A buddy of mine is looking after the female 'salvias'. I have not been able to find a mate or even another 'salvias' in over three years now! I have contacted Sean a bunch of times and he has never had 'salvias' when I have asked. I did get 'santa isabels' from him - which were amazing. Unfortunately I sold those off. I just recently emailed Jon Werner and like you said he is working with frogs that don't have the flash marks.
I was trying to sell the female 'salvias' since I have had zero luck finding a mate for her, but nothing came of it, so I sent her off with some frogs and geckos to a buddy. Hopefully, I can find some others and get the female back and form a colony.
Tor Linbo has 'salvias' frog info on his web site. He sent out a price list prior to Frog Day, but did not have 'salvias' on it.
