Hasselt's Spadefoot Toad

Hasselt's toad, also called the Java spadefoot toad or Hasselt's litter frog, is a toad found in Southeast Asia, named after the Dutch naturalist Johan Conrad van Hasselt. According to the current understanding it is known with certainty only from Java, Madura, Bali and the Kangean Islands, Indonesia, so its Sumatran and Malaysian listings should be checked (Wikipedia, general species account).
