Of 18 sites surveyed in the Horowhenua District, seven sites provide habitat for P. traversi and do not contain Tradescantia. Five colonies of P. traversi are affected by Tradescantia, these are: Waiopehu Scenic Reserve, Prouse’s Bush, Kimberley Scenic Reserve, Ohau River Bush, and Hillas Covenant. Tradescantia infestation at these sites varies from heavy (Prouse’s Bush) to forest edge only (Hillas Covenant). Overall, Tradescantia affects a small proportion of snail habitat in the Horowhenua District. Our study of P. traversi at Prouse’s Bush, using harmonic radar to follow long-term movements and cotton tracks for short-term movements, indicates that this snail commonly occurs under Tradescantia, sometimes exclusively, and that many of the snails move regularly between leaf litter and this...

There is an urgent need for rapid and accurate diagnostic tools on this species. In order to meet this demand, we developed methods for identification of T. evansi in the field and laboratory based on damage symptoms, morphological characters and DNA sequences. To distinguish T. evansi from the previously recorded species a key to all species of Tetranychus in New Zealand is provided. DNA barcoding employing the mitochondrial COI gene enabled us to differentiate T. evansi from closely related species.
