Brevicornu
Brevicornu is a genus of fungus gnats in the family Mycetophilidae, established by Marshall in 1896. The genus has a cosmopolitan distribution with confirmed records from Europe, including Denmark, Norway, and Sweden. As members of Mycetophilidae, adults are small, delicate flies associated with fungal habitats. The genus includes at least three described species: Brevicornu affinis, B. amplum, and B. foliatum.
Mycetophilinae
fungus gnats
Mycetophilinae is a subfamily of fungus gnats within the family Mycetophilidae. It contains more than 30 genera and approximately 2,000 described species, organized into two tribes: Exechiini and Mycetophilini. Members are classified in the suborder Nematocera, a group of 'primitive' flies characterized by aquatic or moisture-dependent larval stages. The subfamily is distinguished from related fungus gnat subfamilies by specific morphological and taxonomic criteria, though precise diagnostic features for the subfamily level are not detailed in available sources.
