Family Mymarommatidae (False Fairy Wasps)
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."

A key to the families and genera can be found in Gibson 2007.
A key to the females of the genus Mymaromella from North America can be found in Huber et al. 2008.

May to September
They are thought to be parasitoids of insect's eggs.
These insects are very rarely collected, in part because of their small size.

"We suggest that the best chance of obtaining a definite rearing of any species of Mymarommatidae would be from Psocoptera eggs collected from bracket fungi, from litter and mosses collected in the subantarctic islands of New Zealand or from trunks of various ash species in north eastern North America." (Huber et al. 2008)
