Identification
Members of Compsocerini can be distinguished from the superficially similar Trachyderini by tribal-level characters; identification within the tribe requires examination of antennal scape shape, elytral surface texture, and other morphological details. For example, in the Aglaoschema, species are distinguished by whether the antennal scape is subcylindrical versus , and whether are smooth or roughened (asperate).
