Cryptorhynchinae
hidden-snout weevils
Cryptorhynchinae is a large subfamily of weevils (Curculionidae) comprising approximately 6,000 species. The subfamily is distinguished by a rostrum that folds backward between the fore coxae in repose, fitting within a protective channel on the mesoventrite. Molecular evidence supports its monophyly as an independent subfamily rather than inclusion within Molytinae. The group is most diverse in the Neotropics, Australia, and Oceania, with an evolutionary origin in the Late Cretaceous of South America.
