The new species was found at a depth of &lt;60 m on the East coast of Korea. The test morphology is typical of the genus\n                    <jats:italic>Capsammina<\/jats:italic>\n                    , comprising two or more mica plates with a ring of finely agglutinated mineral grains sandwiched between them and surrounding the cell body. There is no distinct test aperture. Elemental analyses of the agglutinated grains revealed 15 different types of mineral grains of which quartz is the most abundant. The surface areas of grains exposed on fractured surfaces ranged from 1.6 to 7,700 \u03bcm\n                    <jats:sup>2<\/jats:sup>\n                    and the large plate-like grains forming the upper and lower surfaces measured about 420\u20132,350 \u03bcm in maximum width.
