Lapispecus cuniculus Voight, 1970

Diagnosis: Main tunnel relatively constant in circular diameter, curled in partially tight windings close to the substrate surface or keeping close contact to earlier curls of its own tunnel. A thin vane may be developed between the tunnels on the concave side of windings and between the main tunnel and the substrate surface. Tunnels may cut through each other but more generally avoid breaking through into pre-existing tunnels or to the substrate surface
