Description

The Cryptorhynchinae is a large subfamily of weevils (Curculionidae), with some 6000 species. They are merged into the Baridinae, Curculioninae or Molytinae in some treatments.^[1]

They are distinguished by having their rostrum (snout) backwardly directed between their fore coxae in repose, and fitting within a protective channel that usually ends in a cup-like structure on the mesosternum (ventral mid thoracic segment).^[2] The ends of the tibiae also bear an uncus (small hook-like extensions).

Some species are considered agricultural pests, such as the mango seed weevil Sternochetus mangiferae, but the great majority of species live in primary forests, often on deadwood and are threatened by habitat loss.
