Tychanopais sp. ‘Fred Cave’

Fred Cave Weevil (Tychanopais sp.)

The Fred Cave Weevil is an up to now undescribed species that is known from a subfossil abdomen that was recovered from the deposits of a 14 m deep vertical limestone shaft on a farm in the Fred Cave Catchment in the Waitomo District in western North Island, New Zealand. [1]

The species is thought to be extinct; however, some few congeneric species still survive at rat-free offshore islets.
