Costa 0.54 wing length. Halter brown. Abdominal tergites brown posterolaterally, normal sized. Tergite 6 yellowish-brown, about as broad as tergite 5, entire, apical margin slightly concave, with one thick posterolateral setae and scattered thin setae. Segment 6 with enlarged posterolateral dorsal seta. Venter of abdomen whitish yellow, venter of segments 3–5 with posterolateral row of relatively long setae. Venter of segment 6 lacking sclerite, with smaller posterior setae and row of evenly-spaced longer setae. Venter of intersegment 6–7 with long lateral setae. Oviscape elongate oval, anterior process short, broadly rounded. Dorsum of oviscape with scattered dorsolateral setulae on apical onequarter and long seta dorsally and ventrally at base of separation of dorsal and ventral lobes. Apex broadly rounded, slightly downturned, lacking dorsoapical setae. Ventral apex broad, abruptly narrowed to slightly downturned point. Intersegment 7–8 without sclerotization. Anterior arms of stylet anteriorly divergent, abruptly directed medially at anterior apex, stylet slightly curved in lateral view.
