Description

Female. Colour: head and mesosoma yellow except pronotum, anteromedial patch on mesoscutal midlobe brown. Metasoma pale, T1 with transverse brown band and following tergites laterally more or less brown. Antenna yellow. Fore wing hyaline. Legs yellow.

Morphology: stemmaticum with reticulate surface sculpture. Antennal formula 1,1,3,3. Pedicel longer than F1 (1.14–1.29). F1 2.00–2.30 times as long as its maximum width, shorter than F2 (0.84–0.88), and shorter than F3 (0.80–0.84). F2 subequal in length to F3. Flagellomeres with the following numbers of sensilla: F1: 0, F2: 3–4, F3: 2–3, F4: 3, F5: 3, F6: 3. Midlobe of mesoscutum with four (to six) setae, arranged symmetrically. Scutellar sensilla widely separated (approximately 10–15 times the maximum width of a sensillum). Distance between anterior pair of scutellar setae greater than between posterior pair. Fore wing 3.5–3.9 times as long as width of disc, occasionally with sparsely setose area near anterior margin proximal to stigmal vein. Marginal fringe 0.75–1.00 times as long as width of disc. Basal cell with one seta. Submarginal vein with two setae, marginal vein anteriorly with five setae. Tarsal formula 5-5-5. Apical spur of midtibia subequal to half the length of the corresponding basitarsus (0.49–0.56). Tergites laterally with the following numbers of setae: T1: 0, T2: 1, T3: 1(–2), T4: 1(–2), T5: 1–2, T6: 3, T7 with four setae. Ovipositor very short and only slightly longer than half the length of the midtibia (0.55–0.60) and 0.64–0.66 times as long as clava. Third valvula 0.36–0.44 times as long as second valvifer.

Male. Similar in colour and morphology to female. Flagellum six-segmented, all segments with abundant sensilla.

Species group placement. E. lahorensis group.

Distribution. Australia: Northern Territory, Western Australia.

Host. Aleyrodidae : Dialeuropora decempuncta (Quaintance and Baker) .
