Dear Zeineb,

Thanks for another record of this yellow species, or group of species, with large black spots. As I mention in another message, I am not sure if all the animals I am tentatively placing with P. polkadotsa are the same species. Only time, and more records and more studies, will solve the problem

Best wishes,
Bill Rudman
