Diagnosis

Female. Colour: head yellow or light brown, stemmaticum with three small brown spots adjacent to ocelli and posterior head with (sometimes faint) transverse brown band. Mesosoma light brown, pronotum, anterior margin of mesoscutellar midlobe, side lobes of mesonotum anteriorly, propodeum, and axilla at anterior corner more or less brown. Gaster light brown, T1–T5 with (sometimes faint) dark bands. Antenna brown, radicle, scape, and pedicel lighter. Fore wing hyaline. Legs light brown except last tarsal segment slightly darker.

Morphology: stemmaticum with reticulate surface sculpture. Maxillary palp twosegmented. Antennal formula 1,1,3,3. Pedicel shorter than or subequal in length to F1 (0.70–1.00). F1 3.00–3.60 times as long as its maximum width, subequal to or slightly longer than F2 (1.00–1.10) and slightly longer than F3 (1.10–1.20). F2 subequal to or slightly longer than F3 (1.00–1.10). Flagellomeres with the following numbers of sensilla: F1: 0–1, F2: 2–3, F3: 2–3, F4: 4–5, F5: 5–6, F6: 3–4. Midlobe of mesoscutum with 16– 22(–27) setae, side lobes with three setae each. Scutellar sensilla close together, separated by a distance of about the width of a sensillum. Distance between anterior pair of scutellar setae distinctly smaller than between posterior pair. Fore wing 2.2–2.5 times as long as width of disc. Marginal fringe very short, 0.08–0.15 times as long as width of disc. Basal cell with 19–28 setae, costal cell distally with (2–)3–4 setae. Submarginal vein with six to seven setae, marginal vein anteriorly with 7–10 setae. Tarsal formula 5-5-5. Apical spur of midtibia distinctly setose, longer than half the length of the corresponding basitarsus (0.67– 0.74). Midtibial basitarsus ventrally with rows of distinct pegs. Tergites laterally with the following numbers of setae: T1: (0–)1, T2: 2, T3: 2, T4: 2–3, T5: 3–4(–6), T6: 3, T7 with four setae. Ovipositor longer than midtibia (1.12–1.35) and 2.20–2.52 times as long as clava. Third valvula 0.20–0.34 times as long as second valvifer.

Male. Colour similar to female except brown markings of mesosoma darker and more extensive. Gaster dark brown. Antenna with six flagellomeres, apical two segments partly fused and sensilla partly overlapping. Flagellar segments with abundant longitudinal sensilla.

Species group placement. E. strenua group.

Distribution. Australia: Queensland, South Australia, Western Australia.

Host. Aleyrodidae : Aleuroclava sp. , Synaleurodicus hakeae (Solomon) .
