Head and pronotum green to bronze; elytral background orange, fasciae dark with blue-green reflections and strongly angled outlines.
The 16 specimens of the type collections were originally assigned by Barker 1980 to C. bucolica (as Stigmodera (Castiarina) bucolica), a similar but somewhat smaller related species from WA.

The holotype specimen label has the word 'Baeckea'. It, and the 9 paratype specimens that were also collected on 16 Nov 1974, were taken from the 'flowers of Baeckea sp.' according to Barker 1986. This must refer to Hysterobaeckea behrii, since the only other southern Eyre Peninsula plant included in Baeckea at that time is Rinzea orientalis (formerly Baeckea crassifolia), an early-flowering species which would have finished flowering well before that date.
