Boletina
fungus gnats
Boletina is a species-rich genus of fungus gnats in the family Mycetophilidae, characterized by a mainly Holarctic distribution. The genus has historically been taxonomically challenging due to morphological similarities among species and paraphyletic relationships with related genera including Aglaomyia, Coelosia, and Gnoriste. Recent molecular phylogenetic studies and taxonomic revisions have clarified some relationships, though the genus remains under active investigation. Boletina species are particularly diverse in northern Europe, where ongoing research continues to reveal new species.
Brachyopini
Chrysogastrini
Brachyopini is a tribe of hoverflies (Diptera: Syrphidae) in the subfamily Eristalinae. The tribe contains approximately 20 genera divided into two subtribes: Brachyopina and Spheginina. Members are generally darker and less colorful than many other hoverflies, though some genera such as Chrysogaster exhibit metallic luster. The tribe has been recorded across Europe including the Iberian Peninsula and Ukraine, with new species continuing to be described.
