Hello Tim,
The breeder whom offered me the newts took over the batch of newts from another hobbyist. All I know is that these animals were first brought in by a dutchman named Frits van Leeuwen. The papers she had as I asked her were print-outs and documentation in dutch showing the species range but not exactly the location of where the first specimens were obtained. Species range of Yambaru and Tokashiki were indeed mentioned. These animals were first unknown but then were later identified by Ad Bouwman to be Cynops ensicauda popei.
My newts ( the adults) are adults from possibly different ranges. One of which could be Tokashiki and the other, Yambaru. Unless a genetic sampling is done, there is no way to be sure. My male candidate may have descended from the Tokashiki race.
The resulting juveniles have been so mixed in their parentage they are beginning to take a varied pattern and some even have developed patterns on their tails! (refer to the blur photo above). One of my juveniles has the orange colouration which extends to the tail! I'll post a clearer photograph soon.
