Graeffe’s Ground Beetle was described in 2017 based on a single male specimen that had been collected sometimes between 1862 and 1870 on the mountains near Apia, the capital of Samoa on the island of ‘Upolu. This specimen was housed in the Muséum national d’Histoire naturelle, Paris, France and was only recently rediscovered.

The species is about 1,6 cm long.

Graeffe’s Ground Beetle has never been recorded since the collection of the type and is almost certainly extinct. [1]
