Category:-ii suffix

• ICZN 1999 Art. 33.4. Use of -i for -ii and vice versa, and other alternative spellings, in subsequent spellings of species-group names. The use of the genitive ending -i in a subsequent spelling of a species-group name that is a genitive based upon a personal name in which the correct original spelling ends with -ii, or vice versa, is deemed to be an incorrect subsequent spelling, even if the change in spelling is deliberate; the same rule applies to the endings -ae and -iae, -orum and -iorum, and -arum and -iarum.
  • Example. The subsequent use by Waterhouse of the spelling bennettii for the name established as Macropus bennetti Waterhouse, 1837 does not make the subsequent spelling an available name even if the act was intentional.
