From Wikipedia, the free encyclopedia
Eutrichosomatidae is a family of parasatoid chalcid wasps.[1] Their bodies are black or metallic, with some species being covered in white hairs.[2] The genera Eutrichosoma and Peckania are distributed across the New World while Collessina is only found in Australia.[1] The genera Peckanius and Collessina are named after Dr Oswald Peck and D.H Colless respectively.[2] Both genera contain one species each while Eutrichosoma contains 3.[1]

Biology
The first instar larvae are active planidia that parasitize developing seed-feeding weevils.[1] Eggs are laid adjacent or away from the weevil egg and the larva must move to attach itself to the weevil larva.[3][1] The larva remains capable of locomotion until the weevil pupates in order to reattach itself as their host molts.[3] Due to their larval characteristics they are placed in a clade alongside Perilampidae and Eucharitidae.[3]
Taxonomy
Eutrichosomatidae was originally published as its own family it 1951, later in 1974 it was demoted to subfamily and placed in Pteromalidae[3] before being elevated back to family status in 2022.[4] It currently contains 3 genera with the genus Manineura being included in some sources:[5][1]
