Description (holotype)

Female. Colour: head yellow, postgena brown. Mesosoma brown, mesoscutum (except anteriorly), axillae posteromesally, scutellum, metanotum, and propodeum medially lighter. Metasoma predominantly brown except apex of T7 pale. Antenna yellow, apical segment of clava brown. Fore wing with dark band behind marginal vein. Legs yellow except hind coxa brown.

Morphology: stemmaticum with reticulate surface sculpture. Antennal formula 1,1,3,3. Pedicel longer than F1 (1.54). F1 only very slightly longer than wide (1.18), shorter than F2 (0.65) and F3 (0.59). F2 slightly shorter than F3 (0.87). Flagellomeres with the following numbers of sensilla: F1: 0, F2: 2, F3: 3, F4: 3, F5: 3, F6: 3. Midlobe of mesoscutum with eight setae, side lobes with three setae each. Scutellar sensilla rather closely placed (approximately 1.5 times the maximum width of a sensillum). Distance between anterior pair of scutellar setae smaller than between posterior pair. Fore wing 2.3 times as long as width of disc. Marginal fringe 0.26 times as long as width of disc. Basal cell with four setae. Submarginal vein with two setae, marginal vein anteriorly with seven setae. Tarsal formula 5-5-5. Apical spur of midtibia shorter than corresponding basitarsus (0.80). Tergites laterally with the following numbers of setae: T1: 0, T2: 2, T3: 2, T4: 2, T5: 3, T6: 3, T7 with four setae. Ovipositor slightly longer than midtibia (1.16) and 1.6 times as long as clava. Ovipositor apically modified with several setae. Third valvula 0.7 times as long as second valvifer.
