Planation surface
The processes that form planation surfaces are labelled collectively planation and are exogenic (chiefly erosion). Etchplains are weathered planation surfaces.
Large planation surfaces, like the African Surface, are typically formed diachronously.

Peneplain
The last is the case of planation surfaces that may be peneplains or not, while some peneplains are not planation surfaces. In their 2013 work Green, Lidmar-Bergström and co-workers provide the following classification scheme for peneplains:
Planation surfaces
Pediplain

Mapping of planation surfaces in the southwest region of Hubei Province ...
Planation surfaces (PS) play a major role in reconstruction of the evolutionary history of landforms in local areas. Thus, objective and consistent mapping of planation surfaces from remotely sensed data (e.g., satellite imagery, digital elevation models (DEMs)) is paramount for interpreting the geomorphological evolution. Due to the lack of dated sedimentary covers and the difficulties of ...

Crick did also coin the term panplanation to describe a planation surfaces thought to be formed by lateral stream migration.
