This image of Tethys shows us its three most notable features. Top left is the Odysseus impact basin - chief reason why, to my great shame, I often have difficulty distinguishing Tethys from Mimas.

Well, those Titans were a fractious bunch.

While both Tethys and Mimas have huge craters, you can clearly distinguish the two because Tethys is much larger and it's topography is more relaxed. Both regular impact craters and the two huge ones are more relaxed on Tethys. Herschel on Mimas is much deeper for instance.
