This flightless beetle has otherwise never been found east of the Mississippi River except for LeConte’s specimens. There have been multiple attempts to find the beetle in this area (

. The distinctive body form, elytral coloration with bronze and green reflections, prominent green subsutural foveae and complex surface texturing are diagnostic. Some individuals have a strong green-bronze sheen over all surfaces, and this trait appears to be more prevalent towards the eastern part of the species range.
