Colour: head pale, with dark transverse band. Mesosoma predominantly pale, or brown (with pronotum, mesonotum, and axillae largely darkened). Petiole brown. Gaster predominantly brown. Third valvula pale. Antenna pale with apex more or less darkened. Fore wing with dark band behind marginal vein. Legs pale. Morphology: stemmaticum with reticulate surface sculpture. Antennal formula 1,1,4,2. Pedicel longer than F1 (1.27–1.36). F1 2.50–3.00 times as long as its maximum width, slightly shorter than F2 (0.90–1.00) and shorter than F3 (0.77–0.85). Flagellomeres with the following numbers of sensilla: F1: 0, F2: 0, F3: 1–2, F4: 2, F5: 3, F6: 2. Midlobe of mesoscutum with 8–11 setae, side lobes with two setae each. Scutellar sensilla widely separated (approximately six times the maximum width of a sensillum). Distance between anterior pair of scutellar setae subequal to distance between posterior pair. Fore wing with bare area, 3.4–3.6 times as long as width of disc. Marginal fringe 0.68–0.75 times as long as width of disc. Submarginal vein with two setae, marginal vein anteriorly with seven to nine setae. Tarsal formula 5-5-5. Apical spur of midtibia slightly shorter than half the length of the corresponding basitarsus (0.37–0.41). Tergites laterally with the following numbers of setae: T1: 0–1, T2: 1, T3: 1, T4: 1, T5: 2(–3), T6: 2, T7 with four setae. Ovipositor almost as long as midtibia (0.84–0.91). Third valvula 0.54–0.70 times as long as second valvifer.
