First, excuse me for my English!
The Python m. pimbura is exclusively native of the Sri Lanka while the molurus molurus is native of West Pakistan, India, Nepal, south China and Bangladesh. The molurus bivittatus Thailand, Burma, Borneo.
Currently the pimbura is considered as a synonym or locality of the m. molurus.
Therefore also the "pimbura" is in CITES I.
To my opinion the definition of synonym is wrong in how much the molurus molurus and the pimbura are clearly different for morphology. For example the head of the molurus molurus is more lengthened and uniform while in the pimbura, it is visibly bigger to maxillary level.
The dimensions are different, the pimbura doesn't overcome the 3,5 meters while the m. molurus reaches the 5. The colors are different, the "pimbura" has the head with prevalence of red and rose and the lance it is very vanished. The molurus molurus has a prevalence of grey and brown.
Apparently they are animal completely different.
A comparison would be interesting to genetic level to understand if indeed they are two different subspecieses.
