Wisshak, 2017

Emended diagnosis. Rosetted boring system, developed closely parallel to surface of calcareous skeletal substrates, with a circular to irregular outline, originating from a single point at the end of a tubular inlet tunnel. Individual galleries vary in width at constant height, ramify and may anastomose or fuse to form a flat central cavity. Fine galleries connect the rosette with the substrate surface, preferentially towards the rounded distal terminations.
