Determined by Dr. Peter W. Messer, who said: “Discoderus sp. based on imaged pronotum sufficiently rotund/convex AND protibiae sufficiently plurispinose along distal half of outer margins. I don’t wish to go beyond genus with images alone for this tricky group.”

Found over 20 of these beetles under cinder blocks, which were lying on the ground
