Ceutorhynchinae
Minute Seed Weevils
Ceutorhynchinae is a large subfamily of minute seed weevils within Curculionidae, comprising over 150 genera and more than 1,000 described species worldwide. The subfamily is predominantly phytophagous and exhibits strong associations with Brassicaceae, though host plant relationships vary across genera. The genus Ceutorhynchus is particularly diverse and includes significant agricultural pests such as the cabbage seedpod weevil (Ceutorhynchus obstrictus), as well as species with potential for biological control of weeds. The subfamily shows highest diversity in the Holarctic region, especially the Palaearctic.
Cnemogonus
minute seed weevils
Cnemogonus is a genus of small weevils in the family Curculionidae, established by LeConte in 1876. The genus comprises approximately five described species distributed primarily in North America and Europe. These beetles are commonly referred to as minute seed weevils, reflecting their small body size and likely association with seeds as a food source. The genus includes the notable species Cnemogonus epilobii, which has been associated with willowherb plants (Epilobium).
Nedyus
minute seed weevils
Nedyus is a genus of minute seed weevils in the family Curculionidae, established by Carl Johan Schoenherr in 1825. The genus contains more than 50 described species. These beetles are small and associated with seeds as their common name suggests. Records indicate presence in northern Europe including Denmark, Norway, and Sweden.
Neophytobius
minute seed weevils
Neophytobius is a genus of minute seed weevils in the beetle family Curculionidae, established by H. Wagner in 1936. The genus contains at least two described species: Neophytobius cavifrons and Neophytobius muricatus. These are small beetles associated with seed feeding habits, typical of many Curculionidae.
Perigaster
minute seed weevils
Perigaster is a genus of minute seed weevils in the beetle family Curculionidae, established by Dietz in 1896. The genus contains approximately seven described species distributed in North America. These small weevils are associated with seeds, though specific host relationships remain poorly documented for most species. The immature stages of at least one species, P. cretura, have been described.
Plocetes
leguminous seed weevils
Plocetes is a genus of weevils in the family Curculionidae comprising over 60 described species. The genus was established by J.L. LeConte in 1876. Members are commonly known as leguminous seed weevils, indicating an association with legume plants. The genus is taxonomically stable and accepted across major biodiversity databases.
