Members of Rotoitidae are relatively rarely collected and their biology is unknown.


The family is characterised by having 14-segmented antennae in the female with a distinct 6-segmented clava, a basal vein in the fore wing, a transverse scutellum, extremely reduced (hidden) prepectus, and absence of notauli.


This unusual family of tiny wasps (1–  2 mm) was originally thought to be endemic to New Zealand but has now also been recorded from Chile, indicating an archaic Gondwanan distribution. In New Zealand it is known from a single genus Rotoita and two, possibly three species, only one of which is described.

Further information about the Rotoitidae can be found in Boucek & Noyes 1987, Gibson 1993, Gibson & Huber 2000, Noyes & Valentine 1989 & Noyes 2001.
