It was known as the medium-large Oahu rail or medium flightless rail until its formal description,[3] to distinguish it from the other flightless rail species which was endemic on Oʻahu until after the arrival of humans. Traditionally placed in the "wastebin genus" Porzana, it almost certainly does not belong there, and its place in the rail family is effectively unknown as of 2023.[4] Its scientific name honour C. John and Carol Pearson Ralph, who provided housing and other support for the scientists who found and described the species.[1]
