Descriptions and remarks
Diagnosis: The tunnels are longitudinal, parallel to the xylic substrate, round and straight, without lining. They have a single, short entrance perpendicular to the main tunnel axis. The branching is slightly curved and parallel to the main tunnel. The main tunnels are interconnected by curved cross tunnels, which may take the form of chambers. In those tunnels single, elongated coprolites are present (Fig. 2F).
Ethological category: Domichnia (dwelling traces) or agrichnia (farming traces).
