Benneydale Ironclad Beetle (Pycnomerus sp.)

This up to now undescribed species is known exclusively from subfossil remains that were recovered from deposits near Benneydale, a small town in the Waitomo District of western North Island, New Zealand. [1]

The species is now extinct, it is one of countless large insect species that were eaten into extinction by Polynesian Rats (Rattus exulans (Peale)) that had been introduced by the ancestors of the Maori when they first arrived in New Zealand.
