Gaster yellow. Antenna yellow, apex slightly darker. Fore wing hyaline. Legs yellow. Morphology [measurements of holotype in square brackets]: stemmaticum with rugosereticulate surface sculpture. Maxillary palp two-segmented. Antennal formula 1,1,3,3. Pedicel slightly shorter than or subequal to F1 (0.81–0.96) [0.81].

Flagellomeres with the following numbers of sensilla: F1: 0, F2: 0, F3: 1–2, F4: 2–3, F5: 2–3, F6: 3. Midlobe of mesoscutum with 10 setae, side lobes with three setae each. Scutellar sensilla close together, separated by a distance of about the width of a sensillum or less. Distance between anterior pair of scutellar setae distinctly smaller than between posterior pair. Fore wing 2.5–2.7 [2.5] times as long as width of disc. Marginal fringe 0.18–0.20 [0.20] times as long as width of disc. Submarginal vein with two setae, marginal vein anteriorly with seven or eight setae. Basal cell with 10–11 setae. Tarsal formula 5-5-5. Apical spur of midtibia longer than half the length of the corresponding basitarsus (0.78–0.81) [0.78]. Tergites laterally with the following numbers of setae: T1 : 0, T2 : 1, T3 : 1, T4 : 1, T5 : 2, T6 : 3, T7 with four setae.
