Type species: Eonomismoceras shevyrevi Kuzina, 1974, p.29 [OD].

A:   Conch small, discoidal, with wide umbilicus; venter rounded.
B:   Growth lines biconvex, with strong ventro-lateral salient.

[KUZINA 1980, p.84: Conch not large, dactylicone, very thin.  Whorls very evolute.  Umbilicus wide.  Sculpture of radial
growth lines, which form a ventral and a lateral sinus, with quite a high salient  in between.  Ventral lobe narrow,
comperatively deep, with sharpened elements, which are parted by a low median saddle.  First lateral saddle rounded,
equal to ventral lobe in width.  Lateral lobe thin and short.]
