Summary 
Three new megalyrid genera and species from the Neotropical 
region are described and illustrated: Rigel chiliensis Shaw, 
Cryptalyra plaumanni Shaw, and Neodinapsis peckorum Shaw. 
These are the first Megalyridae described from South America. A 
diagnosis for the family and a key to neotropical species are given. 
Preliminary ideas on phylogenetic relationships are discussed.
