral setae, and a downturned ventral apex, but ventral setae of the posterior margin of segment 6 are longer and thicker than in that species.

Description. Body length 1.1–1.3 mm. Frons 0.44 head width. Flagellomere 1 rounded oval, light brown. Pleuron light brown. Costa 0.5 wing length (both specimens). Halter light brown. Abdominal tergites light brown, normal sized. Tergite 6 light brown, about as broad as tergite 5, entire, apical margin straight, with one thick posterolateral setae and scattered thin setae. 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. Venter of segment 6 lacking sclerite, with row of larger thick seta; pronounced gap between median pair. Oviscape elongate oval, anterior process short, broadly rounded, with large lateral seta present. Dorsum of oviscape with three posterolateral setae. Apex roundly pointed, strongly downturned, lacking dorsoapical setae. Ventral setae of oviscape absent. Intersegment 7–8 without sclerotization. Anterior arms of stylet anteriorly parallel, well separated, stylet downturned at midlength.

Distribution. Amazonian Brazil.

Derivation of specific epithet. Named for Francisco Felipe Xavier-Filho in thanks for his help in field work.
