no MORPHOLOGY AND TAXONOMY OF ADULT MALES 



Abdomen : 380-562 (448) u. long and 281-342 (319) fx wide. Tergites of segments I, II and 

 III small ; those of segments VIII and IX + X large. The sternites of segment VIII distinct. 

 Ostioles well developed, with a 52-61 (55) [x long orifice. Abdominal setae on each side : 

 Dorsal setae 2-4 on segments I to VII, and always 2 on segment VIII. Pleural setae 3-5 on 

 segments I to VIII, including one conspicuously longer seta on the latter. Ventral setae 1-2 

 on segment II, 2-3 on segment III, always 2 on segments IV to VII, and absent on segment 

 VIII. Abdominal disc pores : Segments I to VII with 9-23 (14-1), 4-11 (7-4), 4-11 (7-4). 

 5-10 (6-7), 5-10 (6-9) 4-9 (7-3), and 5-12 (7-8) pleural pores, respectively. 



Setae of glandular pouch include two, 275-305 (290) jx long tail setae, and one, 79-107 (92) y. 

 long seta ; the ratio length of the tail setae to the total length of the body 1 : 3-7-4-6 (4-0). 



Genital segment : Conical in dorsal view, extending posteriorly into a tubular, apically 

 rounded style ; the latter slightly curving upwards in lateral view. Penial sheath 11 3-1 34 

 (i22)[x long and 85-98 (89)fx wide, i.e. the ratio 1-3-1-5 : 1 (1-4 : 1), and the ratio its length to 

 the total body length 1 : 8-9-10-6 (1 : 9-5). Basal ridge of penial sheath with a small internal 

 projection ; process of penial sheath well developed, with 3-4 (3-6) setal sensilla. Aedeagus 

 tapering to a pointed end ; internal genital aperture large. Setae of genital segment slightly 

 smaller than the other body setae ; the dorsal always includes 3 h.s. on each side, near the 

 base of the style ; the ventral group consists of 3-4 (3-4) h.s. on each side of the penial sheath 



Material : 10 specimens examined, collected by D. N. McNutt, on roots of Coffea 

 arabica, in Buwagogo, Uganda, 23.viii.1961. 



NIPAECOCCUS Sulc, 1945 



Nipaecoccus vastator (Maskell) 



(Text-figs, n, 12) 



Only the winged males known. A slender species, of medium size, with moderately long 

 antennae and legs. Mounted specimens 1 148-1358 (1246) [x long, 280-322 (294)0. wide and 

 2310-2660 (2520) |x wing expanse. 



Body setae and disc pores : The antennae with fleshy and hair-like setae, approximately 

 37 (x long ; the body itself and the legs with hair-like setae only, about 28 jx long. Quadrilocular 

 and occasionally quinquelocular disc pores, about 6jx in diameter, occur on the head, thorax 

 and abdomen ; Beardsley (i960) observed few pores with 6 peripheral oculi. 



Head : Subtetrahedron ; subtriangular in dorsal and front views ; ventral preocular 

 depression hardly indicated in lateral view. Length from apex to postoccipital ridge 1 07-1 31 

 (n6)jx ; from apex to neck 177-198 (186) (x ; width across the genae 207-244 (229) jx. Dorsal 

 arm of midcranial ridge anteriorly detached from other arms by a short distance, and 

 posteriorly meeting the postoccipital ridge ; ventral and lateral arms forming a T-shaped ridge. 

 Postoccipital ridge U-shaped and anteriorly continuous with the preocular ridges. Dorsomedial 

 part of epicranium weakly sclerotized. Preocular -f- interocular ridges posteriorly joined to 

 postocular ridge below the ocellus ; preocular ridge without any apparent ventral rudiment. 

 Preoral ridge slender. Eyes : Dorsal simple eyes project beyond the outer margins of the 

 head in dorsal view ; their corneae 34-46 (40) [x in diameter and separated by 107-125 (ii3)(x, 

 i.e. 2-5-3-5 (2-8) times as much as their diameter apart. Ventral simple eyes only 31-43 (37) jx 

 in diameter, and separated by 27-40 (34) u.. Lateral ocelli large. Cranial apophysis apically 

 truncate. Tentorial bridge slender. Dorsal head setae 10-14 ( IJ '8), on each side of the median 

 line ; each gena almost always with 3 genal setae (occasionally 2). Ventral head setae on each 

 side as follows : 5-6 (5-4) between the ventral eyes ; 8-12 (io-i) forming on both sides a
