Tanysphyrus ater
Tanysphyrus ater is a small weevil species described by Blatchley in 1928. It belongs to the family Erirhinidae (sometimes placed in Brachyceridae or Curculionidae in different classifications), a group of primitive weevils. The species epithet 'ater' refers to its black coloration. Very little published information exists on its biology or ecology, with only scattered collection records from North America.
