They are a variant of coronata, I have a few and Marcia has some too!
most exporters think they are lepidogaster, this is why keepers refer to them as such.

Lepidogaster; have eye patch, shoulder bar, are sexually color dimorphic, rough belly scales.
Coronata; has little or no eye patch, no shoulder bar, no sexual color dimorphism, less rough belly scales.

similarities;
both species have blue mouth and are of similar body size.

Thanks for the come back, I understand.
