Hi Alison, I finally got to this handsome little one. It's a Syarbis, in tribe Gonipterini, so (in our region) related to Gonipterus, Oxyops and Iptergonus. Syarbis are all small, and are distinguished by not having tarsal claws. The AFD lists 22 species in the genus, but there seems to be no images online of the majority.
