Castiarina skusei  Distinctive features

Easily recognisable by the inverted 'T'-shaped dark markings on the elytra.


An outlier from eastern Australia only found in SA on Kangaroo Island. The SA forms do not show any obvious consistent differences, but tend to be more heavily marked. Barker 2006a noted that there were yellow and brown forms (elytral background colour) and that these were independent of sex.
