MORPHOLOGY AND TAXONOMY OF ADULT MALES 



ERIOCOCCIDAE 



Key to Genera 



Fleshy setae present on the legs. Prosternal setae present. Hamulohaltera 

 subequal in length to its apically hooked seta. Trochanter without long, 

 differentiated apical setae ERIOCOCCUS (p. 167) 



Fleshy setae absent on the legs. Prosternal setae absent. Hamulohaltera, 

 if present, i-6 or more times as long as its apically hooked seta. Trochanter 

 with a long apical seta .......... 2 



(1) Lateral arms of the midcranial ridge short and weak. Ocelli vestigial. Genal 

 setae 3 or less. Unidentified disc-like structures absent on the head. With 

 a small mouth tubercle. The body not more than twice as long as the 

 antennae. Antespiracular ventral setae present. Scutellum slightly longer 

 than scutum. Hamulohalterae and suspensorial sclerites entirely absent. 

 The body less than twice as long as the hind leg. Pleural setae of abdominal 

 segment VIII include one seta slightly longer than the others. Style rather 



straight in lateral view OVATICOCCUS (p. 179) 



[Only one species, O. agavium.] 



Lateral arms of the midcranial ridge well developed. Ocelli large. Genal 

 setae 4 or more. One or more disc-like structures present dorsally on each 

 side of the midcranial ridge. Mouth tubercle absent. The body more than 

 twice as long as the antennae. Antespiracular ventral setae absent. 

 Scutellum shorter than scutum. Hamulohalterae and suspensorial sclerites 

 well developed. The body more than twice as long as the hind leg. Pleural 

 setae of abdominal segment VIII include one seta about twice as long as 

 others. Style sinuated in lateral view . . . GOSSYPARIA (p. 182) 



[Only one species, G. spuria.] 



ERIOCOCCUS 



Key to Species 



Ventral part of the preocular ridge reduced. Cranial apophysis truncate. With 

 12 or more dorsal head setae ; setae of the ocular sclerites and the setae 

 between the ventral eyes present. Genal setae more than 7. Antennae 9- 

 segmented ; 3rd segment 2-5 or more times as long as the terminal ; capitate 

 sensory setae only present on the terminal segment. Lateropleurite with a 

 distinct membranous area. Prescutal setae 6 or more ; mesopisternal, 

 postmesostigmatal and basisternal setae present. Metatergal setae 4 or 

 more ; metapleural and postmetastigmatal setae present. Tergite of 

 abdominal segment VIII anteriorly bounded by differentiated heavy 

 sclerotization. The body 7-7 or more times as long as the tail setae of the 

 glandular pouches ........ E. buxi (p. 175) 



Preocular ridge well developed. Cranial apophysis bifurcate. With less 

 than 12 dorsal head setae ; setae of the ocular sclerite and the setae between 

 the ventral eyes absent. Genal setae less than 7. Antennae 10-segmented ; 

 3rd segment less than i-8 times as long as the terminal ; capitate sensory 

 setae present at least on the three terminal segments. Lateropleurite 

 without membranous areas. Prescutal setae 2 or less ; mesepisternal, 

 postmesostigmatal and basisternal setae absent. Metatergal setae 3 or less ; 

 metapleural and postmetastigmatal setae absent. Tergite of abdominal 

 segment VIII without anterior heavy sclerotization. The body usually 

 less than 7-7 times as long as the tail setae of the glandular pouches . . 2
