Cyclominae
Cyclominae is a subfamily 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 genera showing closer affinities to South American lineages than to geographically proximate relatives.
Gesneria
Gesneria is a genus of approximately 50–62 species of flowering plants in the family Gesneriaceae, native primarily to Caribbean islands with rare South American exceptions. The genus is distinguished by woody shrub or subshrub habit and alternate leaf arrangement—unusual in the family where decussate leaves are typical. Gesneria is classified in tribe Gesnerieae alongside Bellonia, Pheidonocarpa, and Rhytidophyllum. The genus exhibits high endemism in Caribbean biodiversity hotspots, with many species restricted to single mountain ranges or islands.
Kessleria
Kessleria is a genus of small moths in the family Yponomeutidae, first described by Nowicki in 1864. The genus contains approximately 35 recognized species distributed primarily across the Palearctic region, with additional species found in Madagascar, New Guinea, and Japan. Many species exhibit narrow geographic ranges and are associated with high-elevation or insular habitats. The genus has been subject to significant taxonomic revision, particularly by Huemer and colleagues, who used DNA barcoding to clarify species boundaries.
