Encarsia longifasciata Subba Rao : Hayat 1989a, p 29 –30; Polaszek et al. 1992, p 384; Viggiani and Ren 1993, p 223; Chou et al. 1996, p 198; Hayat 1998, p 192; Huang and Polaszek 1998, p 1906 –1907; Pedata and Polaszek 2004, p 371.

Diagnosis

Female. Colour: head dark brown. Mesosoma yellow, following parts dark brown: pronotum, midlobe of mesoscutum posteriorly and posterolaterally, side lobes anteriorly, axillae except posteriorly, mesopleuron, and propodeum laterally. Gaster yellow, T1–T5 laterally with brown spots forming a narrow stripe. Antenna yellow. Fore wing hyaline, very slightly infuscate behind marginal vein. Legs yellow.

Morphology: antennal formula 1,1,4,2. Pedicel subequal in length to F1. F1 1.83 times as long as its maximum width, shorter than F2 (0.73) and F3 (0.71). F2 subequal in length to F3. Flagellomeres with the following numbers of sensilla: F1: 0, F2: 1, F3: 1, F4: 3, F5: 3, F6: 3. Midlobe of mesoscutum only with posterior pair of setae, side lobes with two setae each. Scutellar sensilla moderately separated (approximately three times the maximum width of a sensillum). Distance between anterior pair of scutellar setae smaller than between posterior pair. Fore wing 2.7 times as long as width of disc, sparsely setose, with distinct bare area near anterior margin proximal of stigmal vein. Marginal fringe 0.47 times as long as width of disc. Basal cell with one to two 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 (0.54). 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 slightly longer than midtibia (1.09) and 1.77 times as long as clava. Third valvula apically truncate, 0.53 times as long as second valvifer.

Male. Unknown.

Species group placement. E. longifasciata group.
