The species was first discovered in SA in November 2015 from WSW of Coomandook and is now known here by numerous records from mallee heath habitat in the northern part of the SE Region and extending into the extreme south of MU Region. Its presence on Eyre Peninsula (EP Region) was inferred from incomplete dead adult remains found in November 2022, and from matching larvae at a separate site in July 2023. It was found in the eastern Mt Lofty Ranges (SL Region) in September 2023. It seems likely to also occur in Victoria and possibly other eastern States.
B. Levey (pers. comm., Jul. 2020) considers that this may be M. ignicollis or something closely related to it.

The adult and larval host records of this species in the MU and SE Regions were discovered by A.M.P. Stolarski. They provide strong evidence for its regular breeding in Rough-leaf Common Correa (Correa reflexa var. scabridula).
More recently, I found incomplete dead remains of what appears to be the same species in a root crown of Small-leaf Microcybe (Microcybe multiflora) on Eyre Peninsula. This plant belongs to the same family as the Correa, Rutaceae. As the beetle identification was based largely on just a single elytron, it is regarded as tentative.
Two more recent records of larvae with prothoracic details matching those of the SE specimens were extracted from Salmon Correa (Correa pulchella) on EP and provide further support both for for its occurrence in this region and the host association with plant family Rutaceae.
In September 2023, A. Stolarski and I found evidence of it breeding in the SL region using a third Correa species, C. glabra var. turnbullii (Smooth Correa) as larval host.
