Identification
1/9/2017: I removed my provisional key to North American Discoderus (last version 2/07/2015b) at both BugGuide & ResearchGate because I felt it was misleading with too many problems in its current state. A better identification key will be developed in conjunction with plans to survey Discoderus species across the United States. - Peter W. Messer
