Bonamia exitiosa Hine et al., 2001 is proposed instead of B. exitiosus as the valid name of Bonamia sp. infecting flat oysters Ostrea chilensis in New Zealand

A parasite of the dredge oyster Ostrea chilensis Philippi, previously known as Bonamia sp., was recently described and named Bonamia exitiosus, based on ultrastruc- tural and molecular evidence. The rules governing the names of organisms require correspondence of gender, and the name must be changed from B. exitiosus to B. exitiosa.
