minute seed weevil
Neophytobius cavifrons is a of minute seed weevil in the Curculionidae, first described by Colonnelli in 1980. It is found in North America, with records from Alberta and British Columbia in Canada. As a member of the Neophytobius, it belongs to a group of small weevils associated with seeds. The species is known from only a handful of observations, indicating it is rarely encountered or poorly sampled.
