1957  Reticuloceratidae Librovich, p.252.

Superfam. Gastriocerataceae:

A:    Conch form variable, with broad whorl section and umbilicus. Early whorls commonly evolute.
B-D:  Shell smooth or sculptured. Transverse striae and constrictions, if present, with ventral sinus or salient.
G:   Prongs of ventral lobe relatively wide and pouched, its sides being curved or straight, but usually not divergent; median
      saddle half as high or higher than entire ventral lobe. First lateral saddle rounded or subacute. Sutural formulae:
      [Germ.] (E1EmE1)ALUI,    [Russ.] (V1V1)LU:ID.

Family Reticuloceratidae LIBROVICH, 1957:

A:   Conch form subdiscoidal, moderately to completely involute; umbilicus wide to narrow.
B:   Linear or biconvex growth lines, commonly crossed by longitudinal lirae thus forming reticulate ornamentation.
C:   Nodelike riblets and lateral plications in some forms.
E:   Ventrolateral furrows may be present.
G:   Suture-line relatively simple, in some forms with rounded elements. Prongs of ventral lobe usually well developed, but
      less pouched; median saddle usually about half as high as entire ventral lobe, or slightly higher. Advanced genera with
      wider lateral lobe and generally attenuate lobes.

Subfamily Reticuloceratinae LIBROVICH, 1957:

B-C: Ornamentation reticulate. Umbilical tubercles, nodelike riblets and lateral plications common.
A:   Conch form with tendency to develop oxycone ventral side.
G:   Suture-line variable, in some genera relatively simple, displaying rounded lobes. Ventral lobe relatively low.
