Description
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.[1] Genetic evidence has indicated that Pachyplichas is nested within Xenicus, and stout legged wrens must have evolved from a gracile legged ancestor. A cladogram is given below.[2]
