Entobia nana Wisshak, 2008

Diagnosis: Very small ichnospecies with irregular, potato-sack-shaped cavities oriented parallel to the substrate surface, often bearing few to many apophyses and exploratory threads that terminate bluntly or lead to neighbouring chambers. The traces show a bulged to weakly cuspate (in casts weakly botryoidal) microsculpture.

Differential diagnosis: This ichnospecies is distinguished from all other Entobia ichnospecies by its much smaller dimension and the lack of a pronounced botryoidal surface texture
