Stunning picture! Amazing colors!!

yes, that's one of the problems with insects, sometimes differences betwen species are very subtle, other times the same specie can have many different colorations and shapes (polimorphism)

very stylish !

I think they are 2 different species.

May be Synonym...

Good guess, Ashish. But if you look at the shield above the head you may notive that the black parts are separated in Mexicana in Cingulata not. And there are no white parts next to the body in Cingulata. In addition Cingulata seems to be a South American species. Membracis mexicana is safe in my eyes.
This one is from Colombia:
