Gumnut leaf beetle

Description:

A brown hemispherical beetle looking like a gumnut. The elytra are pitted and overall color is mottled browns.

Habitat:

On a large Red Box Gum in a habitat reserve.

Notes:

This is visually similar to Paropsisterna, a more colorful genus. The brown ones get tossed into the "thrachymela group" on the assumption that these are too hard to find a more specific taxon. It looks similar to Trachymela III from Brisbane insects http://www.brisbaneinsects.com/brisbane_...
