Previously considered conspecific with C. curtata by some authors, but recent genetic analysis#R shows present species to be sister to a group consisting of C. semicinerea, C. hellmayri and C. subcristata. Race cardonaorum originally spelt cardonai, but internal information (“...a los Ingenieros Jordi y Heinz Cardona...”) requires emendation. Two subspecies recognized.
