Nannochoristids are unusual mecopterans in that they
have an elateriform, aquatic larva. Adults are small creatures, with short
mouthparts uncharacteristic of the order. Their forewing venation is very
similar to that of dipterans, and they may be closely related. The geographical
distribution is clearly Gondwanian, with one genus found in New Zealand, and
the other genus found in southern Chile and southern Australia.
