I think you got it.
Here's a link to the history of the salmon boas established by Rich Ihle:
http://www.salmonboa.com/about.html
Then there are the orange tail hypos established by Jeff Gee.
Now Jeff Ronne, Boaphile, has established what is thought to be a pure Columbian hypo, very pretty, I don't know much about them to speculate.
As far as I know, all the lines are compatible (I know salmon and O.T are) and lots of the hypos out there are mixes or just can't be traced directly back to where it started from. I have 1 salmon that was from a Rich Ihle F2 male, all the other hypos in my collection are just called hypos. Except for any pure Columbian hypo lines, they are all locality mixes of Columbian x Panama boas from my understanding.
Hope that helped a bit.
They are my favorite boa morph hands down
