type. That is in so far as metasternal and abdominal sclerites are not absent in 

 the Coccidae. 



The relationships with the basic margaroid male and the diaspidoid male, as 

 expressed by the characters shared with the lecanoid male, is shown in Table 5.

Showing Relationships of Lecanoid Male with the Margaroid 

 and Diaspidoid Types 



Margaroid Lecanoid I >iaspidoid 



A. Primitive characters: 



1. Head well sclerotized. X X 



2. Tentorium present. X- 



3. Distinct propleural apophyses present. X 



B. Specialized characters: 



1 . Compound eyes absent. X 



2. Lateral branches of midcranial ridge 

 present. 



3. Cranial apophysis long. 



4. Pronotal ridges present. 



5. Post-tergites small. 



6. Prescutal ridges shifted medially. 



7. 1'realare differentiated into a 



triangular sclerite. X X 



8. Subepisternal ridge detached from 



marginal ridge. X X 



9. Abdominal spiracles absent. X X 



From Table 5 it can be seen that the lecanoids and diaspidoids have a large 

 number (9) of specialized characters in common, whereas 3 primitive ones are 

 shared by the lecanoids and margaroids. It can therefore be stated that the 

 lecanoids are more closely related to the diaspidoids than to the margaroids and 

 also that they are more specialized than the margaroids but less than the diaspidoids 

 This conclusion confirms the views of Theron (1958) and Ghauri (1962).
