C. cordicollis Chaudoir, 1835 forms a homogeneous group of high-mountain elements endemic to the Western Alps with C. angulicollis Sella, 1874 , and C. grajus K. Daniel and J. Daniel, 1898 . They each have a very similar structure of the aedeagus. The greatest affinities appear between C. cordicollis and its southern vicariant, C. grajus .
