( Fig. 12 View FIGURES 9 – 16 )

Diagnosis. Venter of segment 6 with fan of thickened, ventromedial setae.

Description. Body length 1.3–1.4 mm. Frons 0.51 head width. Flagellomere 1 round, yellow. Pleuron whitish yellow. Costa 0.55 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 several long thick curved setae; shorter thick setae present more anteriorly on tergite. Venter of abdomen whitish yellow, venter of segments 3–5 with scattered thin setae, longer on segment 5, venter of intersegment 6–7 with rounded, thinly sclerotized plate producing vertical surface in posterior view, consisting of posterior dense comblike row of setae. Venter of segment 6 with large brown sclerite extending to dorsal margin, with scattered short, thin setae. Oviscape elongate oval, anterior process elongate, with dark medial strip, large lateral setae absent. Dorsum of oviscape with long thin setae dorsolaterally to laterally from midlength to near apex. Apex broadly truncate, relatively straight, lacking dorsoapical setae. Oviscape with large ventrolateral seta on each side. Intersegment 7–8 without sclerotization. Anterior arms of stylet broad, similar to A. analis ( Fig. 50 View FIGURES 43 – 51 ).

Distribution. Costa Rica and Colombia.

Derivation of specific epithet. From Latin words for “straight setae”, referring to the large setae on segment 6.
