Some authors later suggested that it belonged to family Formicariidae, the antthrushes. A study published in 1968 placed the genus in its current family, but there is still uncertainty about where it belongs. The ringed antpipit shares genus Corythopis with the southern antpipit (C. delalandi). They are treated as a superspecies and have been suggested to be conspecific. The ringed antpipit has three subspecies, the nominate C. t. torquatus (Tschudi, 1844), C. t. sarayacuensis (Chubb, 1918), and C. t. anthoides (Pucheran, 1855). == Description == The ringed antpipit is 13.5 to 14 cm (5.3 to 5.5 in) long and weighs 15 to 18 g (0.53 to 0.63 oz).
