Burmese Python is another famous Python species found in Himalayan and North-east region of India and several other South-east Asian countries. For a long time it was considered as subspecies of Indian Rock Python (P. molurus) but now placed as separate species. Morphologically both species looks same in size and patterns. However these two species does not overlaps in greater part of their geographical distribution. Both species can be differentiated mainly by checking side blotches which are larger and definable in former and much smaller in P. molurus. In scalation these two can be differentiated by checking subocular which is found in P. bivittatus and clearly excludes supralabial from eyes while in P. molurus supralabial remain in contact with eyes.
