Kaloula rugifera, the Sichuan digging frog or Szechwan narrowmouth toad, is a species of frog in the family Microhylidae found in China.
It is endemic to China where it is found in Sichuan and extreme southern Gansu.[1]
Its habitats are hilly areas near villages. It has also been recorded from tree-holes. Breeding takes place in temporary pools and ponds. This previously very common is believed to be declining because of habitat loss associated with infrastructure development.
Male Kaloula rugifera grow to a snout–vent length of about 39mm and females to 49mm. Tadpoles are up to 31mm in length.[2]
