Dendrocharis flavicornis
Dendrocharis flavicornis is a species of false click beetle in the family Eucnemidae. It was previously classified under the genus Brachyelatus, and sources using that older name have described it as displaying brilliant blue and green metallic coloration. The species has been recorded from Australia. Fossil specimens attributed to this lineage, dating from 34–55 million years ago, represent the first known fossil record for the chalcid wasp subfamily Chrysolampinae—though this fossil assignment appears to reflect the earlier, incorrect wasp classification rather than the current coleopteran placement.
