Fungus-weevils
Guides
Allandrus
Allandrus is a genus of fungus weevils in the family Anthribidae, established by LeConte in 1876. The genus comprises nine described species distributed across North America, Europe, and the Comoros. Members are associated with fungal hosts, consistent with the ecological profile of Anthribidae.
Anthribidae
fungus weevils
Anthribidae is a family of beetles commonly known as fungus weevils, distinguished from true weevils (Curculionidae) by their straight, non-elbowed antennae. Members of this family typically possess thread-like antennae that may exceed body length, representing the longest antennae among all Curculionoidea. The labrum appears as a separate segment from the clypeus, and maxillary palps are notably long and projecting. Most species feed on fungi or decaying plant matter, with larvae developing within dead wood. Some members exhibit unusual feeding habits: Choraginae includes seed-feeding species, a few are stored product pests, and the genus Anthribus uniquely preys upon soft scale insects.
Anthribinae
fungus weevils
Anthribinae is a subfamily of fungus weevils within the family Anthribidae. The subfamily contains over 50 genera and more than 80 described species. Members are distributed across multiple biogeographic regions including the Neotropics, New Caledonia, Vanuatu, and North America. Taxonomic revisions have significantly expanded known diversity in some regions, with New Caledonian fauna increasing from 14 to 56 species.
Anthribus
fungus weevils
Anthribus is a genus of fungus weevils in the family Anthribidae. Species occur in forest habitats including coniferous, deciduous, and mixed forests. Adults of Anthribus nebulosus have been observed to overwinter in bark crevices of coniferous trees with thicker bark. Flight activity is seasonal and weather-sensitive, with observed activity from May to July in central European populations.
Choraginae
fungus weevils
Choraginae is a subfamily of fungus weevils within the beetle family Anthribidae. The subfamily comprises approximately 9 genera, with authoritative sources differing on species count—estimates range from at least 20 to more than 180 described species. The subfamily includes economically significant genera such as Araecerus, which contains stored product pests. Choraginae is distinguished from other anthribid subfamilies by morphological and biological characteristics associated with their fungal associations.
Goniocloeus
fungus weevils
Goniocloeus is a genus of fungus weevils in the beetle family Anthribidae, established by Karl Jordan in 1904. The genus contains at least 40 described species. Members of this genus are classified within the weevil superfamily Curculionoidea, though fungus weevils in Anthribidae are distinguished from true weevils (Curculionidae) by their less elongated rostrum. The genus has been documented in at least 107 iNaturalist observations.
Phoenicobiella
Phoenicobiella is a genus of fungus weevils in the family Anthribidae, established by T.D.A. Cockerell in 1906. Members of this genus are small beetles associated with fungal substrates. The genus contains relatively few described species and has been documented primarily from North America. As with other anthribids, adults and larvae are likely mycophagous.
Piesocorynini
fungus weevils
Piesocorynini is a tribe of fungus weevils (family Anthribidae) established by Valentine in 1960. The tribe contains at least two genera, Brachycorynus and Piesocorynus, with approximately eight described species. Members of this tribe are distributed in the Neotropical region, with records from Nicaragua, Brazil, and Ecuador. A key diagnostic feature used to distinguish genera within this tribe is mandible shape.
Platyrhinini
fungus weevils
Platyrhinini is a tribe of fungus weevils within the family Anthribidae, containing at least 3 genera and more than 40 described species. Members of this tribe are classified under the Coleoptera order and are part of the diverse weevil superfamily Curculionoidea. The tribe includes the genera Goniocloeus, Trachitropis, and Trachytropis. These beetles are associated with fungal habitats, consistent with the ecology of the family Anthribidae.
Platystomini
fungus weevils
Platystomini is a tribe of fungus weevils within the beetle family Anthribidae. The tribe contains at least 24 described genera, with over 100 species recorded in North America and additional species distributed globally. Members of this tribe are characterized by their association with fungal hosts and their morphological adaptations for this ecological niche. The genus Platystomos, established in 1791, serves as the type genus for the tribe.
Stenocerini
Stenocerini is a tribe of fungus weevils within the subfamily Anthribinae of the beetle family Anthribidae. The tribe comprises at least sixteen genera, including Stenocerus (the type genus), Allandrus, and Helmoreus. Members are classified as fungus weevils, indicating an association with fungal resources. The tribe has a documented presence across multiple continents based on observation records.
Trigonorhinus
fungus weevils
Trigonorhinus is a genus of fungus weevils in the beetle family Anthribidae, comprising approximately 15-16 described species. The genus includes wood-boring species that develop in plant tissues, with at least one species documented as a pest of Caragana liouana in arid regions of China. A notable species, Trigonorhinus sp., has been demonstrated to rely on gut bacterial symbionts for production of male aggregation pheromones essential for mate attraction.
Zygaenodini
fungus weevils
Zygaenodini is a tribe of fungus weevils within the family Anthribidae, characterized by their association with fungal hosts. The tribe comprises at least three genera—Araeoderes, Eusphyrus, and Ormiscus—and approximately 20 described species. Members of this tribe are part of the broader fungus weevil group, which derives its common name from larval and adult feeding habits tied to fungi.
