Other common names:
guentheri: Brothers Island Tuatara, North Brother Island Tuatara, (Günther's Tuatara)
punctatus: Cook Strait Tuatara
Remarks:
Daugherty, Cree, Hay & Thompson (1990) revalidated guentheri as a separate species, but Hay, Sarre, Lambert, Allendorf & Daugherty (2010) synonymized it
again with punctatus.
See also Thompson, Daugherty, Cree, French, Gillingham & Barwick (1992).
Individuals from the islands in the Cook Strait may prove to be a distinct subspecies.
The subspecies reischeki (known only from Little Barrier Island in the Hauraki Gulf) may be extinct.
It has not been seen since the late 1970s.
Previously, guentheri was restricted to North Brother Island, but it has now been introduced to several other islands in the Cook Strait.
Distribution:
New Zealand
(Cook Strait Islands,
North Island: outlying islands).
