Diagnosis.

See introduction.

Differential diagnosis.

Gudeodiscus differs from the keeled shell of Sicradiscus by the rounded body whorl. Sicradiscus species having rounded body whorl differ from Gudeodiscus by the combination of small shells with glossy base, a strong apertural fold connected to the callus, and short or divided palatal plicae. In contrast, Gudeodiscus species have usually large, mainly finely ribbed shells with weak apertural folds free from the callus (often absent) and long, depressed Z-shaped palatal plicae.
