Genus MESIDIA Foerster 



Mesidia Foerster, 1856. Hym. Stud., v. 2, p. 30. No species included. 

 Type-species: Mesidia puviila Mayr. Subsequent monotypy. 



This small Holarctic genus is composed of primary internal aphid parasites. 



Foerster(1856) described Mesidia in a keybut did not include any species. Subsequently, Mayr 

 (1904) described M. punnla which was the first and only included species. Mercet (1928) in- 

 dicated and Nowicki (1929) suggested that puniila was a junior synonym of Myina annulipes 

 Walker. Graham (1961) was unable to find the type-specimen of annulipes, but on the basis of 

 three collections of specimens agreeing with Walker's original decription, Nowicki's examination 

 of the type of piimila, and Mercet's illustration of the male antenna of the specimen thought to 

 be annulipes, Graham concluded the two were synonymous.
