Original Description
Test wall microperforate with randomly distributed pores, pore diameter ranging 0.6 to 0.8 microns, surface smooth or with weakly developed perforation cones. Test very small, coiled in a low to rarely moderate trochospire, equatorial periphery moderately lobate, equally biconvex, test thickness:diameter ratio averaging 0.55; chambers subgobular to globular, dextrally, or sinistrally coiled in a low trochospire consisting of 2 whorls of 8 to 9 chambers that increase rapidly in size, ultimate:penultimate ratio averaging 1.14, antepentultimate:ultimate ratio averaging 1.3, with 4.0 to 4.5 chambers in the final whorl, final chamber face extends in the direction of coiling; sutures moderately depressed, radial, straight; umbilicus shallow, narrow, umbilical: test diameter ratio averaging 1.4; aperture an extra-umbilical low arch that extends from near the peripheral margin into the umbilicus, without a bordering lip.
