Very cool Mark. Do you have import information? If you prefer, shoot me a PM.
I have two breeding groups of fine-spot dark orange-red bastimentos that were imported in 2004 without locality data that have bred true for two generations. Obviously, without definitive locality information I will not label them as red frog beach frogs - but their appearance and the reliability of color and pattern from two generations of offspring are interesting.
Depending on the detail of your import info, I might be interested in getting a group at some point to mix with the offspring from my groups [i.e. I wouldn't want to mix my 'suspected' RFB bastis with yours if they are definitive]
Here are some representative pictures.
