Genetic analysis#R indicates that this species is closely related to C. pallida and C. pyrrhophia; apparently hybridizes with latter, and in past sometimes suggested as being conspecific, but very little evidence of introgression#R. Proposed race siemiradskii (Paraná, in Brazil) is indistinguishable. Monotypic.

Distribution:

E Paraguay, SE Brazil (S São Paulo S to S Rio Grande do Sul) and NE Argentina (Misiones, N Corrientes).
