Opinions on the correct taxonomic placement for the rail-babbler have differed. At one time, it was placed in the Old World babbler family, Timaliidae. Until recently, it had been regarded as being related to a group which included the quail-thrushes and whipbirds, and placed in the family Cinclosomatidae (previously in Orthonychidae when the members of the Cinclosomatidae were regarded as belonging with the logrunners). That relationship meant that the blue jewel-babbler of New Guinea was placed in the genus "Eupetes" until 1940, before being moved to "Ptilorrhoa".
