MORPHOLOGY AND TAXONOMY OF ADULT MALES 



Head subconical in dorsal view ; in lateral view flat, not obliquely elongated dorsoventrally, 

 anterodorsal bulge not pronounced ; length from apex to pronotal ridge 186-205 (average 199) 

 u., width across genae 182-198 (average 190) \l. Median crest sclerotized, distinctly polygonally 

 reticulated, with 7-1 1 (average 9) hair-like dorsal head setae. Midcranial ridge dorsally absent ; 

 ventrally reduced to a shorter or longer median bar with lateral arms, surrounding area sclero- 

 tized and showing distinct polygonal reticulation. Genae large, weakly sclerotized, with distinct 

 polygonal reticulation ; without setae. Eyes : two pairs, subequal ; corneae of dorsal eyes 

 19-25 (average 22) |j. in diameter and 2-7-3-4 (average 3) times as much apart ; those of the 

 ventral eyes 19-25 (average 22) [x in diameter and 1-2-1-8 (average 1-4) times as much apart. 

 Ocellus small, situated on a distinct protuberance which overhangs the postocular ridge. Ocular 

 sclerite well sclerotized, distinctly polygonally reticulated throughout. Preocular ridge long, the 

 ridges of each side ventrally meeting or almost meeting each other medially. Postocular ridge 

 well developed throughout. Interocular ridge broadly joining pre- and postocular ridges below 

 ocellus. Dorsal ocular setae absent. V entral head setae : 9-16 (average 13) f.s. and 5-9 (average 

 6-9) h.s., arranged in a broad band on anterior part of ocular sclerite, occasionally with some 

 (0-3, average 0-7) f.s. and some (0-1, average 0-5) h.s. occurring in the area anterior to this 

 sclerite, but with none between the eyes. Preoral ridge absent. Tendon-like apodeme variable, 

 occasionally fully developed, but usually reduced or absent. Cranial apophysis of medium 

 length ; apex trifurcate, extending to around the margin of the posterior level of the ventral 

 eyes. Mouth opening irregular. A nterior tentorial pits present, situated anterolateral to mouth 

 opening. 



Antennae 10-segmented, filiform ; 1030-1284 (average 1125) [x long, i.e. longer than half 

 body length (ratio 1 : 1-23-1-51, average 1-38), longer than posterior leg (ratio 1 : 1-42-1-52,
