Neoglaphyrites is a goniatitid ammonite that lived during the latest Pennsylvanian and early Permian.

Delicate growth lines forming ventral and lateral sinuses and ventrolateral and dorsolateral salients have been found on Canadian Arctic specimens.

The suture is characterized by the ventral lobe split into two broad prongs that are separated by a high median ventral saddle; prongs closely approximate the width of the first lateral lobe.

General consensus is that Neoglaphyrites belongs in the Bisatoceratidae, although this has not always been the case.

Miller et al 1957, in the Treatise on Invertebrate Paleontology, placed Neoglaphyrites in the Neoicoceratidae as a synonym for Eoasianites.
