Large Tumbling Flower Beetle (Hoshihananomia sp.)

A large Mordellid beetle about 15 mm long. It had the typical wedge shaped body with humped thorax and a pointy rear end (pygidium) which extended well past the elytra. The thorax and wings were covered with fine hairs giving it a glossy look and had symmetrically placed cream spots and patches. A dome shaped head had a felty cover and laterally placed eyes. It was attached to the thorax by a very narrow neck and the beetle could completely flex the head under the thorax to protect it. I also observed it turning the head to an almost 90 deg angle to the body.
Antennae were saw-toothed. Hind legs were larger than the others.
Spotted on a tea-tree in a reserve. This beetle was in the company of many other Mordellids but all of varying sizes.
