Cis boleti
Cis boleti is a minute ciid beetle (2.8–4 mm) with uniform brown coloration. It inhabits the fruiting bodies of polypore fungi, including Piptoporus betulinus, Trametes, and Coriolus versicolor. The species is difficult to distinguish from closely related Cis species without examination of male genitalia. Its feeding activity reduces the reproductive fitness of host fungi by damaging the spore-producing hymenium.
Downeshelea
Downeshelea is a genus of predaceous biting midges in the family Ceratopogonidae, tribe Ceratopogonini. The genus was established by Wirth and Grogan based on the Monohelea multilineata species group and currently comprises over 60 species worldwide, with approximately 46 species in the Neotropics. Adult females are predatory, feeding primarily on adult Chironomidae, and may contribute to biological control of pest populations in agricultural settings.
Eulasiona
Eulasiona is a genus of tachinid flies established by Townsend in 1892. The genus currently contains 12 described species distributed primarily in the Nearctic and Neotropical regions. As members of the family Tachinidae, these flies are parasitoids, though specific host associations for most Eulasiona species remain undocumented. The genus is classified in the subfamily Dexiinae and tribe Voriini.
Protogygia
Protogygia is a genus of noctuid moths described by McDunnough in 1929, comprising approximately 17 described species distributed primarily in western North America. The genus is characterized by medium-sized adults with distinctive wing patterning and is associated with arid and semi-arid habitats, particularly active sand dune systems. Species identification relies heavily on male genitalia morphology, with several species groups recognized based on structural features of the uncus and clasper. The genus includes recently described species, reflecting ongoing taxonomic refinement in this cryptic group.
