11003-99203 Tuatara (Sphenodon punctatus) once recognised as a separate species named Gunthers tuatara (Sphenodon guntheri) for a short period from 1989 onwards. This population of approximately 400 characteristically small, strongly marked individuals are confined to North Brother Island in the Marlborough Sounds. However a re-examination of the genetic bases used to distinguish this species of tuatara has concluded they only represent geographic variants, and so only one species should be recognized.
