Differential diagnosis

Dicharax dohertyi (of which no specimens were available, see under D. dohertyi) and D. rugosus are similar in sculpture and aperture formation, but they have a higher spire. Dicharax trashidentatus is very similar to D. muspratti in shell and aperture shape and shell sculpture, but it also has a higher spire and denser R1 ribs. Dicharax rugosus is also similar due to the strong R1 ribs, the large distance between the inner and outer peristomes and the fringed aperture, but it has a higher spire.
