Cremnops
Pegasus wasps
Cremnops is a genus of braconid wasps in the subfamily Agathidinae, commonly called 'Pegasus wasps' due to their distinctive elongated, horse-like head shape. These relatively large braconids (6–10 mm) are known parasitoids of caterpillars in the families Pyralidae and Crambidae. The genus occurs in terrestrial habitats worldwide, with documented species in North America, Europe, Japan, and the Middle East. Thirty-three New World species have been revised, including five described in 2015.
Diapriinae
Diapriinae is a subfamily of minute parasitoid wasps within the family Diapriidae. Members are typically 1–8 mm in length, with most species averaging 2–4 mm. They are characterized by a distinctive ledge-like extension of the face above the clypeus (the "shelf face"), from which the antennae originate. The subfamily contains three tribes: Diapriini, Psilini, and Spilomicrini. Most species are parasitoids of Diptera larvae and pupae, particularly fungus gnats (Mycetophilidae and Sciaridae), though some lineages have evolved specialized associations with ants. Many species remain undescribed, with an estimated 4,500 species worldwide compared to approximately 2,300 currently described.
Psilochalcis
Psilochalcis is a genus of chalcidid wasps in the family Chalcididae, established by Kieffer in 1905. The genus contains at least 20 described species, with additional undescribed species known from North America. Two species, P. minuta and P. quadratis, have been studied in detail in the Eastern Great Basin of Utah, where they exhibit habitat-specific associations with pinyon/juniper and cheatgrass-dominated vegetation respectively. Members of this genus are parasitoid wasps, with at least one species documented to oviposit in the pupal stage of host insects.
