Whitish sub-appressed hairs on frons; widespread grey-purple or grey-violet colouration, especially on the pronotum, combined with areas of green to blue reflections.
A diverse array of specimens with much variation in size and colouration have been referred to this name in Australian museums, and there may be more than one species involved. Specimens from the Adelaide area tend to be smaller and less colourful than those from elsewhere in SA.
The type on which MacLeay 1872 based his description was from Gayndah in the SE part of Queensland. He describes the general appearance as black, the forehead (frons) as being 'clothed with white pubescence', the thorax (pronotum) purple, the underside as brassy and subnitid (not strongly shiny), and gives the length as 2.75 lines (c. 5.8 mm).
| Legend | |
| number of active beetles, actually recorded in that quarter-month |
| estimate of active beetles, inferred* from adjoining date ranges |
| actual count > 2 (median) |
| actual count <= 2 (median) |
| inferred* active beetles only (mostly from colour lure trap results) |
| live non-emerged (inactive) beetles only |
| | *Inferred when a site has counts of active beetles for each of two consecutive
periods (date ranges), one finishing and the other starting in the same
quarter-month.
The count estimate is assigned to that quarter-month and calculated
as the lower of the two total beetle counts, divided by the number of quarter-months
in its date range.
Assumes that beetle activity is essentially continuous within a single active period per year, and that date ranges do not bridge a non-active period (thus only ranges of < 4 months are used). |

I reared three adults of this species from prepupal larvae extracted by A.M.P. Stolarski from stems of a dead Eucalyptus leptophylla (Narrow-leaf Mallee). These are the first breeding records reported for the species.
