In past, often treated as conspecific with R. longirostris, R. tenuirostris, R. obsoletus and R. crepitans, or with R. tenuirostris and R. obsoletus; more recently only with R. tenuirostris; but recent study#R indicates that each of these taxa merits recognition as a separate species, based largely on molecular evidence supported by morphological details, with present species “rufous-breasted,… relatively large” and breeding in freshwater marshes; the differences are complex and require detailed evaluation both between and within current new species limits, but are provisionally accepted here in the light of genetic findings. Two subspecies recognized.
