Encarsia capensis n. sp. ( Figures 73–75 ) Description Female. Colour: head yellow, posterior head with faint brown transverse band, stemmaticum with three small brown spots adjacent to ocelli. Body yellow except pronotum, mesoscutal midlobe anteriorly, and axillae anteriorly slightly brown. Fore wing hyaline. Legs yellow. Figures 73–75. Encarsia capensis n. sp. , female. (73) Mesosoma and gaster. (74) Antenna. (75) Fore wing. Morphology [measurements of holotype in square brackets]: stemmaticum with rugose surface sculpture. Antennal formula 1,1,3,3. Pedicel shorter than F1 (0.86–0.87) [0.86]. F1 2.0–2.14 [2.0] times as long as broad, subequal in length to F2 and slightly longer than F3 (1.07–1.10) [1.10]. Flagellomeres with the following numbers of sensilla: F1: 1–2, F2: 3, F3: 3, F4: 3, F5: 3, F6: 2–3. Midlobe of mesoscutum with 10 setae, arranged symmetrically, side lobes with three setae each. Scutellar sensilla very close together, separated by a distance of less than half the width of a sensillum. Distance between anterior pair of scutellar setae distinctly smaller than between posterior pair. Fore wing 2.4–2.5 [2.4] times as long as width of disc, evenly and densely setose. Marginal fringe 0.19–0.21 [0.19] times as long as width of disc. Submarginal vein with two setae, marginal vein anteriorly with six setae. Basal cell with 8–11 setae. Tarsal formula 5-5-5. Apical spur of midtibia longer than half the length of the corresponding basitarsus (0.73–0.77) [0.77]. Tergites laterally with the following numbers of setae: T1: 0, T2: 1, T3: 1, T4: 1, T5: 3, T6: 3, T7 with four setae. Ovipositor distinctly shorter than midtibia (0.77–0.85) [0.77] and 1.34–1.39 [1.39] times as long as clava. Third valvula 0.51–0.53 [0.51] times as long as second valvifer. Male . Unknown. Species group placement. E. strenua group. Distribution. Australia : Western Australia . Host. Unknown. Material examined Western Australia : Holotype : ♀ , Cape Arid National Park , Yokinup Bay area , 31 December 1986 to 3 January 1987 ( J. S. Noyes ) ( ANIC ); 1♀ , same data as holotype ( BMNH ) . Comments The species can be separated from other members of the strenua group by its relatively short ovipositor.
