Cryptorhynchinae
hidden-snout weevils
Cryptorhynchinae is a large subfamily of weevils (Curculionidae) comprising approximately 6,000 species. The subfamily is distinguished by a rostrum that folds backward between the fore coxae in repose, fitting within a protective channel on the mesoventrite. Molecular evidence supports its monophyly as an independent subfamily rather than inclusion within Molytinae. The group is most diverse in the Neotropics, Australia, and Oceania, with an evolutionary origin in the Late Cretaceous of South America.
Medeterinae
Medeterinae is a subfamily of long-legged flies (Dolichopodidae) comprising approximately 40 genera arranged in four tribes: Medeterini, Systenini, Thrypticini, and Udzungwomyiini. The group includes both extant and fossil genera, with several described from amber deposits. The subfamily is most diverse in tropical and subtropical regions, with particular richness in the Afrotropical and Oriental realms.
Micromyinae
Micromyine Wood Midges
Micromyinae is a subfamily of wood midges in the family Cecidomyiidae, comprising at least 55 genera and more than 650 described species. Members were formerly classified within subfamily Lestremiinae. All species in this subfamily are mycophagous, feeding on fungi. The subfamily includes numerous fossil genera preserved in amber deposits dating from the Albian to Eocene.
