A new genus Perakella gen. nov. including two species: P. shakhtauensis sp. nov. from the Upper Asselian of Middle Cisuralia and P. batteni sp. nov. from the Middle Permian of Malaysia, is described. A unique find of this genus in the reef limestones of Shakhtau is further evidence of the presence of elements of Tethyan taxa in the Early Permian communities of the Uralian corridor.
