Rotoitidae

The Rotoitidae are a very small family of rare, relictual parasitic wasps in the superfamily Chalcidoidea, known primarily from fossils (14 extinct species in two genera, "Baeomorpha" and "Taimyromorpha"). Only two extant species are known, each in its own genus, one from New Zealand and one from Chile, and little is known about their biology. Females of the Chilean species, "Chiloe micropteron", have their wings reduced to tiny bristles. Most fossil species are known from the Taimyr amber of Russia and Canadian amber, but one species, "Baeomorpha liorum" is known from the Burmese amber.
Rotoitids are very close to the base of the chalcidoid family tree, presently considered to be the first "branch" taxon after the Mymaridae.
