see text What is now the rufous antpitta complex was long considered to be a single species, Grallaria rufula, with seven subspecies.
[1] In 2021 the International Ornithological Committee and the Clements taxonomy implemented the split of the rufous antpitta into multiple species and accepted the newly described species.
The revised Grallaria rufula sensu stricto, now called the Muisca antpitta, has no subspecies and is thus monotypic according to those taxonomies.
[2][3] However, BirdLife International's Handbook of the Birds of the World (HBW) did not fully implement the split.
They include the former subspecies of the rufous antpitta, the newly described species, and two previously known species newly recognized as part of the complex.
