Belidae
Primitive Weevils, Belids, Cycad Weevils (restricted usage)
Belidae is an ancient family of weevils distinguished from true weevils (Curculionidae) by straight rather than elbowed antennae. The family exhibits a relictual Gondwanan distribution, with extant species found primarily in the Australia–New Guinea–New Zealand region, South and Central America, Southeast Asia, Pacific islands, and scattered African localities. Belidae comprises two living subfamilies: Belinae and Oxycoryninae. The family has undergone significant host-plant shifts from ancestral conifer associations to diverse angiosperm lineages, including cycads, palms, and parasitic flowering plants.
Bolbomyia
Bolbomyia is a small genus of snipe flies comprising four species, including one fossil species from Baltic amber. It represents the sole genus in the family Bolbomyiidae, having been reclassified from Rhagionidae in 2010 based on morphological and phylogenetic evidence. The genus is characterized by diminutive size and distinctive wing pigmentation.
