OF PSEUDOCOCCIDAE & ERIOCOCCIDAE 179 



OVATICOCCUS Kloet, 1944 



Ovaticoccus agavium Douglas 



(Text-figs. 45, 46) 



Winged forms only known ; these dark reddish brown, with the thorax slightly lighter. 

 The males moderately robust, comparatively small, with moderately short antennae and 

 moderately long legs. Mounted specimens 1050-1204 (ii2o)u. long, 308-350 (336) u. wide at 

 mesothorax and 2128-2422 (2296) jo. wing expanse. 



Body setae : Antennae with about i2u. long fleshy setae and about twice as long hair-like 

 ones ; body and legs with hair-like setae only, much smaller than those of the antennae. 



Head : Subtetrahedron ; subtriangular in dorsal view and more or less rounded in front 

 view ; ventral preocular depression hardly indicated in lateral view. Length from apex to 

 postoccipital ridge 107-125 (n6)u. ; from apex to neck 159-177 {i6j)[l ; width across the 

 genae 198-207 (201) \x. Dorsal arm of midcranial ridge anteriorly continuous with the ventral 

 arm and posteriorly fading out before reaching the postoccipital ridge ; lateral arms indicated 

 by short, weak sclerotizations. Postoccipital ridge laterally giving off two small branches, 

 one anteriorly and the other slightly bent posteriorly. Preocular and postocular ridges well 

 separated ; preoral ridge slender. Eyes : Dorsal simple eyes not projecting beyond the outer 

 margins of the head in dorsal view ; their corneae 15-18 (17)10. in diameter and both separated 

 by 98-113 (107)0., i.e. 5-3-7-4 (60) times their diameter apart. Ventral simple eyes 15-21 

 (i8)|x in diameter and 43-55 (49) [x apart. Lateral ocellus vestigial and only represented by a 

 small sclerotized spot on the ocular sclerite, attached to the postocular ridge by means of a short 

 sclerotized arm. Cranial apophysis apically bifurcate. Tentorial bridge stout. Mouth 

 opening posteriorly situated on a small mouth tubercle. Dorsal head setae 6-9 (7-1) on each 

 side ; each gena with 2-3 (2-1) genal setae. Ventral head setae on each side : Setae between 

 the ventral eyes absent ; 2-4 (3-1) in the area of the ventral preocular depression, forming 

 on both sides transverse single or double rows ; anteriorly 1-2 (i-8) on each side of the ventral 

 arm of the midcranial ridge. 



Antennae : Rather filiform ; 10-segmented ; 601-677 (637)1* l° n g. i- e - as l° n g as or slightly 

 longer than half the body length, the ratio being 1 : 1-6-2-0 (i-8), and about as long as the 

 hind legs, the ratio 1 : 10-11 (1-07). Scape 43-49 (46)10. long and 49-55 (52)10. wide at base ; 

 always with 4 h.s. Pedicel 58-64 (6i)u. long and 37-43 (40)10. wide ; with 7-11 (8-4) h.s. and a 

 sensillum placodenm. Flagellum : Flagellar segment 27-31 (29) [o. wide, with segments VIII, 

 IX and sometimes VII inconsiderably wider. Segment III club-shaped and longest of all, 

 the ratio its length to the length of the terminal segment 1-7-2-3 (1-9) : 1, and its width to its 

 length 1 : 3-4-4-2 (4-0). Segments IV to IX rather barrel-shape ; the ratio width to length 

 of segment IX 1 : 1-4-1-8 (i-6). Terminal segment pear-shaped, with a narrowly constricted 

 or even pointed apex. Segments VI to X and sometimes V also, with a number of apically 

 knobbed, capitate sensory setae. In the following table, the lengths of the flagellar segments 

 and the number of setae on each are given :
