MORPHOLOGY AND TAXONOMY OF ADULT MALES 



The characters distinctly separating the macropterous males of Pseudococcidae 

 from those of Eriococcidae are listed in the following table (A) :

Puparia 



Table A 



Pseudococcidae 



Fluffy, loosely felted, with no 

 definite posterior opening. 



Postoccipital ridge : Weak, slender, U- or V-shaped. 



Terminal antennal 

 segments : 



Proepisternum : 



Elongated ; more or less 

 cylindrical. 



With the dorsal margin (and 

 sometimes also the ventral 

 margin) heavily sclerotized and 

 ridge-like. 



(5) 



Scutellum, in dorsal 

 view : 



Pentagonal. 



(6) 



Scutellar ridge : 



Absent. 



(7) 



Anterior and 

 posterior postalar 

 ridges : 



Well separated. 



(8) 



Mesopleural ridge : 



Interrupted above the coxal 

 articulation. 



(9) 



Trochanter : 



With the basal part longer 

 than the distal one. 



(IO) 



Ungual digitules : 



With acute tip. 



(«) 



Penial sheath : 



Basal part short, not fused 



(12) Aedeagus 



with the 9th tergite + the 

 10th segment ; anterior 

 margin of the slit-like opening 

 close to the basal ridge. 



Arises ventrally just behind 

 the basal ridge of the penial 

 sheath. 



Eriococcidae 



Compact, closely felted, 

 flattened, permanently split 

 along the posterior edge. 



Strongly developed, laterally 

 forked. 



Barrel-shaped ; the apical 

 segment distinctly pear- 

 shaped. 



Without any ridge-like 

 sclerotization. 



Transverse, rectangular. 



Present. 

 Anteriorly joined. 



Continuous above the coxal 

 articulation. 



With the basal part shorter 

 than the distal one. 



Apically knobbed. 



Basal part long, fused with 

 the 9th tergite, the 10th 

 segment forming together 

 cylindrical basal genital 

 capsule ; anterior margin of 

 the slit-like opening removed 

 far posteriorly. 



Removed backwards and 

 arises at a comparatively 

 large distance from the basal 

 ring of the genital capsule. 



The two families can be also separated by a number of other less well defined 

 characters (listed in table B), the taxonomic significance of which may be confirmed 

 as more information becomes available :
