Superfamily EVANIOIDEA 



By Robert W. Carlson 



This superfamily includes tiiree families, Evaniidae, Aulacidae, and Gasteruptiidae. There ap- 

 pears to be little evidence to indicate that the Aulacidae and Gasteruptiidae are actually related 

 to the Evaniidae. There does appear to be some evidence to indicate that the Aulacidae and 

 Gasteruptiidae are distantly related. Because there is no evidence to suggest that a common an- 

 cestor of Aulacidae and Gasteruptiidae would have been less closely related to ancestral 

 Evaniidae than to the ancestor of any other group, there is little reason for not maintaining 

 placement of the Aulacidae and Gasteruptiidae in the Evanioidea.

Family EVANIIDAE 



Members of this family are parasitic within the egg cases of cockroaches. Known hosts of the 

 evaniids found in North America are members of the cockroach families Blattidae and Blatel- 

 lidae. Species of Evaniidae are most numerous in the tropics.

 because appendigaater has been reared from P. amevicana in other parts of the world 

 there is no reason to doubt that it serves as a host in North America. I am not aware of
