Type-species: Copidosonia koehleri Blanchard. Orig. desig. 



This is a large, cosmopolitan genus whose members are polyembryonic parasites of Lepidop- 

 tera. Polyembryony in this instance seems to be an evolutionary strategy whereby a parasite of 

 comparatively low reproductive potential has succeeded in maximizing its efficiency by 

 completely consuming a host sometimes thousands of times larger than its own body size.
