This is not D. leucosticta. It isn’t possible to identify this species more accurately without having the specimen under a microscope. Its size is greater than cupripennis and I don’t think marmorata (which is the right size range) has a bright green pronotum. I will check my reference collection in a few days and see.
Thanks. Some marmorata on ALA seem to have bright green - there seems to be an informed commentary under https://www.inaturalist.org/observations/66457490 (linked from ALA) but outside my knowledge.
