Stethon can be distinguished from true () by the structure of the prosternal , which does not articulate with a corresponding mesosternal cavity to enable the mechanism. They lack the spring-loaded thoracic hinge that characterizes Elateridae. Within , specific identification requires examination of antennal structure, body proportions, and elytral sculpturing; species-level determination generally necessitates detailed morphological study.
