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.
Eupitheciini
Pug Moths, Pugs
Eupitheciini is a tribe of geometer moths in the subfamily Larentiinae, commonly known as pugs. With approximately 1,900 described species distributed across 47 genera, it is the most species-rich tribe in the family Geometridae. The genus Eupithecia alone contains roughly 1,400 species and is one of the largest insect genera globally. Members are typically small moths with narrow wings and cryptic coloration. Identification relies heavily on genitalia dissection due to morphological homogeneity among species.
Hypomicrogaster
Hypomicrogaster is a genus of braconid wasps in the subfamily Microgastrinae, containing over 40 described species. The genus was taxonomically revised in 2015, with 40 new species described and four previously named species redescribed. Species in this genus are parasitoids of Lepidoptera, with documented associations to 11 lepidopteran families and 52 confirmed host species feeding on 34 plant families. The genus is distributed across North, Central, and South America.
Orchestina
goblin spiders
Orchestina is a species-rich genus of tiny goblin spiders (family Oonopidae) containing over 180 extant species. Members measure 1.0–3.0 mm in body length and possess an enlarged fourth femur enabling jumping. The genus exhibits a nearly global distribution in the Northern Hemisphere south of 45°N, with highest diversity in Central and South America, Africa, and Asia. First described by Eugène Simon in 1882.
