Another related IAU Titan press release and a RADAR image mosaic I have not seen before..

"The new image released by JPL accompanying this release shows what appears to be a dried-out lake at Titan's south pole. Lopes thinks that the hydrocarbons there likely evaporated because this hemisphere is experiencing summer. When the seasons change in several years and summer returns to the northern latitudes, the lakes so common there may evaporate and end up pooling in the south."

There are a lot of carved canyonland landscapes down there.

Odd that some seem to be associated with bright blobby terrain. (Like at Hotei Arcus).

I'm wondering if there is a really big dried out basin occupying the southern mid to high latitudes, kind of a Greater Mezzoramia. At the end of T55 and T56 and at the end of T58 and T59.
(I don't think ISS dark correlates with a dried out basin.)

If so it would (could become?) be bigger than Kraken Mare.

Would agree Mike that Mezzoramia Basin might become a large lake at some point in the late S pole winter. VP has suggested that as well. I would imagine it couldn't fill in one season however and might be only a large playa much of the time. I'd offer the SAR data from T7, T39 and T39H as partially revealing the shoreline of such a lake draped over 70 S latitude between 330 and 30 longitude as shown below.
