Family Mymarommatidae
6 spp. in 2 genera in our area.
Only 10 living species in 1 genus have been described, others are known as fossils.
0.4 to 0.7 mm.
See comment here: "The distinguishing characters of the family are a 2-segmented petiole (other chalcidoids have a 1-segmented petiole or are indistinctly petiolate), forewing with a reticulate surface (smooth in other chalcidoids) and a marginal fringe of long setae, face triangular in frontal view with mandibles not meeting (round to square in other chalcidoids, occasionally approaching an inverted triangle in a few species and with mandibles meeting except for a few eulophid species), and the metanotum and propodeum without a visible suture between the sections (chalcidoids with a suture). Palaeomymar is the only current genus."
They are thought to be parasitoids of insect's eggs.
