Encarsia prolata n. sp. ( Figures 235–237 ) Description Female. Colour: head and mesosoma yellow, gaster brown. Antenna yellow, clava brown (at least apical segment slightly brown). Fore wing with dark band behind marginal vein. Legs yellow. Morphology: stemmaticum with transverse, rugosely strigose surface sculpture. Antennal formula 1,1,4,2. Antenna slender, pedicel distinctly shorter than F1 (0.46–0.55). F1 4.0– 4.4 times as long as its maximum width, subequal in length to F2 and F3. Flagellomeres with the following numbers of sensilla: F1: 0–1, F2: 2, F3:3, F4: 3–4, F5: 2, F6: 2. Midlobe of mesoscutum with (7–)8–10 setae, side lobes with two setae each. Scutellar sensilla widely separated (approximately four to five times the maximum width of a sensillum). Distance between anterior pair of scutellar setae smaller than distance between posterior pair. Fore wing 2.5–2.6 times as long as width of disc. Marginal fringe 0.17–0.25 times as long as width of disc. Submarginal vein with two or three setae, marginal vein anteriorly with seven or eight setae. Basal cell with five or six setae.
