Taksoni kirjeldused
Robinson & Lee, 2008
Diagnosis. – A more or less compact group of circular holes in hard calcareous substrates. The smaller holes at the centre of the group are more or less perpendicular to the surface; the more peripheral holes are typically larger, entering the substrate obliquely or centrifugally. The larger holes are often widely spaced. The diameter of the holes is up to ca.200 μm. The shell surface between the holes is largely undisturbed.
