Berlepsch and Stolzmann, 1892,
Chorillos, near Lima, Peru.
See C. patagonicus. Arguably conspecific with C. nigrofumosus, but differs in its white-streaked brown vs (dark-stippled) white chin and throat (3); much weaker white streaking below (2); paler brown plumage above and below (1); and somewhat smaller size (sample size small; but at least 1). Study of conditions where the two taxa approach each other geographically would be of interest. Monotypic.
Coast of C & S Peru (Ancash S to Tacna).
