I have a book, <u>Amphibians The World of Frogs, Toads and Newts</u> edited Robert Hofrichter (excelent book with an index of every amphibian species known by 2001, including chengongensis), says that this process that produces triploid individuals, also known as gygogenesis happens in mole salamanders. A similar process exibited by edible frogs is Hybridogenesis which produces diploid individuals of either sex. Both gygogenesis and hybridogenesis, are examples of parthenogenesis, were sperm is merely an activator of cell division, or doesn't participate at all.
