The microspheric and megalospheric generations of the type genus Bolkarina have a large, thin and undulating lenticular test. The spheric microsphere and megalosphere are followed by numerous small arcuate chambers arranged in a planispiral-involute pattern. The thin septa have characteritically bifurcate intraseptal canals. later adult chambers with subrectangular-poligonal chamberlets are arranged in an annular mode; the connections of between adjacent chamberlets are provided by annular and radial stolons. The broad lateral chambers appear at the both sides of the test of the two generations. Also, the pillars and radial canals (funnels) are developed at the both sides of early stage of two generations. Selandian-early Thanetian.
