Apioninae
Guides
Apion
Apion is a genus of small weevils in the family Brentidae, historically classified in Apionidae. The genus was established by Johann Friedrich Wilhelm Herbst in 1797. Species in this genus are associated with various host plants, with some exhibiting narrow host specificity. The genus has been involved in notable nomenclatural complications, particularly regarding the name Eurhinus which was originally applied to a different apionine genus by Kirby in 1819 before being transferred to the baridine genus Eurhin.
Apionion crassum
Apionion crassum is a species of weevil in the family Curculionidae, subfamily Apioninae. Members of this genus are associated with leguminous plants. The species is characterized by a relatively robust body form compared to congeners.
Coelocephalapion antennatum
Coelocephalapion antennatum is a species of straight-snouted weevil in the family Brentidae. Species in this genus are small to minute beetles associated with plant material. The specific epithet "antennatum" refers to notable antennae characteristics. Like other members of Apioninae, this species likely has a narrow, elongated rostrum. Detailed biological studies of this particular species appear limited in published literature.
Coelocephalapion eriogoni
Coelocephalapion eriogoni is a species of straight-snouted weevil in the family Brentidae, subfamily Apioninae. The genus Coelocephalapion comprises small weevils associated with specific host plants, and this species is known from associations with Eriogonum (wild buckwheat) species. Like other apionine weevils, it likely exhibits a narrow host range tied to its larval development within plant tissues.
Coelocephalapion persimile
Coelocephalapion persimile is a species of straight-snouted weevil in the family Brentidae, subfamily Apioninae. Members of this genus are characterized by their compact body form and elongated rostrum. The species epithet "persimile" suggests close resemblance to another taxon. Like other brentids, it likely develops in plant tissues, though specific host associations remain undocumented.
Coelocephalapion subornatum
Coelocephalapion subornatum is a species of straight-snouted weevil in the family Brentidae. It belongs to a genus characterized by elongated, slender body forms and notably elongated rostrums. The species is documented from a limited number of observations, suggesting it may be uncommon or underreported. As with other members of Brentidae, it likely exhibits the family-typical elongated snout used for feeding and oviposition.
Cyladini
Cyladini is a tribe of weevils in the family Brentidae, subfamily Apioninae. The tribe includes economically significant pests of sweet potato, particularly the sweetpotato weevil (Cylas formicarius), which causes substantial damage to storage roots in tropical and subtropical production regions. Members of this tribe are characterized by their association with Convolvulaceae host plants and their status as specialized root-feeding pests.

Eutrichapion is a genus of small weevils in the family Brentidae, containing approximately eight described species. Members are characterized by a pear-shaped body form typical of the subfamily Apioninae. The genus was established by Reitter in 1916 and is distributed across parts of Europe and North America.
Fallapion
Fallapion is a genus of minute seed weevils in the family Brentidae (subfamily Apioninae), established by Kissinger in 1968. Members of this genus are small beetles characterized by their elongated rostrum and compact body form typical of apionine weevils. The genus is taxonomically distinct from the broader Apion genus complex, with species-level taxonomy requiring detailed morphological examination. Observations of this genus are relatively sparse, with limited documented occurrences in natural history databases.
Fallapion bischoffi
Fallapion bischoffi is a species of straight-snouted weevil in the family Brentidae. The genus Fallapion belongs to the subfamily Apioninae, a group of small weevils commonly known as seed weevils or apionids. As a member of the Brentidae, this species possesses the characteristic elongated snout (rostrum) typical of the family. Information regarding the specific biology and distribution of this species is limited in available sources.
Ischnopterapion virens
White Clover Weevil
Ischnopterapion virens is a small weevil species in the family Brentidae (subfamily Apioninae), commonly known as the White Clover Weevil. The species name 'virens' derives from Latin, meaning 'green,' likely referring to a greenish coloration characteristic of this beetle. The genus Ischnopterapion belongs to a group of weevils historically classified in the family Apionidae, now treated as a subfamily within Brentidae. This species has been documented across multiple island localities in the Azores archipelago (Faial, Pico, São Jorge, Santa Maria) as well as in New Brunswick, Canada, suggesting a broad but potentially disjunct distribution pattern.
Stenopterapion
Stenopterapion is a genus of weevils in the family Brentidae, established by Bokor in 1923. It contains approximately six described species distributed primarily in Europe. The genus is characterized by a pear-shaped body form typical of many brentid weevils. Species within this genus are relatively small and associated with herbaceous vegetation.
Trichapion
Trichapion is a genus of weevils in the family Brentidae (formerly placed in Apionidae). The genus was established by Wagner in 1912. Several species have been studied as biological control agents, particularly for invasive Sesbania weeds. Species were transferred from the genus Apion during taxonomic revisions.
Trichapion disparatum
Trichapion disparatum is a species of straight-snouted weevil in the family Brentidae, subfamily Apioninae. Members of this genus are small, slender weevils characterized by elongated rostrums and are commonly associated with leguminous host plants. The species is part of a taxonomically complex group of apionine weevils that have undergone significant revision in recent decades.
Trichapion leporinum
Trichapion leporinum is a species of straight-snouted weevil in the family Brentidae, described by Salsbury in 1987. The species epithet "leporinum" (hare-like) may reference a morphological trait or host association. Distribution records indicate presence in Manitoba, Canada. As a member of the Apioninae subfamily, it likely exhibits the slender body form and elongated rostrum characteristic of this group.
Trichapion modicum
Trichapion modicum is a species of straight-snouted weevil in the family Brentidae. The genus Trichapion was established to accommodate species previously placed in Apion, distinguished by morphological features of the rostrum and antennae. This species has been documented in Manitoba, Canada. Like other brentid weevils, it possesses an elongated rostrum and elbowed antennae. Specific ecological details for this species remain poorly documented.
Trichapion nigrum
Trichapion nigrum is a species of straight-snouted weevil in the family Brentidae, first described by Herbst in 1797. It belongs to a genus of small weevils characterized by elongated rostrums. The species has been documented in eastern Canada, with records from New Brunswick, Ontario, and Quebec. Like other members of Brentidae, it is likely associated with plant material, though specific ecological details remain poorly documented.
Trichapion roseae
Trichapion roseae is a small weevil in the family Brentidae, formerly placed in the family Apionidae. It is associated with plants in the genus Rosa (roses), with adults and larvae feeding on various parts of the host. The species is native to the Palearctic region and has been introduced to North America. It is recognized by its elongated rostrum and association with rose hosts.
Trichapion sp-nr-albidulum
Trichapion sp-nr-albidulum is an undescribed or near-identified species within the genus Trichapion, a group of small weevils in the family Brentidae. Members of this genus are characterized by their elongated, cylindrical bodies and distinctive rostrums. The 'sp-nr-albidulum' designation indicates a specimen that closely resembles T. albidulum but has not been formally confirmed to that species. These weevils are associated with leguminous host plants and are part of the diverse apionine fauna of North America.
