Diadocidiidae
A small family of fungus gnats (Diptera) containing two genera: the extant Diadocidia with over 20 species and the extinct †Docidiadia from Burmese amber. Adults are minute woodland flies measuring 2.5–5.6 mm. The family was historically treated as a subfamily of Mycetophilidae but is now recognized as distinct and closely related to Keroplatidae, Bolitophilidae, and Ditomyiidae.
Lygistorrhinidae
Long-beaked Fungus Gnats
Lygistorrhinidae is a small family of flies in the order Diptera, commonly known as long-beaked fungus gnats. The family contains approximately 7 genera and at least 30 described species. These insects are distinguished by their elongated mouthparts and association with fungal habitats. They are relatively poorly studied compared to other fungus gnat families, with limited biological and ecological documentation.
