Ansonia latidisca, commonly called the Sambas stream toad or Bornean rainbow toad, is a small true toad rediscovered in 2011 after being unseen since 1924. It is endemic to Borneo (Indonesia and Malaysia). Its natural habitats are tropical moist lowland forests and rivers. It is threatened by habitat loss.
The three specimens known of A. latidasca are small, ranging in size from 30 to 50 mm (1.2 to 2.0 in) in length. They are also nocturnal. They have long spindly limbs and variegated dorsal skin "splattered in bright green, purple, and red." The colorful spots on the dorsum are not flat but "pebbly" and have been compared to warts. Amphibian expert Robin Moore told the National Geographic that such skin on a toad "usually indicates the presence of poison glands... You probably don't want to put this in your mouth." Moore was the initiator of Conservation International's Search for Lost Frogs.
Herpetologist Indraneil Das, leader of the 2011 team that rediscovered the toad, called its coloration "mosslike" and noted that it may be an adaptation for camouflage on the mossy tree bark of its habitat.
