Cyclominae
Tribe Guides
1Cyclominae is a of weevils (Curculionidae) comprising seven tribes: Amycterini, Aterpini, Cyclomini, Dichotrachelini, Hipporhinini, Listroderini, Notiomimetini, and Rhythirrinini. The subfamily exhibits a disjunct global distribution, with significant radiations in southern South America, southern Africa, Australia, and the western Mediterranean region. Phylogenetic studies indicate complex evolutionary relationships among constituent tribes, with some Palaearctic showing closer affinities to South American lineages than to geographically proximate relatives.

Habitat
associations vary considerably among tribes and . Members of the genus Dichotrachelus are associated with saxicolous environments in alpine and subalpine zones of the European Alps and Apennines, where they occur on rocky slopes and scree fields. The South African genus Khoisan occurs in arid and semi-arid karroid vegetation of the Northern and Western Cape provinces. Australian Amycterini, including Amycterus and Xenommamycterus, inhabit tropical rock desert and Pilbara ironstone formations in Western Australia. The genus Macrostyphlus in South America is associated with mosses.
Distribution
Southern South America (Argentina, Chile); southern Africa (South Africa, Namibia); Australia (Western Australia, particularly Pilbara region); western Mediterranean region including Iberian Peninsula, northern Africa, southern France, Alps, and Apennines. The shows pronounced Gondwanan distribution patterns with relictual in temperate regions of the Southern Hemisphere and isolated Palaearctic representatives.
Host Associations
- Saxifraga caesia - of Dichotrachelus pesarinii in the central southern Alps
- Saxifraga oppositifolia - of Dichotrachelus sulcipennis group members
- mosses - association reported for Macrostyphlus and some related South American
Similar Taxa
- EntiminaeBoth are of Curculionidae with broad distributions; Cyclominae can be distinguished by tribal-level characters and phylogenetic placement, though external may appear convergent in some lineages
- HyperinaeOccasionally confused in agricultural contexts; Hypera postica (Hyperinae) co-occurs with Listroderes costirostris (Cyclominae) on celery crops, but Hyperinae possess distinct genitalic and larval characters
