Type species: Ortalotrypeta idana Hendel, 1927 , by original designation.

Diagnosis. General characters similar to Cyaforma Wang. Medium-sized to large flies (body length 5.5–10.5mm; wing length 6.5–9.8 mm) with yellow to orange body. Median carina of face well developed; antenna about 1/2 as long as face or shorter, arista short pubescent; typically with 2–3 postpronotal (except in singula Wang ), 0–1 intrapostalar and 6 strong scutellar setae; ocellar and paravertical setae very strong. Scutum and scutellum entirely yellow, lacking dark markings; wing mixed yellow and hyaline in ground color, typically with a crooked brown to dark brown band running along vein CuA 1, crossvein DM-Cu, 4th section of vein M, apices of cells r 2+3 and r 4+5 (except in trypetoides Chen ); cell sc about 1/2 equal in length to cell c, lobe of cell bcu shortly produced, vein R 4+5 densely setose up to nearly length of vein; R-M crossvein situated beyond middle of cell dm; mid tibia with 2 strong apical spurs.

Female terminalia. Oviscape nearly triangular in shape, less than or equal in length to tergites 5–6, with large dorsoapical opening; eversible membrane with a large ventral area of dark brown to black scales but without basal taenia; aculeus greatly expanded at base, strongly dorsally curved, apically tapered to a point and lacking preapical serrations; 3 pale, subspherical spermathecae present.

Male genitalia. Inner surstylus well developed, outer surstylus nearly rounded at apex in profile.
