White-barred piculet northeastern Brazil; "P. c. thamnophiloides" found in southeastern Bolivia and northeastern Argentina; "P. c. tucumanus" found in northwestern Argentina; the Pilcomayo piculet, "P. c. pilcomayensis" found in southeastern Bolivia, Paraguay and northeastern Argentina; and the nominate subspecies "P. c. cirratus" found in southeastern Brazil, southern Mato Grosso and eastern Paraguay. The taxonomy of this species is difficult; the races "pilcomayensis", "thamnophiloides" and "tucumanus" intergrade in northern Argentina and are sometimes considered a separate species, and "pilcomayensis" intergrades with "cirratus" in eastern Paraguay. The northern subspecies, "confusus" and "macconnelli" may also be a distinct species. The white-barred piculet also hybridizes widely
