The original description was based on both sexes taken in New South Wales “in spirally curled leaf galls on Melaleuca sp. ”. However, Mound (2008) pointed out that this plant was probably misidentified, as minor has been found widespread between Canberra and Brisbane inducing rolled leaves on Callistemon saligna . This is one of the species with only two sense cones on antennal segment IV. It has the setae on tergite IX unusually small, and has the postocular setae variable and sometimes scarcely larger than the minor setae on the head ( Fig. 84 ). Antennal segments III–VI are largely yellow ( Fig. 86 ), and larger individuals of both sexes have a small tubercle at the inner apex of the fore tibia. Specimens studied in ANIC : Syntypes female and male, New South Wales , Port Macquarie, 3.ii.1900 .
