Summary.

A new brachiopod, Arzonella exotica n. g. n. sp., from the Liassic (Broccatello) of Arzo in the Southern Alps of Switzerland was described. By the associated rhynchonellid brachiopod Sulcirostra alpina the stratigraphical stage could be specified as Sinemurian. Arzonella exotica is an unusual, probably conservative form. Its systematic position is not established yet. Possible relationships were discussed.

Zusammenfassung.

Ein neuer Brachiopode, Arzonella exotica n. g. n. sp., aus dem Lias (Broccatello) von Arzo in den Südalpen der Schweiz wurde beschrieben. Durch den assoziierten rhynchonelliden Brachiopoden Sulcirostra alpina konnte die stratigraphische Stufe als Sinemurian präzisiert werden. Arzonella exotica ist eine ungewöhnliche, wahrscheinlich konservative Form. Die systematische Position ist noch nicht geklärt. Mögliche Beziehungen wurden diskutiert.
