Introduction

This species was originally described from Auckland, New Zealand, and is almost certainly an introduction to that country from Australia where it has been recorded at Dubbo in the southern part of the South Brigalow Belt of New South Wales and at Unley Park, a suburb of Adelaide, South Australia. Both Australian records were from Geranium sp (Geraniaceae).
