Genus Anomalacantha Loeblich and Tappan Richard N. Benson (29/10/2003)
After Benson, 1966, p. 169:
The genus Heterocantha was renamed Anomalacantha by Loeblich and Tappan (1961, Proc. Biol. Soc. Washington, 74, p. 223) because it is an invalid homonym. Diagnosis: main spines and secondary spines present with lateral branches.
