Cephalis and thorax sparsely perforate, covered with layer of microgranular silica. Abdomen and all post-abdominal chambers comprised of then, longitudinal costae superimposed on each row of pore frames. About nine to ten costae visible laterally. Pore frames medium in size. Chambers increasing gradually in width as added with final post-abdominal chamber remain ing in the same width or decreasing slightly in width.
Original remarks: Drulanta mostleri, n. sp., differs from D. mirifica, n. sp., by having a shorter with smaller cephalis.
