Female
Colour: head yellow, stemmaticum with three small brown marks adjacent to ocelli.

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]. F1 2.46–2.64 [2.46] times as long as its maximum width, slightly shorter than F2 (0.85–0.94) [0.94] and F3 (0.81–0.94) [0.94]. F2 subequal in length to F3. 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.

Tergites laterally with the following numbers of setae: T1: 0, T2: 1, T3: 1, T4: 1, T5: 2, T6: 3, T7 with four setae. Ovipositor longer than midtibia (1.36–1.48) [1.36] and 2.03–2.21 [2.03] times as long as clava. Third valvula 0.32 times as long as second valvifer.
