Taxonomic Notes
The Onichodon contains few described and is considered taxonomically challenging. The Eucnemidae (false click beetles) was historically treated as a of Elateridae but is now recognized as a distinct family based on morphological and molecular evidence. The inability to produce an audible clicking mechanism (lacking the prosternal process that engages with the mesosternal cavity) is a key diagnostic feature separating Eucnemidae from Elateridae.
