This key and its associated factsheets are the result of a large amount of work by Stephen Pawson and Ian McLellan (FNZES) it was made possible by the assistance of many people. We would like to acknowledge the assistance of those that allowed us access to collections in their care, including; John Early and Rosemary Gilbert (Auckland War Memorial Museum), Grace Hall (NZ Arthopod Collection), Dr Ian Henderson (Private Collection, including copies of his specimen database), Phil Sirvid and Ricardo Palma (Te Papa), Simon Pollard (Canterbury Museum), Cody Fraser (Otago Museum) and Brian Patrick (Central Stories). Peter Zwick kindly translated original material from German to English, Jon Sullivan assisted with developing some R-code to sort database records and John Thyne helped to modify GIS scripts to allow mapping of species distributions.

A special mention is required of Brian Patrick who has allowed us to include photographs he collected over many years, without which the key would not be so lavishly illustrated. Furthermore Brian has been the most prolific collector of New Zealand stoneflies and his records form a significant portion of the specimen database.

We gratefully acknowledge the financial assistance of the Terrestrial and Freshwater Biodiversity Information System (TFBIS) Programme towards the preparation of this database and identification key. The TFBIS Programme is funded by the Government to help to achieve the goals of the New Zealand Biodiversity Strategy, and is administered by the Department of Conservation.
