Breviceps

Brevicep, commonly known as rain frogs or short-headed frogs, consists of 20 species which most occur in arid to semiarid climates of Eastern and Southern Africa. Species of the genus Breviceps are sexually dimorphic: males are much smaller than females. This prevents normal amplexus; instead, males and females produce an adhesive secretion from the skin that allows them to "stick" together during mating For more information, visit the Wikipedia entry Get back to Anura
