Buprestidae of South Australia
( Jewel beetles )
by Peter J. Lang
Astraeus mastersii   Macleay, 1872
subfamily  Polycestinae » tribe  Astraeini » subtribe  Astraeina
Notes

Known in SA from a specimen labelled as collected by W. White on 16 December 1869 from the Reed Beds (now Fulham, on the west side of Adelaide).

The habitat in this area has been greatly modified by changes to the water regime and suburban development. A number of plant and animal species previously recorded from the Reed Beds area are now considered to have become regionally extinct, and this may be another example. However, there is always the possibility of mixed labels or mis-labelling. Given that it is such an old collection, is a single specimen with no other supporting evidence, and represents such a major disjunction from the rest of the species distribution in eastern Australia, it is here flagged as questionable to indicate at least some degree of uncertainty.

A second SA occurrence is based on the trapping of a single individual on Calperum Station in MU region, reported in Pullen 1997 by Coleoptera expert J.F. Lawrence who was also credited with making the identifications.

Host plant notes

Casuarina appears to be a host genus for this species. The MU record of Lawrence 1997 was trapped in a drainage depression dominated by Black Oak (Casuarina pauper), and Barker 1975 cites 19 specimens collected on Casuarina equisetifolia at Endungalba in Queensland.
