Abstract
A new agelacrinitid edrioasteroid, Sumrallia rseiberti gen. et sp. nov., is introduced. Its morphology, with respect to different ontogentic stages, is described and figured, and its systematic position is discussed. Furthermore, synecological interactions of this edrioasteroid with brachiopods, bryozoans, and auloporid corals are documented. The new taxon supplements the highly diverse and extraordinarily well-preserved edrioasteroid fauna from the Holzbach Valley at Seifen in the Westerwald (Siegenian, Rhenish Slate Mountains).
Kurzfassung
Ein neuer agelacrinitider Edrioasteroid, Sumrallia rseiberti gen. et sp. nov., wird vorgestellt. Seine Morphologie wird unter Berücksichtigung unterschiedlicher ontogenetischer Stadien beschrieben und abgebildet, sowie seine systematische Stellung diskutiert. Darüber hinaus werden synökologische Interaktionen dieser Edrioasteroideen mit Brachiopoden, Bryozoen und Korallen dokumentiert. Das neue Taxon ergänzt die hoch diverse und außergewöhnlich gut erhaltene Edrioasteroideen-Fauna aus dem Holzbach-Tal bei Seifen im Westerwald (Siegenium, Rheinisches Schiefer-Gebirge).
