This genus was originally created by Westwood in 
Philos. Magaz. (3) II 1833 p. 444 n. 21. Förster states 
(Hym. Stud. II p. 88) that he has three species of this 
genus, but his specimens are so dried and collapsed that 
he does not dare to enter upon a description of them. 
Westwood describes and figures the species evanescens 
and gives as generic character, that the subcosta is connec- 
ted to the edge of wing and the radius forms on exten- 
ding from the edge into the surface of the wing a smooth 
curve. This character being so typical it should be ima- 
gined that confusion was quite excluded, nevertheless 
as can be seen from the synonyms above, various genera 
have been made out of this easily recognisable genus. 
Even as late as 1897 Aurivillius creates the genus Oophthora, 
separating it as he does in his table of characters from 
Trichogramma (Westwood) as follows: »Trichogramma:
