I am recently getting back into snakes after a long break and purchased a couple of hatchling tricolors - they are incredible creatures and I am very excited to have them as pets!

I have a question --- apparently there are 3 species of tricolors that look identical? --- I have been trying to discern the physical difference between L. PULCHER, L. SEMICINCTUS, and L. MATOGROSSENSIS --- i looked at google images for some clarity on the subject and now I am totally confused....

Does anyone have a clue how each of these 3 species actually looks???

I would greatly appreciate links to pics with species noted - if anyone knows. Thanks!!!!
