Then you should almost have them all now. The Near Harad Oasis is a rather exceptional case as it's not shown on the map because it's generation is dealt with in a specific manner. All other sub-biomes generate either via map input and have a hex cide you can get from the map, or as biome variant, in which case they are neither defined as sub-biome nor shown on the map.

Only other exceptional case I can think of right now is the Tauredain Clearing, which is a sub-biome, but not generated via map input.
