Taxonomy
The stout-legged wrens formed a species pair. They had reduced wings and robust legs indicating that they were adapted to a terrestrial existence and were either flightless or nearly so.[2] Genetic evidence has indicated that the former genus Pachyplichas is nested within Xenicus, and stout-legged wrens must have evolved from a gracile-legged ancestor. A cladogram is given below.[3]
