see text Balvia is an ammonoid cephalopod genus from the Upper Devonian belonging to the goniatitid family Prionoceratidae.

Balvia has a small, lenticular to subglobular shell with a punctate umbilicus, that is completely involute.

Growth lines are fine, forward slanting, concavo-convex; indicate well developed ventrolateral salients and hyponomic sinus.

Flanks have several weak constrictions, which usually swing forward at venter to form grooves bounding a median keel.

Balvia was named by Dieter Korn in 1994 with the redescription of the type species, Gattendorfia globularis originally described by Schmidt in 1924.
