A new host and additional localities for the rare psyllid
Acizzia keithi was described as a monophagous species from the threatened plant Pultenaea glabra at a single, localised site and was therefore believed to be at risk of coextinction. However, following more sampling at sites outside of the known localities of P. glabra, the distribution and host range of A. keithi are expanded to include a congeneric common plant, Pultenaea flexilis. Pultenaea flexilis is broadly distributed throughout the coast and Great Dividing Range of New South Wales and into Queensland. Hence, even though A. keithi was rarely collected in this study, and remains at risk of local extinction on P. glabra at Cataract Falls, it is no longer considered to be a species at risk of coextinction.
