198 MORPHOLOGY AND TAXONOMY OF ADULT MALES 



Disc pores present. Lateral ocelli well developed. Third antennal segment 

 longer than the terminal (1-4 or more times as long) ; the length of segment 

 III more than 5 times its width. Antennal setae about twice as long as the 

 body setae ; capitate, apically knobbed sensory setae entirely absent. 

 Proepisternum with dorsal and ventral margins ridge-like. Prescutal ridges 

 continuous postero-medially. Postmesostigmatal setae, alar setae and 

 metapostnotal ridge present. Middle legs shortest. Ostioles present. 

 Dorsal setae of abdominal segment VIII present. Glandular pouches and 

 their setae on abdominal segments VII and VIII ; the tail setae of segment 

 VIII rather long, the body being less than 8 times as long. Basal ridges of 

 the penial sheath medially separated . . . CEROPUTO group (p. 155) 



3 (1) Antennae comparatively long (the body 1-5 or less times as long) ; longer than 



the hind legs. Few capitate, apically knobbed sensory setae present on 

 antennal segments III to X. Antespiracular dorsal setae and pores absent. 

 Basalare weak and slender. Abdominal disc pores only present on segment 

 I. Setae of the glandular pouch include a pair of long tail setae, two setae of 

 medium, unequal lengths and a short one . OCTOCOCCUS group (p. 151) 



[Only one species, O. africanus.] 

 Antenna comparatively short (the body i-6 or more times as long) ; shorter 

 than the hind leg, or both subequal in length. Capitate, apically knobbed, 

 sensory setae only present on terminal antennal segment. Antespiracular 

 dorsal setae and pores present. Basalare comparatively stout. Abdominal 

 disc pores present on all abdominal segments. Setae of the glandular pouch 

 include a pair of long tail setae and one of medium length or short . . 4 



4 (3) The head and the body dorso-ventrally flattened ; ventral preocular depression 



entirely absent. Postoccipital ridge V-shaped. Postocular ridge dorsally 

 reduced. Prosternal ridge absent. Two antespiracular ventral setae 

 always present. Prescutal suture absent. The marginal ridge of the 

 basisternum anteriorly absent. Furca comparatively small. Hind legs 

 short, the body more than 2-2 times as long SACCHARICOCCUS group (p. 143) 



[Only one species, S. sacchari.] 



— The body cylindrical ; ventral preocular depression present. Postoccipital 



ridge U-shaped. Postocular ridge well developed. Prosternal ridge 

 distinct. Only one antespiracular ventral seta present. Prescutal suture 

 well-defined. The marginal ridge of the basisternum well developed. 

 Furca comparatively large. Hind legs long, the body less than 2-2 times 

 as long 5 



5 (4) Fleshy setae present on the body itself, giving the males a distinctive hairy 



appearance. Ventral ocular setae present. Genal setae more than 7, and 

 prosternal setae more than 3 . . . . PSEUDOCOCCUS group (p. 131) 



- Fleshy setae absent on the body itself. Ventral ocular setae absent. Genal 



setae less than 7, and prosternal setae less than 3 PLANOCOCCUS group (p. 93) 



Key to CEROPUTO Group of Genera 



Fleshy setae present on antennae and legs. Dorsal arm of midcranial ridge distinct. 

 Setae between the ventral simple eyes absent. Terminal antennal segment with 

 3 preapical large bristles and 2 smaller ones ; the preapical bristles about twice as 

 long as those of the two penultimate segments. Prosternum represented by a pair 

 of separate, small plates connected by the prosternal ridge. Prescutum 4 times or 

 more as long as scutum. Scutellum laterally supported by a distinct additional 

 ridge. Lateropleurite with an oval membranous area. Postmesostigmatal pores
