Relationships uncertain within the complex containing C. conradii, C. torquata, C. eisenmanni and present species (also relationship to C. prunellei and C. wilsoni); further studies needed (see also C. torquata). Present species traditionally considered conspecific with C. torquata (which see). Race omissa doubtfully valid, as the characters distinguished are very weak and not constant. Two subspecies currently recognized.
