Brachiophore bases slightly inclined medially to form a flattened or slightly concave septalium merged laterally with fulcral plates forming a platelike structure projected ventrally following the same plane of the interarea. Cardinal process absent or represented by a faint ridge. Dorsal median septum proximally supporting the septalium.
