Type species: Glaphyrites (Neoglaphyrites) bashkiricus Ruzhentsev, 1938, p.272 [OD].

A:   Conch moderately involute, with narrow or closed umbilicus. Umbilical wall steep.
G:   Suture-line like Bisatoceras, but with V-shaped umbilical lobe.

[Nassichuk, 1975, p.105: The conch of Neoglaphyrites is ellipsoidal and moderately involute;
the umbilicus is deep and is typically less than 15 per cent of the conch diameter but in
some species the ratio is closer to 20 per cent. The umbilical shoulder is sharply rounded
and the umbilical wall steep. Shell ornament is not preserved on the type species. On
Canadian Arctic materials, delicate growth lines form ventral and lateral sinuses and
ventrolateral and dorsolateral salients. The suture is characterized by broad prongs of
the ventral lobe that are separated by a high secondary ventral saddle; prongs closely
approximatel the width of the first lateral lobe. The first lateral saddle is evenly
rounded and is nearly symmetrical. The umbilical lobe is V-shaped and internal lobes are
deep and narrow].

[Andrianov 1985, p. 131: Bulunites, regarded as synonym of Neoglaphyrites:
Conch discoidal, with rapidly growing whorls in early growth stages. Umbilicus moderately tight.  Quite distinct radial ribs may be present on shell surface.  Sculpture thinly reticulated.  Constrictions form a very weak ventral sinus.  Ventral lobe wide, divided by a quite high saddle.  Prongs of ventral lobe indistinctly rounded or sharpened at base.  Lateral lobe quite wide, asymmetrical, with stronger rounded side facing umbilicus.  Umbilical lobe very wide but not deep.  Inner lateral lobe thin, asymmetrical.  Dorsal lobe also thin, wedge shaped.  Suture line formula (V1 V1) LU:ID.]
