Description(s)
Wisshak, 2017:
Diagnosis. Entry tunnel straight or arched, leading to a mainly dichotomously and rarely trichotomously ramifying plexus of prostrate tunnels. Increase in tunnel diameter and lateral widening at branching points or terminations towards the periphery of the trace. Converging tunnels fuse to form anastomoses or evade and develop deeper tiers.
