Metallic green to blue head and pronotum, often with some red lacunae on the pronotum; elytra yellowish medially with red margins that may sometimes extend over most of the area; ventral side mostly pale.
The locations of recent records of this species have been supressed for conservation reasons. It was 'rediscovered' on a field trip that I did with A.M. Sundholm in 2010, over forty years since the last known record in SA.
In 2021, after 23 years of collecting there, R.V. Glatz made the first collection of the species from Kangaroo Island.
Adults that I found on Dryland Tea-tree Melaleuca lanceolata appeared to have only recently emerged. This, taken together with known host relationships of related species and the habitats in which T. congener occurs, points to M. lanceolata as a probable larval host plant.
Tepper, 1887 reported that 'it feeds on the nectar of the flowers of Bursaria spinosa, on which I took them near Callington and Yorke's Peninsula.'
