Thanks. Until I asked the question, I had forgotten to check with The Gesneriad Society of which I'm a member. They are the International Registration Authority (except for Saintpaulia). For anyone else who is interested I did find that most of the old genus of Chirita is now going into the genus Primulina. A few are not. Those are a little all over the map at the moment but the majority of Chiritias are there.
Thanks for answering.
