Microcastalia scintillans  Distinctive features

Reddish-brown above and below with coppery reflections (the 'metallic scintillations' of Carter 1924b) in the puncta and elsewhere. Also differs from M. globithorax in the pronotum being more convex above and the elytra having more pronounced ribs with coarser puncta between them and the apices more acutely trispinose.

Notes

Previously placed in other genera by Carter, this Western Australian species was transferred to Microcastalia by Bellamy & Peterson 2000. It has only recently been recognised as occurring in SA (Lang & Stolarski 2020) and is known here by a series of dead specimens collected by P. Hudson from 1998 to 2006 in the strand deposit of an Eyre Peninsula salt lake. The first live specimen was collected on an Acacia branch 106 km NNE of this site in December 2008 by M. Hura and is illustrated above. It reveals that this species, when fresh, has the same white powdery excrescence in the puncta and other declivities as found on M. globithorax.

Host plant notes

The single live occurrence on an Acacia branch may be incidental and is regarded as inconclusive.
