Family ENCYRTIDAE 



By Gordon Gordh 



The higher classification of the Encyrtidae used in this catalog differs drastically from that 

 proposed in the 1951 edition. Some explanation is necessary. Burks has considered the Sig- 

 niphoridae and Aphelinidae as subfamilies of the Encyrtidae. In the 1951 catalog the aphelinids 

 were considered a subfamily of the Eulophidae and the signiphorids were treated as a distinct 

 family (Thysanidae). The aphelinids and signiphorids appear more nearly related to the Encyr- 

 tidae than to other families of chalcidoids. In placing the aphelinids under the Encyrtidae, the 

 subfamilies of apheUnids (.sex.sH Ferriere, 1965, Faune de I'Europe Bassin Medit, 1: 1-206) have 

 been relegated to tribal status. 



Recently Trjapitzin (1973, Ent. Rev. 52 (1): 118-125; Ent. Rev. 52 (2): 287-295) has treated the 

 higher classification of the Encyrtidae {sensu stricto) and provided a radical reorganization at 

 the tribal and subfamilial levels. His classification has been adopted in the present treatment of 

 the Encyrtidae. In so doing, however, the placement of several genera remains undecided. These 

 will be treated in a separate publication. 



In this section the term "cosmopolitan" means the species is found throughout North America. 



I thank D. Miller and M. Stoetzel (Systematic Entomology Laboratory, IIBIII, U. S. Dept. 

 Agr., Beltsville, Maryland) for providing correct names for homopterous hosts. D. P. Annecke 

 (Plant Protect. Res. Inst., Pretoria, South Africa) gave his advice on the placement of several 

 species earlier referred to Aphycun. 



The hosts cited in this section are only those reported for North America.

This genus is cosmopolitan and consists of approximately 45 described species which are pri- 

 mary internal parasites of aphids. Some species are useful in biological control of aphid pests.
