I am not familiar with the species, but with many species (especially those with the word "burrowing" in their name as they normally come from areas with a definite dry and wet season, a brumation period is required. The frogs should be cooled and brumated for a month or two in drier, cooler than normal conditions to simulate a dormant period. After the period is over, the frogs should be misted heavily and the temperatures should be raised. Rain chambers can then be used after heavy feeding to stimulate the frogs to breed. As I said, this is with some frogs and hopefully someone can provide some more insight. Good luck and let us know if you find anything more outside of the forum.
