Description
Female. Colour: head yellow, mesosoma pale, pronotum partly, anterior margin of mesoscutal midlobe brown. Gaster mostly pale, petiole and T1 anteriorly slightly darkened, T2–T4 slightly brown laterally and T5 and T6 with indistinct brown band. Third valvula brown, lighter at base than at apex. Antenna yellow. Fore wing hyaline. Legs yellow.
Morphology [measurements of holotype in square brackets]: stemmaticum with transversely strigose surface sculpture. Antennal formula 1,1,3,3. Pedicel longer than F1 (1.50–1.78) [1.71]. F1 subquadrate or slightly longer than its maximum width (1.00–1.14) [1.14], shorter than F2 (0.54–0.62) [0.54] and F3 (0.56–0.62) [0.56]. F2 subequal in length to F3. Flagellomeres with the following numbers of sensilla: F1: 0, F2: 2, F3: 2–3, F4: 3, F5: 3, F6: 3. Midlobe of mesoscutum with 8–10 setae, arranged symmetrically, side lobes with three setae each. Scutellar sensilla very distantly placed (approximately eight to nine times the maximum width of a sensillum). Distance between anterior pair of scutellar setae subequal to distance between posterior pair. Fore wing 2.2 times as long as width of disc. Marginal fringe 0.19–0.23 [0.19] times as long as width of disc. Submarginal vein with two setae, marginal vein anteriorly with six to seven setae. Basal cell with four to six setae. Tarsal formula 5-5-5. Apical spur of midtibia almost as long as or subequal in length to corresponding basitarsus (0.88–0.94). Tergites laterally with the following numbers of setae: T1: 0, T2: 1, T3: 1, T4: 1, T5: 2, T6: 3, T7 with four or five setae. Ovipositor subequal in length to midtibia and 1.68–1.80 [1.80] times as long as clava. Third valvula 0.47–0.54 [0.54] times as long as second valvifer, apex of third valvulae truncate.
Male. Unknown.
Species group placement. E. lutea group.
Distribution. Australia: Western Australia.
Host. Aleyrodidae .
Material examined
Western Australia: Holotype: ♀, Lake Argyle, 4 May 2000 (S. and O. Schmidt), ex whitefly on Eucalyptus sp. (Myrtaceae) (ANIC). Paratypes: 2♀, same data as holotype (ANIC, ZSMG) and 2♀, Purnululu National Park, 4 May 2000 (S. and O. Schmidt, J. Martin) (ANIC, ZSMG).
Comments
The species is similar to E. hamata (Huang and Polaszek) and E. udaipuriensis (Shafee) , but has a longer ovipositor which is subequal in length to the middle tibia, but shorter in hamata and udaipuriensis . From udaipuriensis it differs also in not having a longitudinal sensillum on F1 and a shorter third valvula (0.65 times as long as the second valvifer in udaipuriensis ). From hamata it differs by the symmetrical apices of the third valvulae (asymmetrical in hamata ) and a less extensive brown colour.
