Systematics: Adult females of T. maculata are very similar to those of T. maskelli. T. maskelli can be distinguished by the much smaller eyes, the distinct marginal fringe of setae, and the longer dorsal setae on the abdomen and along the margin.
Structure: Female gall is dull green to brown, has a pyriform brown cap. Immature galls much more elongate, flask-shaped, variable. First-instar females pale pink to salmon in color, filling up the cavity in mature galls at the apical opening. Eyes black, body elongate-oval. First-stage female yellow, flat on upper side, elongate, rounded at the top. Second-stage female bluish gray, covered with whitish dust on the back. (Froggatt, 1894b) On stem, conical to thorn-like. Gall opening found to oblong. Base of gall broad, surface rugose, distal portion attenuated and annulated. (Hardy & Gullan, 2010) Male galls are reddish-brown, broad at base and tapering towards the tip. Adult male is reddish-pink, dorsal eyes large, black and globular (Froggatt, 1894b). On stem and either leaf surgace. Tubular, narrowing slightly towards apex. Gall opening indistinct to round. Gall thin-walled and cylindrical, distal edge surrounding opening crenlate. (Hardy & Gullan, 2010)
General Remarks: Detailed description and illustration of male and female galls, first-instar nymphs and adults (Froggatt, 1894b). Redescription, photograph of galls and illustration in Hardy & Gullan, 2010.
