Glyphoglossus flavus is a species of frog in the family Microhylidae.[2][3][4] It is endemic to Borneo and is known from the Gunung Mulu National Park in Sarawak (Malaysia), Danum Valley Conservation Area in Sabah (Malaysia), and Ulu Temburong National Park in Brunei.[1] Common names Borneo squat frog[2] and yellow burrowing frog have been coined for it.[4]
Its natural habitats are tropical swamp forests. This burrowing frog is difficult to find and is expected to be more widely distributed than currently known.[1]
