In Austria there are three almost identical species.

On the male species it is relatively easy to identify C. cuprea. The lamella of third segment of the pectinated antennas is very short, like a stub.

On C. pectinicornis the lamella on the third segment is about the same length as the segment.

On C. heyeri the lamella on the third segment is longer than the segment itself.

According to this one rule, this species should be the C. pectinicornis, but it is not 100% certain.
