Klug, 2001, p.502: Shell of small to moderately large size, advolute to evolute, rarely gyroconical, thinly discoidal to discoidal; without or with a small imprint zone. Whorl cross section initially circular, later oval, subcircular or subtrapezoidal and sometimes with laterally flattened, converging flanks. Moderately wide to wide umbilicus, moderately large umbilical window (ca. 2 mm). Protoconch ovoid or subsphaerical, small (0.8 to 1.0 mm) and unsculptured. Moderately high to very high whorl expansion rates (2.3 to 3.5). Sculpture rursiradiate or rectiradiate, growth lines sometimes with a shallow lateral sinus, sometimes with a ventrolateral projection, and with a deep ventral sinus. On the venter, the growth lines are coarser. Suture line without or with a small internal lobe, with a broad lateral lobe and a small and narrow external lobe; septa without lateral inflexions.

Comparisons: The Teicherticeratidae BOGOSLOVSKY 1969 differ from the Mimosphinctidae ERBEN 1953 in the following characters: In the Teicherticeratidae, the whorl expansion rate is higher (2.3 to 3.5, Fig. 17) and the ribs are finer than in the Mimosphinctidae. Rarely, the terminal whorl is loosely coiled. Angular ventrolateral edges in combination with a tabular venter separate the Mimoceratidae STEINMANN 1890 from the Teicherticeratidae. Gently biconvex growth lines in species of the Palaeogoniatitinae indicate the ancestral relation of the Teicherticeratidae to the Mimagoniatitidae MILLER 1938. High ventrolateral projections in the growth lines and V-shaped internal lobes separate the latter family from the Teicherticeratidae. More conspicuous differences occur between the Teicherticeratidae and the Auguritidae BOGOSLOVSKY 1961 which have an oxyconic conch shape and additional lobes in the ventrolateral portions of the suture lines.

A:   Conch advolute or evolute, rarely gyrocone.
C:   Ribs rursiradiate or rectilinear, convex to biconvex.
