( Figures 102–105 View Figures 102–105 )

Description

Female. Colour: head yellow except postgena brown. Mesosoma yellow except the following brown: pronotum, mesoscutum anteriorly and anteromedially, axilla anteriorly, mesopleuron, and propodeum. Antenna yellow, apical two segments brown. Gaster brown except T1 and T2 pale and only laterally brown, T3 anteriorly pale, and T6 pale but medially and laterally with brown spot. Fore wing hyaline with very slight, often hardly discernible infuscation behind distal end of stigmal vein. Legs yellow.

Morphology [measurements of holotype in square brackets]: stemmaticum with reticulate surface sculpture ( Figure 104 View Figures 102–105 ). Antennal formula 1,1,3,3. Pedicel longer than F1 (1.18–1.35) [1.18]. F1 1.25–1.38 [1.38] times as long as its maximum width, distinctly shorter than F2 (0.59–0.65) [0.65] and F3 (0.59–0.69) [0.65]. F2 subequal in length to F3. Midlobe of mesoscutum with 10–11 [11] setae, arranged symmetrically. Scutellar sensilla widely separated by a distance of about five to six times the width of a sensillum. Distance between anterior pair of scutellar setae subequal to distance between posterior pair. Fore wing about 2.3 times as long as width of disc. Marginal fringe 0.22–0.24 [0.22] times as long as width of disc. Submarginal vein with two setae, marginal vein anteriorly with six or seven setae. Tarsal formula 5-5-5. Apical spur of midtibia slightly longer than half the length of the corresponding basitarsus (0.65–0.67) [0.67]. Tergites laterally with the following numbers of setae: T1: 0, T2: 1–2, T3: 3–4, T4: 3–4, T5: 3–5, T6: 2, T7 with four setae. T6 with two setae between cercal plates. Ovipositor 1.26–1.28 [1.26] times as long as midtibia and 1.80–1.84 [1.80] times as long as clava. Third valvula 0.38–0.42 [0.40] times as long as second valvifer.

Male. Morphology and colour similar to female except that the brown colour is more extensive so that the axillae are almost completely brown and the hind femur is brown. Petiole with distinct, coarse reticulation.

Species group placement. Tentatively placed in E. elegans group.

Distribution. Australia: Queensland.

Host. Aleyrodidae : Aleurocanthus sp.
