A type specimen is held at the Natural History Museum, London.
The last known collection of this beetle, prior to its rediscovery, was by Thomas Hall who extensively sampled Pitt Island for beetles between 1906 and 1908.
He collected three specimens which are now held in the New Zealand Arthropod Collection.
