The use of the name Zaomma instead of Apterencyrtus may disturb some 
encyrtid taxonomists and biological control specialists. Apterencyrtus has 
been widely used in the literature and is well represented in the Palearctic 
Region. However, the name Zaomma has not gone unused. Timberlake 
(1924) discussed it in his description of Synaspidia and provided additional 
descriptive notes. The International Commission should be consulted if 
workers believe that the use of Zaomma would cause instability of nomen¬ 
clature. 
The morphological characters used to identify this genus are similar to 
those of Apterencyrtus and Metapterencyrtus. We regard Zaomma as a 
member of the Cheiloneurini Hoffer as that tribe was characterized by Trja- 
pitzin (1973). This tribe is composed of primary and secondary parasites of 
scale insects. 
Species Previously Assigned to Apterencyrtus 
1. Apterencyrtus adeli Traboulsi. Traboulsi (1968) provided a compre¬ 
hensive diagnosis of this species and compared it to Apterencyrtus microph- 
agus, Apterencyrtus thomsoniscae Alam, and A. zonatus Alam. Study of 
Traboulsi’s description and illustrations shows that this species is conspe- 
cific with Z. lambinus (Walker). 
Graham (1969) synonymized A. thomsoniscae and A. zonatus with En- 
cyrtus lambinus Walker. Encyrtus laminus is considered valid because 
lambinus was an unused name. In this paper, we are using the name 
lambinus. The matter should be brought to the attention of the Com¬ 
mission of Zoological Nomenclature. 
2. Apterencyrtus africanus Risbec. Annecke and Insley (1971) have cat¬ 
aloged the Ethiopian Encyrtidae and Aphelinidae. In that catalog they note 
that this species was misplaced in Apterencyrtus. Annecke and Mynhardt 
(1973) regard this species as a member of Exoristobia Ashmead and we 
agree. 
3. Apterencyrtus trichomasthoides Hoffer. We regard this species as a 
member of Metablastothrix Sugonyayev NEW COMBINATION. Through 
the courtesy of Dr. A. Hoffer of Prague, V. A. Trjapitzin has studied a 
paratype female of this species. It is probably a synonym of M. truncati- 
pennis (Ferriere). 
Zaomma argentipes (Howard) 
This species was originally described by Howard (1894a) on the basis of 
a single female specimen taken at St. Vincent, West Indies. Subsequently 
Girault removed a forewing and the head and mounted them in Canada 
balsam. The head was smashed and fragmented. Thus it is not possible to 
give a comprehensive description. We have reconstructed the antenna (Fig.
