Overview
The biology of very few species is known, but most appear to be
parasitoids
of leaf-mining larvae or insect eggs. Keys to Australasian genera are included in Boucek (1988).
Description
Tetracampids are characterised by females having five tarsal segments, males four; the fore tibial spur small and straight; antenna with six (rarely five) funicular segments; pronotum long (greater than half the length of the mesoscutum) and rounded without prominent anterior corners; and the basal cell of the fore wing usually densely setose (hairy).
Distribution
The Tetracampidae are a small family, rarely collected. Only seven described species occur in Australia and the family is absent from New Zealand.
Further information about the Tetracampidae can be found in Boucek 1988, Gibson 1993 and Noyes 2001.
