15. Encarsia bifasciata Schmidt and Polaszek

( Figures 51–54 View Figures 51–54 ) Encarsia bifasciata Schmidt and Polaszek 2007, p 86 –87. Holotype ♀, Australia,

Queensland, Forty Mile Scrub, 6 July 2000 (P. De Barro), ex Aleurodicus sp. on

Diospyros sp. (Ebenaceae) (ANIC, examined).

Diagnosis

Female. Colour: head brown, vertex and lower face paler, or pale and malar space and central area more or less brown ( Figure 53 View Figures 51–54 ). Mesosoma brown except mesoscutum anteriorly brown, and metanotum paler. Metasoma brown. Antenna yellow, radicle, pedicel, scape, and clava more or less brown. Fore wing with two narrow dark bands behind marginal vein and base of wing brown. Legs yellow except coxae and base of femur brown.

Morphology: stemmaticum with rugosely strigose surface sculpture. Maxillary palp twosegmented. Antennal formula 1,1,4,2. F1–F5 cylindrical, F6 conical and slightly shorter than or subequal in length to preapical segment. Pedicel subequal in length to or slightly longer than F1 (1.00–1.28). F1 1.47–1.81 times as long as its maximum width, distinctly shorter than F2 (0.54–0.59) and F3 (0.58–0.65). F2 slightly longer than F3 (1.08–1.10). Flagellomeres with the following numbers of longitudinal sensilla: F1: 0, F2: 3, F4: 3, F4: 3–4, F5: 4–5, F6: 3. Midlobe of mesoscutum with about 50–70 setae, side lobes with three setae each. Posterior pair and lateral setae of mesoscutal midlobe larger than remaining setae of scutellum. Scutellum with distinct reticulate surface sculpture. Scutellar sensilla separated by approximately two to four times the maximum width of a sensillum. Distance between anterior pair of scutellar setae subequal to distance between posterior pair. Fore wing 2.1 times as long as width of disc. Basal cell with 17–23 setae. Longest setae of marginal fringe slightly less than one-tenth width of disc. Submarginal vein with three to four setae, marginal vein anteriorly with 10–15 setae. Upper wing surface with several long, downward pointing setae below marginal vein. Apical spur of midtibia longer than half the length of the corresponding basitarsus (0.72–0.73). Basitarsus of middle leg ventrally with stout setae with distinct bases. Metasoma with distinct longitudinally strigose surface sculpture. Tergites on each side with the following numbers of setae: T1: 3–4, T2: 4–7, T3: 5–6, T4: 5–6, T5: 2–7, T6: 3, T7 with three to four setae. Ovipositor subequal in length to midtibia (1.03–1.07). Third valvula very narrow, in addition to several apical setae with six to nine pairs of setae, some of them in its basal half, 0.50 times as long as second valvifer.
