Aphanommata
Aphanommata is a genus of weevils (Coleoptera: Curculionidae: Cossoninae) endemic to the Cape Verde archipelago in the Old World. The genus was erected by Wollaston in 1873 and currently includes three species from Cape Verde: A. euphorbiarum (Santo Antão), A. kuscheli (São Nicolau), and A. strakai (Fogo). A fourth species, A. filum, occurs elsewhere in the Old World. The genus has been subject to recent taxonomic revision including descriptions of larval morphology and analysis of vertical and inter-insular distribution patterns.
Cossonini
Cossonini is a tribe of weevils within the subfamily Cossoninae, family Curculionidae. The tribe contains approximately 60 described genera distributed across multiple continents. Members of this tribe are generally small to medium-sized weevils associated with wood-boring or bark-inhabiting habits. The group was established by Schönherr in 1825 and remains taxonomically active with ongoing revisions of constituent genera.
Dryotribini
Dryotribini is a tribe of weevils within the subfamily Cossoninae of the family Curculionidae. The tribe contains approximately 60 described genera distributed across multiple continents. Members of this tribe are generally small, cryptic weevils associated with dead or decaying plant material. The group has been documented in both temperate and tropical regions, with notable diversity in the Pacific islands and New Zealand.
Lechriops griseus
Lechriops griseus is a species of weevil in the family Curculionidae, subfamily Cossoninae. Members of the genus Lechriops are small weevils associated with coniferous trees, where larvae bore under bark on trunks and larger branches. The species epithet "griseus" (Latin for "gray") likely refers to the coloration of the adult beetle. This species is part of a genus containing multiple species with similar bark-boring habits in pine and related conifers.
Onycholipini
Onycholipini is a tribe of weevils in the subfamily Cossoninae, established by Alonso-Zarazaga and Lyal in 1999. The tribe includes at least four genera—Dipnotyphlus, Hauseriola, Leipommata, and Onycholips—plus Halorhynchus, which was transferred from Pentarthrini. Members are specialized for fossorial and psammophilous (sand-dwelling) lifestyles, with adaptations including reduced or absent eyes, compact body form, and modified legs for burrowing. The tribe has a disjunct distribution across coastal regions of the Mediterranean, Macaronesia, Arabia, and Australasia, with some species exhibiting transoceanic dispersal capabilities.
Pselactus spadix
Pselactus spadix is a wood-boring weevil in the subfamily Cossoninae, native to Europe but also recorded in North America and the Azores. It develops within timber, particularly in marine and coastal environments, and can complete its entire life cycle without emerging from wood. The species is known for distinctive circular emergence holes and tunneling patterns in timber.
Rhyncolini
Rhyncolini is a tribe of weevils within the subfamily Cossoninae (family Curculionidae). The tribe comprises approximately 50 described genera distributed across multiple continents. Members of this tribe are characterized by their association with dead or decaying wood, where they develop as larvae. The genus Rhyncolus serves as the type genus for the tribe.
Rhyncolus minor
Rhyncolus minor is a species of weevil in the family Curculionidae, subfamily Cossoninae. Members of the genus Rhyncolus are typically associated with dead wood and are considered secondary colonizers of decaying timber. This species is part of a group of small, cylindrical weevils characterized by elongated rostra and fossorial (burrowing) habits.
