A new species Conochitina rugata, earlier treated as nomen nudum, is formally defined. The species has been identified in the upper part of the Pirgu Stage in many East Baltic sections of the Baltica palaeocontinent, and in two regions of the Avalonia palaeocontinent. It has not been found in Scandinavian and Polish sections due to gaps or barren redbeds.
