A scarab beetle, probably a Christmas beetle (Anoplognathus). A hint about how long it was would be useful as the background doesn't give much of a clue about scale. To identify Christmas beetles to species you need a good look at their backside - red? green? straw-coloured? hairy or not?

Resembles a Christmas beetle (subfamily Rutelinae), but belongs to Dynastinae. An important distinguishing feature between the two subfamilies is in each tarsus: Rutelinae have the two claws unequal in size and individually movable, whereas Dynastinae have them equal and more or less fixed together.
In the Argentinian scarab, the long, thin tarsi are also distinctive; Christmas beetles have shorter, thicker tarsi and larger claws, needed to hang on to foliage in all weather conditions.
