Subfamily SIGNIPHORINAE 



The names Signiphoridae and Thysanidae have been used interchangeably. Thysanus Walker 

 is older (1840) and Thysanidae was used in the 1951 edition of the catalog. Signiphorinae is used 

 here because it is the commonly used name. Signiphora Ashmead and Thysanus have been 

 synonymized. However, Rozanov (1965) and others have shown that the genera are distinct. The 

 Signiphorinae were characterized by Howard (1894). 



De Santis (1968) divided the Signiphoridae into the Signiphorinae and Thysaninae. His sub- 

 famiUes have been retained as tribes.
