Remarks

• Systematics: Adult females of T. tripocula can be recognised by possessing a dorsal shield composed of sclerotic nodules separated by deep fissures and having a deep invagination at the posteromedial margin of each thoracic segment. Also distinctive are 1) the manner in which the posterior abdominal segments are directed dorsally in mature females; 2) the shape of the anal opening which is an irregular slit in a rugose sclerotic plate; and 3) the complete absence of tubular ducts. (Hardy & Gullan, 2010)
• Structure: Female gall on leaf, circular, almost level with leaf surface on orifice side, a slightly raised bump on opposite leaf surface; opening round to elongate, surrounded by raised ring of tissue, usually opening on adaxial surface of leaf. Gall tissue green but highly glaucous due to white waxy exudation on Eucalyptus cephalocarpa; gall not glaucous and becoming brown with age on E. aromophloia. Male gall on leaf, usually opening on adaxial surface. Similar to galls of females, gall surface glaucous if on E. cephalocarpa but gall tissue red, appearing purplish due to white wax covering. (Hardy & Gullan, 2010)
• Biology: Adult males emerged head first from gall openings, which was plugged by the male's first instar exuviae until gall maturity. The males were capable of short jumps of 1-3 cm either forwards or backwards, as well as weak flight. Adult females also may bear their fir-instar exuviae on their dorsum. (Hardy & Gullan, 2010)
