This flightless species was a medium-large rail that was described from bones discovered at Barber's Point, Oahu. Fossils of this species were also found at the Kuliouou rock shelter and at Ulupau Head, Oahu. It was named after C.J. Ralph and Carol Pearson Ralph who assisted Storrs Olson and Helen James in their research. This was the largest rail species known so far from the Hawaiian islands except for the also extinct Porzana severnsi.
