Rodzaj Pandorinellina Müller & Müller, 1957

Gatunek typowy
Pandorina insita Stauffer, 1940 from the latest Givetian Lithograph City Formation of Minnesota 

Opis

P1 elements developing more or less expanded basal cavity with virtually flat surface, lacking platform; relatively high-arched M elements, other elements of a generalized polygnathid appearance.
Hindeodontoides, with the Viséan type species H. spiculus, is an alternative nomenclatorial option for species affiliated here in Pandorinellina. Dasbergina is rooted in the Pandorinellina lineage and the transition from P. vulgaris to D. stabilis seems to be continuous.
