| Abstract: | Hoeverellakrauseae gen. et sp. nov. is a peculiar runner-like anascan cheilostome bryozoan known from a single well-preserved specimen encrusting a belemnite guard. The colony comprises about 60 zooids, each of fusiform/pyriform shape and having a small “opesia” within which is situated an enigmatic ring structure. Several interpretations are possible for the ring structure: “regeneration”, closure plate, foreign organism inhabiting the zooecium, or socket of articulation for an erect branch or anAetea- like erect distal tube. Unusually for a runner-like bryozoan only one branch ramification occurs in the entire colony. The systematic position ofHoeverella is uncertain; however, it may be related to the electrid genusHerpetopora. |
