The weevils (Curculionidae) are in fact the most species-rich family of the whole animal kingdom, the family is divided into several subfamilies of which the Cossininae is one.

***

The subfossil record of the island of Rimatara, Austral Islands has produced the remains of at least 18 (!) genera/species of cossinine weevils, this shows how species-rich the island faunas once, before the arrival of humans, were … and, how much has already been lost.

The remains are currently under review by Nick Porch, an Australian entomologist specialized in subfossil insect remains.
