They were previously considered to be in the family Microhylidae, but genetic analyses suggest that they share a common ancestor and are more closely related to Hyperoliidae, Hemisotidae and Arthroleptidae.
Four genera are found in the Eastern Arc, including Breviceps, Probreviceps, Callulina, and Spelaeophryne. The latter two are endemic to the Eastern Arc Mountains of Tanzania. All have small narrow heads and short hind limbs. Males are typically much smaller than females and some species rely on a sticky substance produced by skin glands to glue themselves to females during mating. Females lay eggs in underground cavities and the eggs hatch directly into small frogs without a frees wimming tadpole phase (Text from Harper et al., 2010).
The family Brevicipitidae occurs only in eastern and southern sub-Saharan Africa.
