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.
Eubulus
hidden snout weevils
Eubulus is a genus of hidden snout weevils in the family Curculionidae, established by Kirsch in 1870. The genus contains at least 200 described species. These beetles are characterized by a concealed rostrum that is not visible from above, a trait that distinguishes them from many other weevil genera.
Gasterocercini
hidden snout weevils
Gasterocercini is a tribe of weevils within the family Curculionidae, commonly referred to as hidden snout weevils. The tribe contains at least four genera—Cophes, Episcirrus, Hohonus, and Rhynchus—with approximately eight described species. These weevils are part of the enormous radiation of snout beetles, though specific biological details for the tribe as a whole remain poorly documented.
Liometophilus
hidden snout weevils
Liometophilus is a genus of hidden snout weevils in the family Curculionidae, established by H.C. Fall in 1912. The genus contains at least two described species: L. manni and L. manui. As members of the "hidden snout weevils" group, species in this genus possess a distinctive rostrum that can be retracted into a ventral groove.
Phyrdenus
hidden snout weevils
Phyrdenus is a genus of weevils in the family Curculionidae, commonly known as hidden snout weevils. The genus was established by John Lawrence LeConte in 1876 and contains more than 20 described species. Members of this genus are part of the diverse Curculionidae family, the largest family of beetles. The common name "hidden snout weevils" refers to a morphological characteristic of the rostrum structure in these beetles.
Tyloderma
hidden snout weevils
Tyloderma is a genus of hidden snout weevils in the family Curculionidae. The genus contains at least 77 described species distributed across North, Central, and South America. One species, Tyloderma fragariae, is a documented agricultural pest of strawberry plants in North America. Members of this genus are characterized by their concealed rostrum, a trait that distinguishes them from many other weevil groups.
