C. turbotti, endemic to Manawatāwhi / Three Kings Islands northwest of New Zealand, was described as a species in 1950 by Thomas E.

[4] Woodward later revised this designation in 1952, describing it as a subspecies of Cermatulus nasalis,[5] however some authors such as Donald B. Thomas consider this to be a separate species.

[8] Cermatulus nasalis is predatory and feeds on a variety of insect species, plunging its beak into its prey and sucking out the body fluids.

[8] The female lays a batch of about thirty black eggs in three neat rows, on a leaf or patch of bark.

The newly hatched nymphs are red with black heads and feed at first on the bacteria that coat the eggs, and also on plant sap.
