In conjunction with our collaborative studies of Nearctic Encyrtidae we 
had the opportunity to study the type-species of Zaomma Ashmead. Ash- 
mead based this genus on Encyrtus cirgentipes Howard (type-locality St. 
Vincent, West Indies). Since the original description, the genus has re¬ 
mained monotypic and an enigma to many students of the Encyrtidae. Our 
study of Zaomma argentipes (Howard) has revealed the following new syn¬ 
onymy. 
Zaomma Ashmead 
Zaomma Ashmead, 1900. Proc. U.S. Natl. Mus. 22(1202): 340, 401. Type-

YMY. Type-species: Apterencyrtus pulchricornis Ashmead. Monotypic.
