Pachyplichas
Pachyplichas is a genus containing two extinct species of New Zealand wren, a family of small birds endemic to New Zealand. Species
 †P. yaldwyni (South Island stout-legged wren) – South Island, New Zealand
 †P. jagmi (North Island stout-legged wren) – North Island, New Zealand

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. 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. References
