Description (holotype)

Female. Colour: head brown. Mesosoma yellow except pronotum and anterior half of mesoscutellar midlobe brown. Antenna yellow except apical segment brown. Fore wing hyaline. Legs yellow. Metasoma yellow except T1 with transverse brown band and following tergites laterally with faint brown patches.

Morphology: antennal formula 1,1,4,2. Pedicel longer than F1 (1.57). F1 1.55 times longer than its maximum width, shorter than F2 (0.54) and F3 (0.47). F2 slightly shorter than F3 (0.87). Flagellomeres with the following numbers of sensilla: F1: 0, F2: 0, F3: 2, F4: 3, F5: 3, F6: 3. Mid lobe of mesoscutum with two pairs of setae, side lobes with two setae each. Scutellar sensilla separated by approximately five times the maximum width of a sensillum. Distance between anterior pair of scutellar setae smaller than between posterior pair, anterior setae minute, less than two times the maximum diameter of a sensillum. Fore wing 3.0 times longer than width of disc, with sparsely setose area near anterior margin proximal of stigmal vein. Marginal fringe 0.57 times as long as width of disc. Basal cell with four setae. Submarginal vein with two setae, marginal vein anteriorly with five setae. Tarsal formula 5-5-5. Apical spur of midtibia about half as long as the corresponding basitarsus (0.57). Tergites laterally with the following numbers of setae: T1: 0, T2: 1, T3: 1, T4: 1, T5: 2, T6: 2, T7 with four setae. Ovipositor longer than midtibia (1.50) and 2.37 times longer than clava. Third valvula apically truncate, external sides concave, 0.38 times as long as second valvifer.
