Schulz (1866-1933) who had collected the type specimen. Various authors have misspelled the specific epithet as schulzi and schultzi. Of the five species now placed in the genus, a molecular genetic study has shown that the rufous-throated dipper is most closely related to the other South American species, the white-capped dipper (Cinclus leucocephalus).
