Reported on the Cook Islands by P.J. Dale (McCormack 2007). Known only from Rarotonga.

Host plant.

Metrosideroscollina (J.R. Forst. & G. Forst.) A. Gray (Myrtaceae).

Remarks.

no specimens of this psyllid were collected by the authors. Photographs provided by G McCormack were consistent with the morphology of T.zimmermani, with the greatest difference shown in the wings (Figures 24, 27), with the Rarotongan specimens being shorter and with a less acute apex (Figure 24), than those from Raivaevae drawn by Tuthill (1942, Figure 27). However, since no specimens could be examined in person, this taxon is reported here based on the identification made by Dale. The distribution of T.zimmermani includes French Polynesia (Australs) (Tuthill 1942, Percy 2017).
