Blefuscuiana daminiae

Taxonomy

Original description: Characterised by having 5 chambers in the last whorl of which only part of the first is seen ventrally, thereby giving an overall subquadrangular appearance to the test and by a deep umbilicus, resulting from the distinct overhang of the chambers in the last whorl. Adult test about 0.20mm at its maximum diameter, comprising at least 2 whorls coiled in a low trochospire. There are 5 chambers in each of the penultimate and last whorls. The spiral side is slightly concave to slightly convex and the intercameral sutures are moderately depressed, forming intercameral angles of about 140-150 degrees at the periphery of the test. The chambers are symmetrical and increase gradually in size with growth. They are subglobular in the penultimate whorl and depressed to slightly depressed (about 1/2 - 2/3 as high as long, when viewed from the spiral side) in the last tum of the spire, with the first two chambers in the latter tending to be more depressed than the last three. The final chamber may be almost as high as long. The umbilicus is small and deep; the aperture appears to be a narrow slit.
