Descriptions and remarks
Diagnosis: Borings with 1.1−2.2 mm total depth range, 0.7−2.8 mm chamber diameter range and 0.3−1.3 mm aperture width range. The aperture neck is wide relative to the chamber diameter, forming a column slightly narrower than the chamber diameter and leading into the wider main chamber. Thin, filamentous branches are distinct from this central chamber, radiating from its base into the surrounding bone.
