MORPHOLOGY AND TAXONOMY OF ADULT MALES 



Head subconical in dorsal view ; in lateral view dorsoventrally elongated, with anterodorsal 

 bulge not pronounced ; length from apex to pronotal ridge 201-232 (average 217) jjl, width 

 across genae 201-224 (average 213) y.. Median crest sclerotized, showing distinct polygonal 

 reticulation which enclose irregular striations ; with numerous (15-27, average 21) fleshy 

 dorsal head setae and 4-10 (average 8-i) hair-like ones. Midcranial ridge dorsally absent ; 

 ventrally strong, reaching ocular sclerite posteriorly, surrounding area weakly polygonally 

 reticulated. Genae large, sclerotized, with polygonal reticulation ; each with 9-18 (average 

 14) fleshy and 2-7 (average 4-4) hair-like genal setae. Eyes : two pairs, subequal ; corneae of 

 dorsal eyes 23-27 (average 25) \i in diameter and 1-8-2-7 (average 2-2) times as much apart ; 

 those of the ventral eyes 25-27 (average 26) \i in diameter and o-6-i-o (average 07) times as 

 much apart. Ocellus small. Ocular sclerite well sclerotized and polygonally reticulated 

 throughout. Preocular ridge extending only a very short distance below articular process. 

 Postocular ridge well developed throughout ; dorsal and ventral to ocellus the ridge usually 

 splits up with the anterior branch partly surrounding ocellus. Interocular ridge absent. 

 Dorsal ocular setae : 0-4 (average 2) f.s. and occasionally one h.s. on each side. Ventral head 

 setae consisting of 47-67 (average 53) f.s. and 3-8 (average 44) h.s., scattered over the ocular 

 sclerite, always with some (2-7, average 4-8) f.s. occurring in front of this sclerite and with
